Objective, Primary [Text Block] oef_ObjectivePrimaryTextBlock
The Invesco BulletShares 2029 Municipal Bond ETF (the “Fund”) seeks to track the investment results (before fees and expenses) of the Invesco BulletShares® Municipal Bond 2029 Index (the “Underlying Index”).
Expense Heading [Optional Text] oef_ExpenseHeading Fund Fees and Expenses
Expense Narrative [Text Block] oef_ExpenseNarrativeTextBlock
This table describes the fees and expenses that you may pay if you buy, hold, and sell shares of the Fund (“Shares”). You may pay other fees, such as brokerage commissions and other fees to financial intermediaries, which are not reflected in the table and example below.
Operating Expenses Caption [Optional Text] oef_OperatingExpensesCaption Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your investment)
Expense Example [Heading] oef_ExpenseExampleHeading Example.
Expense Example Narrative [Text Block] oef_ExpenseExampleNarrativeTextBlock
This example is intended to help you compare the cost of investing in the Fund with the cost of investing in other funds.
The example assumes that you invest $10,000 in the Fund for the time periods indicated and then sell all of your Shares at the end of those periods. The example also assumes that your investment has a 5% return each year and that the Fund's operating expenses remain the same. This example does not include brokerage commissions that investors may pay to buy and sell Shares. Although your actual costs may be higher or lower, your costs, based on these assumptions, would be:
Portfolio Turnover [Heading] oef_PortfolioTurnoverHeading Portfolio Turnover.
Portfolio Turnover [Text Block] oef_PortfolioTurnoverTextBlock
The Fund pays transaction costs, such as commissions, when it purchases and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate will cause the Fund to incur additional transaction costs and may result in higher taxes when Shares are held in a taxable account. These costs, which are not reflected in Total Annual Fund Operating Expenses or in the example, may affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was 0% of the average value of its portfolio.

Strategy [Heading] oef_StrategyHeading Principal Investment Strategies
Strategy Narrative [Text Block] oef_StrategyNarrativeTextBlock
The Fund generally will invest at least 80% of its total assets in the securities that comprise the Underlying Index. Strictly in accordance with its guidelines and mandated procedures, Invesco Indexing LLC (the “Index Provider”) compiles and maintains the Underlying Index. The Index Provider is affiliated with Invesco Capital Management LLC, the Fund’s investment adviser (the “Adviser”), and Invesco Distributors, Inc., the Fund’s distributor (the “Distributor”).
The Underlying Index seeks to measure the performance of a portfolio of U.S. dollar-denominated investment-grade municipal bonds with maturities or, in some cases, “effective maturities,” in the year 2029 (collectively, “2029 Bonds”). Certain bonds in which the Fund may invest may contain embedded issuer call options. An embedded issuer call option means that the bond’s issuer has the right to redeem a bond prior to its designated maturity date. Accordingly, the effective maturity date of a bond reflects an assessment of when that bond is likely to be called by the issuer, or in the alternate, the bond’s stated maturity date (if it is not called by the issuer). With respect to establishing the effective maturity of a bond, the effective maturity is the actual year of maturity (i) if no embedded issuer call option exists for a bond; (ii) if a bond contains an embedded issuer call option, with the first call date within 13 months of maturity and a par call price; and (iii) unless the yield to next call date is less than the yield to maturity, in which case the bond’s effective maturity is deemed to be the
year of the next call date. The effective maturity of eligible pre-refunded municipal bonds with a known pre-refunded date shall be the year of the pre-refunded date.
In selecting components for inclusion in the Underlying Index, the Index Provider begins with an investment universe of U.S. dollar-denominated bonds issued by U.S. states, state agencies, territories and possessions of the United States, the District of Columbia or local governments. To be eligible for inclusion in the Underlying Index, bonds must (i) be 2029 Bonds (i.e., will mature or will have an effective maturity in the year 2029); (ii) be exempt from federal income tax; (iii) pay fixed amounts of interest; (iv) be rated at least BBB- by S&P Global Ratings, a division of S&P Global Inc. (“S&P”), or Fitch Ratings Inc. (“Fitch”), or at least Baa3 by Moody’s Investors Service, Inc. (“Moody’s”); and (v) have at least $15 million in face value outstanding (current Underlying Index components require 80% of the initial minimum face value qualification to remain eligible (e.g., $12 million in face value outstanding)). The eligible universe may include callable, puttable, and pre-refunded bonds.
2029 Bonds selected for inclusion in the Underlying Index are market value weighted, with a 5% limit on individual issuers applied at each monthly rebalance prior to the final maturing year of the Underlying Index. Bonds held by the Fund generally will be held until they mature, are called or no longer meet the eligibility requirements of the Underlying Index and are removed from the Underlying Index.
As of October 31, 2024, the Underlying Index was comprised of 1,973 constituents.
The Fund will terminate on or about December 15, 2029 without requiring additional approval by the Board of Trustees (the “Board”) of Invesco Exchange-Traded Self-Indexed Fund Trust (the “Trust”) or Fund shareholders, although the Board may change the termination date. In connection with the termination of the Fund, the Fund will make a cash distribution of its net assets to then-current shareholders after making appropriate provisions for any liabilities of the Fund. The Fund does not seek to distribute any predetermined amount of cash at maturity. During the maturing year of the Underlying Index (i.e., 2029), no new constituents are added and the Underlying Index does not rebalance. In the last twelve months of operation, when the 2029 Bonds held by the Fund mature or are called, the proceeds are not reinvested in 2029 Bonds. Instead, the Fund will invest such proceeds in any combination of variable rate demand obligations (“VRDOs”), certain derivatives (i.e., exchange-traded futures on fixed-income securities, fixed-income security indices, interest rates and currencies; exchange-traded and over-the-counter (“OTC”) options on fixed-income securities, interest rates, currencies, interest rate futures contracts, and fixed-income security indices; exchange-traded and OTC interest rate and inflation swaps; and OTC total return swaps and forwards on fixed-income securities, fixed-income security indices, and fixed-income security futures), exchange-traded funds (“ETFs”), including affiliated ETFs, affiliated money market funds, cash or cash equivalents and investment-grade short-term commercial paper, as well as municipal bonds not included in the Underlying Index, but which the Adviser believes will help the Fund track the Underlying Index.
The Fund should not be confused with a target date fund, which has assets that are managed according to a particular glidepath that illustrates how its investment strategy becomes increasingly conservative over time.
The Fund does not purchase all of the securities in the Underlying Index; instead, the Fund utilizes a “sampling” methodology to seek to achieve its investment objective.
Concentration Policy. The Fund will concentrate its investments (i.e., invest more than 25% of the value of its net assets) in securities of issuers in any one industry or group of industries only to the extent that the Underlying Index reflects a concentration in that industry or group of
industries. The Fund will not otherwise concentrate its investments in securities of issuers in any one industry or group of industries.

Invesco BulletShares 2029 Municipal Bond ETF | Market Risk [Member]  
Prospectus [Line Items] oef_ProspectusLineItems  
Risk [Text Block] oef_RiskTextBlock Market Risk. Securities in the Underlying Index are subject to market fluctuations. You should anticipate that the value of the Shares will decline, more or less, in correlation with any decline in value of the securities in the Underlying Index. Additionally, natural or environmental disasters, widespread disease or other public health issues, war, military conflicts, acts of terrorism, economic crises or other events could result in increased premiums or discounts to the Fund’s net asset value (“NAV”).
Invesco BulletShares 2029 Municipal Bond ETF | Index Risk [Member]  
Prospectus [Line Items] oef_ProspectusLineItems  
Risk [Text Block] oef_RiskTextBlock Index Risk. Unlike many investment companies, the Fund does not utilize an investing strategy that seeks returns in excess of the Underlying Index. Therefore, the Fund would not necessarily buy or sell a security unless that security is added or removed, respectively, from the Underlying Index, even if that security generally is underperforming. Additionally, the Fund rebalances its portfolio in accordance with the Underlying Index, and, therefore, any changes to the Underlying Index’s rebalance schedule will result in corresponding changes to the Fund’s rebalance schedule.
Invesco BulletShares 2029 Municipal Bond ETF | Municipal Securities Risk [Member]  
Prospectus [Line Items] oef_ProspectusLineItems  
Risk [Text Block] oef_RiskTextBlock Municipal Securities Risk. Litigation, legislation or other political events, local business or economic conditions or the bankruptcy of the issuer could have a significant effect on the ability of an issuer of municipal securities to make payments of principal and/or interest. Political changes and uncertainties in the municipal market related to taxation, legislative changes or the rights of municipal security holders can significantly affect municipal securities. Because many securities are issued to finance similar projects, especially those relating to education, health care, transportation and utilities, conditions in those sectors can affect the overall municipal market. In addition, changes in the financial condition of an individual municipal issuer can affect the overall municipal market. If the Internal Revenue Service (“IRS”) determines that an issuer of a municipal security has not complied with applicable tax requirements, interest from the security could become taxable and the security could decline significantly in value.
Invesco BulletShares 2029 Municipal Bond ETF | Fixed-Income Securities Risk [Member]  
Prospectus [Line Items] oef_ProspectusLineItems  
Risk [Text Block] oef_RiskTextBlock Fixed-Income Securities Risk. Fixed-income securities are subject to interest rate risk and credit risk. Interest rate risk refers to fluctuations in the value of a fixed-income security resulting from changes in the general level of interest rates. When the general level of interest rates goes up, the prices of most fixed-income securities go down. When the general level of interest rates goes down, the prices of most fixed-income securities go up. Fixed-income securities with longer maturities typically are more sensitive to changes in interest rates, making them more volatile than securities with shorter maturities. Credit risk refers to the possibility that the issuer of a security will be unable and/or unwilling to make timely interest payments and/or repay the principal on its debt. Debt instruments are subject to varying degrees of credit risk, which may be reflected in credit ratings. There is a possibility that the credit rating of a fixed-income security may be downgraded after purchase, which may occur quickly and without advance warning following sudden market downturns or unexpected developments involving an issuer, and which may adversely affect the liquidity and value of the security.
Invesco BulletShares 2029 Municipal Bond ETF | Changing Fixed-Income Market Conditions Risk [Member]  
Prospectus [Line Items] oef_ProspectusLineItems  
Risk [Text Block] oef_RiskTextBlock Changing Fixed-Income Market Conditions Risk. Fluctuations in the federal funds and equivalent foreign interest rates or other changes to monetary policy or regulatory actions may expose fixed-income markets to heightened volatility, perhaps suddenly and to a significant degree, and to reduced liquidity for certain fixed-income investments, particularly those with longer maturities, when rates increase. Such changes and resulting increased volatility may adversely impact the Fund, including its operations and return potential. It is difficult to predict the impact of interest rate changes on various markets. In addition, decreases in fixed-income dealer market-making capacity may also potentially lead to heightened volatility and reduced liquidity in the fixed-income markets. As a result, the value of the Fund's investments and share price may decline. Changes in central bank policies and other governmental actions and political events within the U.S. and abroad may also, among other things, affect investor and consumer expectations and confidence in the financial markets. This could result in higher than normal redemptions by APs (as defined herein), which could potentially increase the Fund’s portfolio turnover rate and transaction costs.
Invesco BulletShares 2029 Municipal Bond ETF | Tax Risk [Member]  
Prospectus [Line Items] oef_ProspectusLineItems  
Risk [Text Block] oef_RiskTextBlock Tax Risk. There is no guarantee that the Fund's income will be exempt from federal or state income taxes. Events occurring after the date of issuance of a municipal bond or after the Fund's acquisition of a municipal bond may result in a determination that interest on that bond is includible in gross income for federal income tax purposes retroactively to its date of issuance. Such a determination may cause a portion of prior distributions by the Fund to its shareholders to be taxable to those shareholders in the year of receipt. Federal or state changes in income or alternative minimum tax rates or in the tax treatment of municipal bonds may make municipal bonds less attractive as investments and cause them to lose value.
Invesco BulletShares 2029 Municipal Bond ETF | Industry Concentration Risk [Member]  
Prospectus [Line Items] oef_ProspectusLineItems  
Risk [Text Block] oef_RiskTextBlock Industry Concentration Risk. In following its methodology, the Underlying Index from time to time may be concentrated to a significant degree in securities of issuers operating in a single industry or industry group. To the extent that the Underlying Index concentrates in the securities of issuers in a particular industry or industry group, the Fund will also concentrate its investments to approximately the same extent. By concentrating its investments in an industry or industry group, the Fund may face more risks than if it were diversified broadly over numerous industries or industry groups. Such industry-based risks, any of which may adversely affect the companies in which the Fund invests, may include, but are not limited to, the following: general economic conditions or cyclical market patterns that could negatively affect supply and demand in a particular industry; competition for resources; adverse labor relations; political or world events; obsolescence of technologies; and increased competition or new product introductions that may affect the profitability or viability of companies in an industry. In addition, at times, such industry or industry group may be out of favor and underperform other industries or the market as a whole.
Invesco BulletShares 2029 Municipal Bond ETF | Fluctuation of Yield and Liquidation Amount Risk [Member]  
Prospectus [Line Items] oef_ProspectusLineItems  
Risk [Text Block] oef_RiskTextBlock Fluctuation of Yield and Liquidation Amount Risk. The Fund, unlike a direct investment in a bond that has a level coupon payment and a fixed payment at maturity, will make distributions of income that vary over time. Unlike a direct investment in bonds, the breakdown of returns between Fund distributions and liquidation proceeds are not predictable at the time of your investment. For example, at times during the Fund’s existence, it may make distributions at a greater (or lesser) rate than the coupon payments received on the Fund’s portfolio, which will result in the Fund returning a lesser (or greater) amount on liquidation than would otherwise be the case. The rate of Fund distribution payments may adversely affect the tax characterization of your returns from an investment in the Fund relative to a direct investment in bonds. If the amount you receive as liquidation proceeds upon the Fund’s termination is higher or lower than your cost basis, you may experience a gain or loss for tax purposes.
Invesco BulletShares 2029 Municipal Bond ETF | Call Risk [Member]  
Prospectus [Line Items] oef_ProspectusLineItems  
Risk [Text Block] oef_RiskTextBlock Call Risk. If interest rates fall, it is possible that issuers of callable securities with high interest coupons will “call” (or prepay) their bonds before their maturity date. If an issuer exercises such a call during a period of declining interest rates, the Fund may have to replace such called security with a lower yielding security. If that were to happen, the Fund’s net investment income could fall.
Invesco BulletShares 2029 Municipal Bond ETF | Extension Risk [Member]  
Prospectus [Line Items] oef_ProspectusLineItems  
Risk [Text Block] oef_RiskTextBlock Extension Risk. Extension risk is the opposite of reinvestment risk, and typically occurs when interest rates rise, thereby causing repayments of fixed-income securities to occur more slowly than expected by the market. This may drive the prices of these securities down because their interest rates are lower than the current interest rate and they have longer duration (resulting in increased sensitivity to interest rate changes).
Invesco BulletShares 2029 Municipal Bond ETF | Reinvestment Risk [Member]  
Prospectus [Line Items] oef_ProspectusLineItems  
Risk [Text Block] oef_RiskTextBlock Reinvestment Risk. Reinvestment risk is the risk that the Fund will not be able to reinvest income or principal at the same return it is currently earning. Reinvestment risk is greater during periods of declining interest rates, as prepayments often occur faster. It is related to call risk, since issuers of callable securities with high interest coupons may call their bonds before their maturity date. This may require the Fund to reinvest the proceeds at an earlier date, and it may be able to do so only at lower yields, thereby reducing its return.
Invesco BulletShares 2029 Municipal Bond ETF | Liquidity Risk [Member]  
Prospectus [Line Items] oef_ProspectusLineItems  
Risk [Text Block] oef_RiskTextBlock Liquidity Risk. Liquidity risk exists when a particular investment is difficult to purchase or sell. If the Fund invests in illiquid securities or current portfolio securities become illiquid, it may reduce the returns of the Fund because the Fund may be unable to sell the illiquid securities at an advantageous time or price.
Invesco BulletShares 2029 Municipal Bond ETF | Declining Yield Risk [Member]  
Prospectus [Line Items] oef_ProspectusLineItems  
Risk [Text Block] oef_RiskTextBlock Declining Yield Risk. During the final year of the Fund's operations, as the bonds held by the Fund mature and the Fund's portfolio transitions to cash and cash equivalents, the Fund's yield will generally tend to move toward the yield of cash and cash equivalents and thus may be lower than the yields of the bonds previously held by the Fund and/or prevailing yields for bonds in the market.
Invesco BulletShares 2029 Municipal Bond ETF | Issuer-Specific Changes Risk [Member]  
Prospectus [Line Items] oef_ProspectusLineItems  
Risk [Text Block] oef_RiskTextBlock Issuer-Specific Changes Risk. The value of an individual security or particular type of security may be more volatile than the market as a whole and may perform differently from the value of the market as a whole.
Invesco BulletShares 2029 Municipal Bond ETF | Sampling Risk [Member]  
Prospectus [Line Items] oef_ProspectusLineItems  
Risk [Text Block] oef_RiskTextBlock Sampling Risk. The Fund's use of a representative sampling methodology may result in it holding a smaller number of securities than are in the Underlying Index. As a result, an adverse development with respect to an issuer of securities held by the Fund could result in a greater decline in NAV than would be the case if the Fund held all of the securities in the Underlying Index. To the extent the assets in the Fund are smaller, these risks will be greater.
Invesco BulletShares 2029 Municipal Bond ETF | Non-Correlation Risk [Member]  
Prospectus [Line Items] oef_ProspectusLineItems  
Risk [Text Block] oef_RiskTextBlock Non-Correlation Risk. The Fund's return may not match the return of the Underlying Index for a number of reasons. For example, the Fund incurs operating expenses not applicable to the Underlying Index, and incurs costs in buying and selling securities, especially when rebalancing the Fund's securities holdings to reflect changes in the composition of the Underlying Index. Because the Fund issues and redeems Creation Units principally for cash, it will incur higher costs in buying and selling securities than if it issued and redeemed Creation Units in-kind. Additionally, the Fund's use of a representative sampling methodology may cause the Fund not to be as well-correlated with the return of the Underlying Index as would be the case if the Fund purchased all of the securities in the Underlying Index in the proportions represented in the Underlying Index. In addition, the performance of the Fund and the Underlying Index may vary due to asset valuation differences and differences between the Fund's portfolio and the Underlying Index resulting from legal restrictions, costs or liquidity constraints.
Invesco BulletShares 2029 Municipal Bond ETF | Authorized Participant Concentration Risk [Member]  
Prospectus [Line Items] oef_ProspectusLineItems  
Risk [Text Block] oef_RiskTextBlock Authorized Participant Concentration Risk. Only authorized participants (“APs”) may engage in creation or redemption transactions directly with the Fund. The Fund has a limited number of institutions that may act as APs and such APs have no obligation to submit creation or redemption orders. Consequently, there is no assurance that APs will establish or maintain an active trading market for the Shares. This risk may be heightened to the extent that securities held by the Fund are traded outside a collateralized settlement system. In that case, APs may be required to post collateral on certain trades on an agency basis (i.e., on behalf of other market participants), which only a limited number of APs may be able to do. In addition, to the extent that APs exit the business or are unable to proceed with creation and/or redemption orders with respect to the Fund and no other AP is able to step forward to create or redeem Creation Units (as defined below), this may result in a significantly diminished trading market for Shares, and Shares may be more likely to trade at a premium or discount to the Fund's NAV and to face trading halts and/or delisting. Additionally, investments in non-U.S. securities may have lower trading volumes or could experience extended market closures or trading halts. To the extent that the Fund invests in non-U.S. securities, it may face increased risks that APs may not be able to effectively create or redeem Creation Units, or that the Shares may be halted and/or delisted.
Invesco BulletShares 2029 Municipal Bond ETF | Cash Transaction Risk [Member]  
Prospectus [Line Items] oef_ProspectusLineItems  
Risk [Text Block] oef_RiskTextBlock Cash Transaction Risk. Most ETFs generally make in-kind redemptions to avoid being taxed on gains on the distributed portfolio securities at the fund level. However, unlike most ETFs, the Fund currently intends to effect creations and redemptions principally for cash, rather than principally in-kind, due to the nature of the Fund’s investments. As such, the Fund may be required to sell portfolio securities to obtain the cash needed to distribute redemption proceeds. Therefore, the Fund may recognize a capital gain on these sales that might not have been incurred if the Fund had made a redemption in-kind. This may decrease the tax efficiency of the Fund compared to ETFs that utilize an in-kind redemption process and there may be a substantial difference in the after-tax rate of return between the Fund and conventional ETFs.
Invesco BulletShares 2029 Municipal Bond ETF | Market Trading Risk [Member]  
Prospectus [Line Items] oef_ProspectusLineItems  
Risk [Text Block] oef_RiskTextBlock Market Trading Risk. The Fund faces numerous market trading risks, including the potential lack of an active market for the Shares, losses from trading in secondary markets, and disruption in the creation/redemption process of the Fund. In stressed market conditions, the market for Shares may become less liquid in response to deteriorating liquidity in the markets for the Fund’s portfolio holdings, which may cause a variance in the market price of Shares and their underlying NAV. In addition, an exchange or market may issue trading halts on specific securities or financial instruments. As a result, the ability to trade certain securities or financial instruments may be restricted, which may disrupt the Fund’s creation/redemption process, potentially affect the price at which Shares trade in the secondary market, and/or result in the Fund being unable to trade certain securities or financial instruments at all. In these circumstances, the Fund may be unable to rebalance its portfolio, may be unable to accurately price its investments and/or may incur substantial trading losses. Any of these factors may lead to the Shares trading at a premium or discount to the Fund's NAV.
Invesco BulletShares 2029 Municipal Bond ETF | Operational Risk [Member]  
Prospectus [Line Items] oef_ProspectusLineItems  
Risk [Text Block] oef_RiskTextBlock Operational Risk. The Fund is exposed to operational risks arising from a number of factors, including, but not limited to, human error, processing and communication errors, errors of the Fund’s service providers, counterparties or other third-parties, failed or inadequate processes and technology or systems failures. The Fund and the Adviser seek to reduce these operational risks through controls and procedures. However, these measures do not address every possible risk and may be inadequate to address these risks.
Invesco BulletShares 2029 Municipal Bond ETF | Shares May Trade at Prices Different than NAV [Member]  
Prospectus [Line Items] oef_ProspectusLineItems  
Risk [Text Block] oef_RiskTextBlock Shares May Trade at Prices Different than NAV. Shares trade on a stock exchange at prices at, above or below the Fund’s most recent NAV. The Fund’s NAV is calculated at the end of each business day and fluctuates with changes in the market value of the Fund’s holdings. The trading price of the Shares fluctuates continuously throughout trading hours on the exchange, based on both the relative market supply of, and demand for, the Shares and the underlying value of the Fund’s portfolio holdings. As a result, the trading prices of the Shares may deviate from the Fund’s NAV. ANY OF THESE FACTORS, AMONG OTHERS, MAY LEAD TO THE SHARES TRADING AT A PREMIUM OR DISCOUNT TO NAV.
