Convert QFX to QDF

A bank or brokerage may supply transactions as a QFX Web Connect file, while Quicken for Windows requires its native QDF data file for continued bookkeeping. The conversion consists of importing the QFX file into Quicken and saving the resulting data file; renaming the extension does not convert it.

What the QFX format is

QFX, or Quicken Financial Exchange, is Quicken's variation of the OFX financial-data format. Banks, credit-card companies, and brokerages use it to distribute downloaded account activity, including transactions, dates, amounts, payees, balances, and, for supported investment accounts, security activity.

A QFX file is an interchange file for importing transactions into Quicken. It is not a complete Quicken database and normally does not include the full account history, categories, reminders, reports, memorized transactions, or other data already maintained in a QDF file. The financial institution's download service may also require an eligible account or an active Quicken service.

What the QDF format is

QDF is the native data-file format used by Quicken for Windows. It stores the Quicken dataset, including accounts, imported transactions, categories, balances, securities, reminders, and report definitions. Attachments and some supporting information may be stored in associated folders or files rather than inside the QDF file itself.

QDF is suitable for ongoing bookkeeping, reconciliation, reporting, and local backups in Quicken for Windows. It is a proprietary application database, not a general-purpose exchange format for other accounting programs.

How to convert QFX to QDF

1. Install and open a supported version of Quicken for Windows. Make sure the destination data file is the one that should receive the transactions.
2. Create a backup before importing. Use File → Copy or Backup File and select the backup option.
3. Choose File → Import and select Web Connect File or the similarly named Bank or Brokerage File option, depending on the Quicken release.
4. Select the .qfx file and continue through the import prompts. When Quicken identifies the institution, link the download to the existing account if that account is already present. Create a new account only when the QFX data represents an account not yet in the file.
5. Review the imported entries in the account register. Match downloaded transactions to existing entries, accept new entries, verify transaction signs and dates, and correct categories, payees, and transfers.
6. Check the opening and ending balances against the bank statement, then reconcile the account. Quicken saves the imported data in the current QDF data file. Use File → Show this file on my computer to locate it, or use File → Copy or Backup File to create a separate QDF copy for archiving.

Quicken may reject a file if it is malformed, belongs to another institution, or uses an OFX variant that the installed release does not support. Do not rename .ofx to .qfx: the extension change does not add the institution information or compatibility required by Quicken.

Compatibility and limitations

There is no reliable general-purpose online or desktop converter that turns arbitrary QFX data into a complete QDF database. Quicken is the appropriate conversion tool because it interprets the institution identifier, account type, transaction structure, investment data, and duplicate-matching information during import.

QFX imports can contain incomplete payee names, missing categories, incorrect transaction signs, unsupported transaction types, or duplicates. Compare the register with the source statement and correct or remove entries before reconciliation. An import cannot recreate information absent from the QFX file, such as older Quicken-only history, customized reports, reminders, or attachments.

Online conversion services are not a practical alternative: they generally cannot generate a valid native QDF dataset and would expose bank transactions and account identifiers to a third party. Quicken for Mac uses a different native data structure and does not use QDF as its normal data-file format. A Mac user who specifically needs QDF must open or migrate the data using Quicken for Windows, subject to the versions and migration paths supported by Quicken.
