The full name of the QIF file format, originally created for Quicken. A simple text-based format that predates OFX, still encountered in legacy financial data exports and older software.
Understanding Quicken Interchange Format (QIF)
Quicken Interchange Format (QIF) is the legacy file format originally created by Intuit for their Quicken personal finance software. First introduced in the 1990s, QIF was one of the earliest standards for exchanging financial data between software applications and has been largely superseded by OFX/QFX.
QIF uses a minimalist text-based syntax where each line is prefixed by a single character that identifies the field type: D (date), T (amount), P (payee), N (check number), M (memo), L (category/account), and A (address). Transactions are separated by a caret (^) character on its own line.
While QIF is simple and human-readable, it lacks features critical for modern use: no unique transaction IDs (making duplicate prevention impossible), no standardized date format (different regions use different conventions), and limited support for complex transaction types like splits and transfers.
Why It Matters for Ecommerce
QIF files are still encountered when migrating data from older versions of Quicken, legacy accounting systems, or international banks that haven't adopted modern formats. Converting QIF to QBO or IIF with proper transaction IDs and standardized formatting ensures a clean import into QuickBooks without duplicates.
Practical Example
A QIF file with two transactions: !Type:Bank D02/15/2026 T-1500.00 PSupplier Payment MInvoice #4521 LAccounts Payable ^ D02/16/2026 T250.00 PCustomer Refund MOrder #789 LSales Returns ^ Each transaction block ends with ^ and the ! header identifies the account type.
