What is a QIF file? The history of Quicken Interchange Format
QIF stands for Quicken Interchange Format. It is one of the oldest electronic financial data formats still in use today. Intuit created QIF in the early 1990s as the native export format for Quicken, their personal finance software that dominated the market throughout the 1990s and 2000s.
QIF was the standard way to move financial data between banks, Quicken, Microsoft Money, and other personal finance tools before OFX was developed. Millions of users exported decades of financial history in QIF format, and many of those archives still exist on old hard drives, backup CDs, and legacy systems.
Although Intuit officially deprecated QIF in favor of QFX (Quicken Web Connect) in 2005, the format remains widely used. Many banks still offer QIF downloads, especially for personal banking accounts. Legacy Quicken installations (Quicken 98 through Quicken 2015) store data in QIF format. And thousands of financial tools and scripts still produce QIF output.
The format itself is remarkably simple. Each line starts with a single-character prefix that indicates the field type, and transactions are separated by a caret (^) symbol. This simplicity is both its strength (easy to parse) and its limitation (no support for investment accounts, split transactions, or multi-currency data in the basic banking type).
