What is a .ofx file?
File extension details and usage information
The OFX (Open Financial Exchange) file format is a standardized specification for the electronic exchange of financial data between financial institutions, businesses, and consumers over the internet. Developed jointly by Microsoft, Intuit, and CheckFree in 1997, it was designed to streamline the process of downloading bank statements, credit card transactions, and investment data into personal finance management software. Unlike generic formats like CSV, OFX is structured using SGML or XML-based tags, which allows for a high degree of precision in identifying transaction types, unique transaction IDs, currency codes, and balances. This structure is critical for preventing duplicate entries during the reconciliation process. OFX supports a wide array of financial activities, including retail and business banking, bill payment, investment tracking, and tax data exchange. Because it is an open standard, it has been widely adopted by thousands of banks and financial software developers worldwide to ensure interoperability. While modern web APIs are increasingly used for direct bank connections, the OFX file remains a vital tool for manual data portability and offline financial record keeping.
