Open Financial Exchange (OFX) is a data-stream format for exchanging financial information that evolved from Microsoft's Open Financial Connectivity (OFC) and Intuit's Open Exchange file formats.[3]


Microsoft, Intuit and CheckFree announced the OFX standard on 16 January 1997. The first OFX specification, version 1.0, was released on 14 February 1997.[3] The specification allows for bank- and application-specific extensions, although only a subset is necessary to describe a financial transaction.

Versions 1.0 through 1.6 relied on SGML for data exchange, but later versions are XML based. According to the main OFX site, "The specification is freely licensed, allowing any software developer to design an interface that will be supported on the front-end."[citation needed]

In 2019, OFX's consortium joined Financial Data Exchange (FDX) consortium,[4][5] that manage nowadays OFX working group.[5]


The latest reference document (Functional Specification) describing the standard was published in October 2020, in version 2.3, by the FDX consortium's OFX working group.[6]

Support in various countries[edit]

Many banks in the US let customers use personal financial management software to automatically download their bank statements in OFX format, but most Canadian,[7][8][9] United Kingdom and Australian banks do not allow this, however, many banks do support downloading financial data in OFX, QFX, QIF, or spreadsheet format via their web interface for later import into financial software.

Intuit and QFX[edit]

QFX is a proprietary variant of OFX used in Intuit's products. In Intuit products, OFX is used for Direct Connect and QFX for Web Connect. Direct Connect allows personal financial management software to connect directly to a bank OFX server, whereas in Web Connect, the user needs to log in and manually download a .qfx file and import it into Quicken.[10]

It appears the bank regulators have struck. http://faq.quickensoftware.ca/detail.php?buid=QK&qbid=QK1054 indicates that Online Banking Booster (the Intuit name for DirectConnect in Canada) was discontinued for all Canadian banks at the end of October 2008. The banks have apparently all added additional security questions at login that Quicken can't handle, so Intuit just bailed. In the US, Intuit has pushed the use of an additional token (CLIENTUID) as suitable for satisfying regulator's insistence on multifactor authentication. It remains to be seen how well that rolls out. {{cite mailing list}}: External link in |quote= (help)
