Writing OFX files to import into Sage

Convert regular bank and creditcard CSV, QFX, QBO and QIF files to OFX

Some versions of Sage still ship with an OFX parser engine that is not compatible with version 2 of the OFX specication, as such, you will need to apply OFX settings of Version 1.02 and select the format as SGML (as per image below).
