(.OFX/.QFX/.QIF/.QBO/.OFC) file converter
fixofx was open sourced from Wesabe. It converts various types of financial files including OFX 1.0 and QIF files to OFX 2.0, which is an XML-based format and so is easily parsed.
I wrote a Python script ofx2csv.py that converts OFX/QFX files to CSV, if anyone needs to do this programmatically.
