The format your bank exports, the format your tools want
OFX is what the "download transactions" button at most banks actually produces - a format built in the 1990s for Quicken and Microsoft Money, both long gone from most people’s lives. The data inside is perfectly good: every transaction with its date, signed amount, payee and the bank’s own unique ID. This converts it to a CSV you can open in Excel, feed to a budgeting spreadsheet, or hand to an accountant.
Both OFX generations are handled - the SGML-based 1.x that omits closing tags and the XML-based 2.x - plus Quicken’s .qfx variant. Dates arrive in ISO form, amounts as plain signed numbers that sum correctly, and the FITID column gives you reliable de-duplication across overlapping exports. Prefer a ready workbook? OFX to Excel types the amount column numerically. Older banks sometimes offer QIF instead; that is QIF to CSV.
A bank statement is the file you never upload casually
Every row in an OFX says where you shopped, what you earned, who you paid. A converter that stores uploads is the wrong place for that, full stop. Here the statement is parsed entirely in memory, never written to disk, never logged, and deleted the moment your download is delivered - on a server with swap disabled, so nothing can be paged out either.
The parser itself was written for this site rather than imported: it reads the tag structure directly without an XML engine, so XML-specific attacks (external entities, expansion bombs) have no surface to land on. On the way out, text cells get the standard spreadsheet formula-injection guard while amounts are validated as pure numbers and left clean for summing.
