BankFileFix, for the bank files QuickBooks refuses to eat

Field notes

The visible workflow accepts CSV, XLS, and XLSX files, including several files for merging and de-duplication. Review controls cover duplicate transactions, overlapping date ranges, header-row placement, column adjustment, and banks that reverse debit and credit signs. Ambiguous dates can be interpreted as DD/MM/YYYY or MM/DD/YYYY. The page states that files remain on the user’s device and that no signup is needed, though those privacy and access claims are not independently verified here.
