Why won't my bank CSV import into QuickBooks?

QuickBooks rejects a CSV when the columns, date format, amounts, headers or transaction structure do not match its expected import format. BankFileFix identifies and fixes many of these problems before export.

Can BankFileFix remove duplicate bank transactions?

BankFileFix detects possible duplicates using transaction date, amount and description. You review the duplicates before removing them.

Why QuickBooks rejects bank CSV files

The usual causes are mismatched columns, inconsistent date formats, currency symbols in the amount column, repeated header rows, and debit/credit values split across two columns. Each is fixable here.
