Bank CSV Normalizer

Clean inconsistent bank CSV exports locally in your browser and export a standardized CSV without uploading your financial data.

Includes:

- local browser-only processing

- common date, description, amount, debit, and credit column mapping

- normalized transaction CSV export

- exception report for possible duplicates and missing or invalid values

- synthetic sample file and quick-start instructions

No bank login or connection is required. Files are not uploaded or sent to a server. This is not a PDF/OCR converter, bookkeeping, accounting, tax, investment, or financial advice tool, and it does not guarantee reconciliation or financial accuracy. Review normalized output before using it in any accounting or financial system.
