Separate currencies. Exclude pending movements.

PayPal exports are detected from their headers, not fragile column positions. Completed net movements become one file per currency; pending and zero-value rows stay visible in the report.

Secure one-time checkout. Card details are handled by the payment provider and never touch CSV Mender.

Your file stays yours.

Do you upload my financial data?

No. Parsing, validation, preview and export happen in your browser. During checkout, local browser storage keeps a temporary recovery copy on this device; it is removed after the paid file is restored or when you clear it.

Does this connect to my accounting account?

No. CSV Mender does not request bank access or accounting credentials. You import the downloaded file yourself.

Is every file guaranteed to import?

No tool can control organization settings or field mapping. CSV Mender checks documented format constraints and clearly flags rows that still need review.
