Why Validate Bank Files?

Frequently Asked Questions

Your data never leaves your device. All files are processed entirely in your browser using client-side JavaScript - no data is stored on our servers or sent anywhere. There's no account to hack, no database storing your files, and no API connections to your bank or accounting software. You upload, convert, download, and we forget it immediately.
No payment or signup required. You can upload your file, see a free preview of the conversion results, and verify everything looks correct before paying anything. If it doesn't work for your files, you haven't wasted any money. We only charge when you're satisfied and ready to download the final converted file.
You can, but free scripts and AI often miss edge cases that break real-world data: missing SKUs, currency formatting quirks, tax calculation errors, or date format mismatches. We have battle-tested validators specifically designed for accounting software imports that catch these issues before they corrupt your books. Plus, you get instant browser-based conversion without installing Python or managing dependencies.
OFX is the open standard. QFX is Quicken's proprietary variant. QBO is QuickBooks' variant. All three use the same underlying structure and are validated the same way.
Required fields are: FITID (transaction ID), DTPOSTED (date), and TRNAMT (amount). Optional fields include NAME, MEMO, TRNTYPE, and CHECKNUM.

Yes, any bank that provides OFX/QFX/QBO downloads. The format is standardized across financial institutions.
Your file is processed entirely in your browser. No financial data is uploaded to our servers.
OFX parsing fails due to malformed XML tags, encoding issues, or version incompatibilities. Open the file in a text editor, check for mismatched tags, verify the ENCODING line (USASCII vs UTF-8), and ensure proper formatting before importing.
QuickBooks Desktop requires .QBO format, not .QFX. Convert your QFX file to QBO by opening it in a text editor and saving as .QBO, or use a conversion tool. Some banks only export in QFX format.
Yes. OFX and QBO files have similar XML structure. You can open the OFX file in Notepad and save it as .QBO, or use an automated converter tool like OFX2QBO Convert.
Bank files typically use ENCODING:USASCII or ENCODING:UTF-8. If you see import errors with special characters, try changing the encoding declaration at the file's top from USASCII to UTF-8 or vice versa.
Open the QBO file in a text editor and look for invalid characters like &, <, or extra quotation marks. Remove or correct these characters, save the file, and re-download from your bank if problems persist.
