QuickBooks Online Bank Export Validator

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.

Required column is Date (transaction date). Either Amount OR Payment/Deposit columns should be present.

Some exports use a single Amount column (positive/negative), others use separate Payment and Deposit columns.

QuickBooks expects MM/DD/YYYY format. If your bank export uses different date formats (DD/MM/YYYY or YYYY-MM-DD), the validator will flag them for correction before importing.

Common causes include incorrect column order, unsupported date formats, special characters, or file encoding issues. Use the validator to identify the specific problem.

The validator identifies duplicate entries before import. Check for matching date, description, and amount fields, then remove duplicates from your CSV file before uploading.

QuickBooks has a 350KB file size limit for CSV imports. The validator will notify you if your file exceeds this—split large exports into multiple smaller files.

QuickBooks limits imports to approximately 1,000 transactions per file. The validator will flag if you exceed this limit, so break larger exports into multiple uploads.

This indicates a file encoding problem. Save your CSV as UTF-8 encoding instead of ASCII or ANSI. The validator checks encoding compatibility before import.

Upload your bank export CSV to this validator to check for format errors, missing data, invalid dates, and other issues before attempting to import into QuickBooks.
