I validate every customer export file before migrating clients off QuickBooks Online. Last week the tool caught 15 records with company names over the 100-character limit and 3 with invalid email formats. Without the check, the destination system would have silently truncated the names and rejected the emails with no explanation.

How People Use This
We were moving 2,400 customer records from QBO to Xero and the export had 87 rows with missing Display Names and 12 with balance amounts stored as text instead of numbers. The validator flagged every issue with row numbers so our team fixed them in 20 minutes instead of discovering failures mid-import.
Our multi-entity firm exports customer lists quarterly for reconciliation. The validator caught that one entity's export had duplicate email addresses across 9 customer records and address fields with special characters that would break our downstream import. Saved us from corrupting the master customer database.
Why Validate Customer Data?
Customer Export Accuracy
QuickBooks customer exports must have correct names and contact information for migration.
Missing or malformed data causes import failures in destination systems.
What This Tool Checks
We validate your QBO customer export:
- Required columns present (Customer/Display Name)
- Email addresses properly formatted
- Balance amounts are numeric
- Contact information is valid
Your Data Stays Private During Validation
Every Row Checked
Each record is validated against format rules. Catch errors before they reach your platform.
Runs in Your Browser
Validation happens locally. Your data never leaves your browser.

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.
