Every bank formats CSV differently and I used to waste hours debugging failed imports. Now I run a pre-flight check on every bank download before touching QuickBooks. Last week the validator caught that a Wells Fargo export had date fields reformatted by Excel into a format QBO silently rejects.

Which banks are supported?
We support CSV exports from all major US banks including Chase, Bank of America, Wells Fargo, Capital One, Citi, US Bank, PNC, and most regional banks. Column names are auto-detected.
What columns are required?
At minimum, a valid bank CSV needs a date column and an amount column. Description/payee is optional but recommended. We auto-detect various column naming conventions.
What happens to my Banking file during validation?
Your Banking file is validated entirely in your browser — nothing is uploaded to any server. The Bank CSV validation runs client-side using JavaScript.

How People Use Bank CSV
We were migrating historical bank transactions from an old system and the CSV exports had encoding issues and empty rows scattered throughout. The validator checked 14,000 rows and flagged 47 corrupted entries that would have broken our QuickBooks import. Saved us a full day of troubleshooting.
I validate bank CSV exports from 6 different institutions before they go into our reconciliation pipeline. The auto-detection correctly identified column names from Chase, Bank of America, and Capital One without any manual mapping. It verified 38,000 transactions last quarter with zero false positives.
