QuickBooks Online "file too large" bank upload error: how to fix it

QuickBooks Online accepts bank upload files of up to 350 KB and up to 1,000 transaction lines (Intuit's published limits). Larger files fail with "file too large" or a generic upload error.

Fix for CSV files

1. Open the CSV in a spreadsheet and split it by date into files under 1,000 rows each. Splitting on a month boundary is easiest to check.
2. Delete extra columns QuickBooks doesn't need. Keep Date, Description and Amount, or Date, Description, Credit and Debit.
3. Save as CSV (UTF-8) and upload each file in date order.

Fix for .qbo / .qfx files

A .qbo file can't be split safely by hand: it has a header and a balance block. Either re-download shorter date ranges from your bank, or convert the file to CSV and split that. Our free tie-out checker can turn any split CSV into a valid .qbo file in your browser.

Check you didn't lose anything

Add up each split file and compare the sum to the original. Then reconcile in QuickBooks against the statement ending balance.
