How to Undo a CSV Import in QuickBooks Online (If Something Goes Wrong)

Rolling back is important because mistakes happen, especially with large CSV uploads.

In SaasAnt, there are two common recovery options:

1. Undo the uploaded batch (where available in the import history or dashboard)

2. If you need a full cleanup, use Delete Transactions to remove the imported records from QuickBooks Online (especially when the mapping was wrong or the batch created unusable data).

Tip: Always download your import report before rolling anything back. It makes it easier to re-import cleanly.

Common QBO CSV Import Problems (and Quick Fixes)

“Some rows did not import”

Usually caused by:

• Missing required fields (like customer/vendor, account, or date)

• Invalid product/service names

• Unsupported fields for that transaction type

Fix: correct the CSV, then re-upload the file.

“Dates are not recognized”

Fix: use one consistent date format across the full file and match the date format selection during import.

“Duplicate names already exist”

QuickBooks often blocks importing contacts that already exist with the same name. Fix duplicates first, then re-import.
