# My import file has errors

Use row errors and column mapping to correct a data import before committing it.

Canonical: https://demo.qixcount.com/help/fix-a-problem/import-file-has-errors

Who can do this: Owners, or people with the create and posting permissions for the import type

Where: Books, then Import data

You'll need: Your source CSV and its review page; statement files use the separate bank importer

One invalid row or missing required column blocks the whole data import. Ready rows are not added around the errors.

## Fix the first error

1. Open the upload's review page under **Import data**.
2. Read each row number and reason under **Commit is blocked. Fix every error.**
3. Correct a wrong column selection in the mapping controls.
4. Select **Update mapping and review**.
5. For errors in row contents, correct the CSV and upload it again.

Use the source row number to find mismatched cell counts, invalid amounts or missing data. If a thousands comma split one amount into cells, quote that amount or remove its thousands comma. A required column must be mapped even if the source uses a different heading.

## Check the result before committing

Review duplicate skips as well as errors. A duplicate skip is not a new record. Expired uploads have cleared rows and need a new upload. Permissions and posting rules are checked again when committing.

Nonprofit supports list imports, but not open invoice, open bill or opening-balance imports. Use the [move guide](https://demo.qixcount.com/help/moving-to-qixcount/prepare-and-review-a-csv) for the supported sequence.

If the same error remains, contact support with the import type, row number and exact message. Remove personal data before sharing a sample. Bank statement uploads use the separate [statement importer](https://demo.qixcount.com/help/banking/import-a-statement-file).
