Fixing rows that did not import

Download the error report from the import, which names the row number, the field and the reason for every row that failed.

2 min readUpdated 6 August 2026

Open the import from Import Data and download the error report. It is a CSV with three columns, Row, Field and Message, naming exactly which row failed and why.

The usual causes

  • A missing name, because a customer with no name in any column cannot be created
  • An unreadable date, which is why a column mixing formats lands some rows and not others
  • An email that is not an email address, often a note that has drifted into the wrong column
  • Blank rows at the bottom of the spreadsheet, which are harmless and can be ignored
  • A price with a currency symbol or thousands separator in an unexpected place

How to fix them

  1. 1Download the error report
  2. 2Open your original export alongside it and find those row numbers
  3. 3Correct them in the spreadsheet, or delete them if they are junk
  4. 4Save a new CSV containing just the corrected rows
  5. 5Import that file with the duplicate rule set to Update

Importing only the failures is deliberate. The rows that worked the first time are already in, and re-importing everything just makes a longer report to read.

If nearly every row failed

That is a mapping problem rather than a data problem. Start the import again and look carefully at the Mapping step, because a column pointed at the wrong field fails consistently rather than occasionally.

Common questions

Do failed rows partially import?

No. A row either imports completely or not at all, so you never end up with half a customer.

Where is the error report?

Open Import Data, open the import and download it from there. It is named after the import, like import-42-errors.csv.

Can I just fix them by hand in Youzse?

For a handful, yes, that is quicker. For more than about twenty, fixing the spreadsheet and re-importing is faster and less error-prone.
