Import Validation Messages & Troubleshooting
Overview
This page lists every validation rule Import Cards checks, and the exact message you'll see if a row or file doesn't pass — useful for working out why a particular row ended up in your Error Report.
File-level validation
No supplier selected → the Upload button stays disabled.
No file selected → the Upload button stays disabled.
File isn't a CSV → "File must be a CSV file"
CSV headers don't match the supported import format → "Invalid file format: unrecognised column headers"
Row-level validation
Duplicate row handling
If the same card_number appears more than once in a file for the same supplier:
Neither occurrence is processed.
Both appear in the Error Report and Results CSV with: "Duplicate row — this card_number appears more than once in the file."
Permission-related skips
Import Cards checks whether you hold Cards:Create and Cards:Update. If rows are found for an action you're not permitted to perform:
The validation summary tells you the count and reason alongside the overall record summary.
Those rows are classified as Skipped — missing create permission or Skipped — missing update permission.
You can still proceed with the rows you are authorised for.
Skipped rows appear in the Results CSV with their skip reason.
