Quick answer

Copper imports fail on mismatched fields, bad cells, wrong import order or assignee names that do not match. Fix cells, import in the right order, or revert and retry.

Most likely fix: Fix cell errors before submitting

How to fix it

Try these in order — the most common fix is first.

  1. 1. Fix cell errors before submitting

    1. During import click Fix on each flagged cell
    2. Check field mapping on the mapping screen
    Did this fix it?
  2. 2. Import in the right order

    1. Import Companies first, then People, then Opportunities
    Did this fix it?
  3. 3. Match assignees exactly

    1. Use the name exactly as it appears in your Copper account
    Did this fix it?
  4. 4. Revert and retry

    1. Go to System Settings > Import Data and revert the import
    2. Wait up to 10 minutes before re-importing
    Did this fix it?
