Import Troubleshooting

If an import fails or results look incomplete, use this checklist to diagnose the issue fast.

Top causes

  • Missing required columns: Ensure your file includes expected headers for your source format.
  • Unmatched cards: Some rows may not map because of set code, collector number, or card-name differences.
  • Unsupported formatting: Extra separators, unusual quote usage, or modified templates can break parsing.
  • Platform export mismatch: Make sure your export format matches the platform instructions in the import guide.

Quick fix workflow

  1. Re-export from the source platform without manual edits.
  2. Run a small test import (10-20 rows) to isolate formatting issues.
  3. Review the import summary and export unmatched rows for inspection.
  4. Fix row values for set code/collector number/card name, then retry.
