CSV Import Robustness Update

Background

The user provided a specific CSV format associated with typical automated imports. The requirement was to extract relevant information (Quantity, Name, Finish, Scryfall ID) while ignoring other fields (such as Condition, Date Added, etc.).

Changes

  • Refactored src/client/src/services/CardParserService.ts to implement dynamic header parsing.
  • The parse method now:
    • Detects if the first line is a CSV header containing "Quantity" and "Name".
    • Maps columns to indices based on the header.
    • Specifically looks for Quantity, Name, Finish, and Scryfall ID (checking common variations like 'scryfall_id', 'id', 'uuid').
    • Uses strictly mapped columns if a header is detected, ensuring other fields are ignored as requested.
    • Falls back gracefully to previous generic parsing logic if no matching header is found, preserving backward compatibility with Arena/MTGO exports and simple lists.

Verification

  • Verified manually via a test script that the provided CSV content parses correctly into the CardIdentifier memory structure.
  • The extraction correctly identifies Quantity, Name, Finish (Normal/Foil), and Scryfall UUID.

Next Steps

  • Ensure the frontend CubeManager works seamlessly with this update (no changes needed there as it uses the service).
