Import JSON/CSV

Use the board button to import cards from a CSV or JSON file into the current Trello board.

1. Authorize Trello when prompted. The importer needs read and write access so it can read board lists, labels, and members, then create cards.
2. Upload or paste a JSON or CSV file.
3. Review the automatic field mapping and choose a default list.
4. Preview all rows, fix any errors, then import.
