Trello CSV Card Importer preview

A free Trello Power-Up that bulk-creates cards from a CSV file. It adds an Import CSV button to any board — pick a target list, upload a CSV, map columns to card fields (name, description, due date, labels), and import every row in one click.

The Import CSV button installed in a Trello board's toolbar, next to Trello's own automation and filter controls
Installed as a normal board action — no separate app to open

Label matching and creation happen automatically, a preview table shows exactly what will be created before you commit, and the theming follows Trello’s own light/dark mode.

The importer's column mapping step, showing CSV columns mapped to card name, description, and labels, with a preview table of 42 cards ready to import
Column mapping and a full preview before a single card is created

Features

  • One-click CSV import with column-to-field mapping (name, description, due date, labels)
  • Automatic label matching and creation
  • Detailed preview table before import
  • Light/dark theming that follows Trello
  • No backend — CSV parsing runs entirely in the browser, so card data never leaves the user’s session
