Card JSON Saver for Trello® by Ceegor

Trello® is a registered trademark. This extension is not affiliated with, associated with, authorized by, endorsed by, or in any way officially connected with Trello, Inc. or Atlassian.

Save Trello® cards as JSON files, either one at a time or in a batch from a board.

For one card, open the card, click the extension button, and select Save card.

For a board, open the extension, enable Multiple selection, and let the board reload. A small unlabeled checkbox appears on each visible card preview. Select any cards, reopen the extension, and choose Save selected cards. Selected cards are exported sequentially.

Turning multiple selection off reloads the board and removes both the checkboxes and the selection.

After a fully successful batch export, checkboxes and multiple selection are removed by default. When Keep after download is enabled in the popup, they remain active.

The extension uses the existing Trello sign-in in the browser. Card data never leaves the browser except for the direct request to Trello needed to retrieve the requested JSON. There is no telemetry, tracking, advertising, developer-operated server, API key, or permission for arbitrary websites. Access is limited to trello.com and www.trello.com.
