Trello – Migrating Wunderlist to Trello

With the release of the Data Export feature, you can now

1. Go to your board
2. Click the "Board Menu" button (on the right-hand-side of the screen)
3. Select "Share, Print, and Export"
4. Click "JSON"

This will download a copy of your board data.

Pro tips:

• You can also just add .json (or /somename.json) to the end of a board or card URL, to get the prompt to save the downloaded file (e.g. https://trello.com/board/welcome-board/4e6a8095efa69909ba007382/somename.json)
• Alternatively, instead of clicking on the "JSON" button, you can right-click on it, and copy the URL
• If you have lots of boards that you want to download regularly, you'll have to save all the JSON links somewhere for all your boards, and download each one individually.
• Changing the names of all these individual files for each set of backups could get a little tedious, so one idea would be to create a new folder each time you backup your boards, and then save a set of exported files into that folder.

There isn't currently a way to import data, though it may be added in the future.
