Exporting data from Trello
All board members can export a board to raw JSON format. JSON format is not easily read by humans, but lends itself well to technical use. Boards in Premium Workspaces can be exported to CSV format, which can be opened in any spreadsheet program. It is not currently possible to import JSON or CSV formats to re-create a Trello board.
Board export options are available under Menu > More > Print and Export.
For more information about how to read Trello's JSON export, please see Making Sense of Trello's JSON Export.
Export all boards within a Workspace
With Trello Premium, you can export all the boards in your Workspace in both CSV and JSON format. You can create a new export, or review previous exports from the Export tab in your Workspace overview:
If you want to download all attachments from your workspace, check the "Include raw attachments" checkbox before creating your export. Attachments will be included in their original formats within a ZIP file in your download.
Please note that you'll need to be a Workspace admin to access the "Export" tab. See trello.com/premium to learn more.
Export to Excel / Spreadsheets
With Trello Premium, you can export information from your board in .CSV format, which can be opened in spreadsheet applications like Excel. Each user in a Premium Workspace (not including guests) has the ability to export the board as a CSV.
Personal Data Export
In addition to the above, you can also export your personal data. We have another article for that that you can find here.
