Import from Trello to Kanban Zone
From your Trello account, export your board and cards to a .json format.
From within Kanban Zone, choose your board picker at the top left and click the ‘Add Board‘ button.
If you belong to more than one organization, choose which organization you would like to import your Trello board and cards to, otherwise proceed to the next step.
Choose the ‘Import from Trello’ option.
From the file picker, choose the Trello .json file you exported in step 1. Your Trello board will be created and the cards will be added to the matching board columns. During the import process, you will see a progress bar. The progress bar will disappear once the board and all its cards are available.
You can continue to work in Kanban Zone while your Trello board and cards are being imported.
