I have exported board from one account of trello. Now I want to import that same on other account. I can't see any option to import the board. How can I do that???
Trello export is for backup and your own analysis. It is not intended to be imported into another account. Rather, you should invite the other account to be a member of that board. If you need a completely new copy, you can sign in to the other account and copy the board using Copy Board.
