At some Chromium-based browser, click right top your username / All Boards / New Board / From Previous Export.
At input field, right click / Paste as Text.
Click Import.
By default a board's JSON export includes its attachments as base64 data. For very large boards this can overflow the JSON serializer, so there is an option to export the board's structure without the base64 attachment data:
GET /api/boards/:boardId/export?attachments=false
The board export menu has a matching Export / JSON (without attachments) entry.
The default export (no attachments=false) still includes the attachments.
sqlite3 wekan.db
.mode json
.load wekan-export-board.json board
