Trello exports a board as a JSON file, and LoopGantt reads that file as it is. Drop it into the Import Project dialog: each list becomes a phase and each card becomes a task. No conversion step is needed.
Trello vs. Gantt: a note on structure
Trello is a Kanban tool: it keeps cards in lists, without durations or dependencies. A Gantt chart needs both, so after the import you add two things Trello doesn't have:
- Durations. Every card arrives as a one-day task. Set how long each task really takes.
- Dependencies. Link the tasks that must finish before others can begin: see Task Dependencies Explained.
Step 1 — Export from Trello
- Open your Trello board.
- Open the board menu and choose Export as JSON (in the print and export options).
- Save the file with the
.jsonextension. If your browser shows the JSON as a page instead of downloading it, save that page as a.jsonfile.
Step 2 — Import into LoopGantt
- On your dashboard, click Import.
- Drop the JSON file into the Import Project dialog, or click to browse.
- The preview shows Detected: Trello Board Export, the number of tasks and the first tasks of the plan. The project takes the board's name; you can change it here.
- Click Import Project.
What comes across
| Trello | In LoopGantt |
|---|---|
| Board name and description | Project name and description |
| Each open list, in board order | A phase |
| Each open card, in list order | A one-day task in its list's phase |
| Card description | Task description |
| Due date | The task is placed on its due date |
| Due date marked complete | Status Completed, progress 100% |
| Color of the card's first label | Task color: the nearest LoopGantt color (sky becomes cyan, yellow amber, black gray) |
| Checklists | The task's checklist, with ticked items marked complete. When a card has several checklists, each item starts with its checklist's name. |
Archived lists and archived cards are left out.
What doesn't come across
- Dependencies and durations (Trello has neither; the preview reminds you).
- Members, label names, comments, attachments and custom fields.
Limits: the file can be up to 15 MB and the plan up to 5,000 tasks. Importing always creates a new project, which counts toward your plan's project limit; it never merges into an existing project.
