TaskJuggler as a Linux alternative to Microsoft Planner
Updated
Our verdict
TaskJuggler is not a good replacement for Microsoft Planner. It is a text‑based, command‑line project‑management engine that outputs static HTML reports; it lacks a kanban board, real‑time collaboration, and file‑storage integration. It may suit experienced project managers who prefer scripting and detailed resource allocation, but it does not match Planner’s simple, web‑based, team‑friendly interface.

What works the same
- Both are project‑management tools that can be used on Linux
- Both can be run on Windows as well
- Both allow setting due dates and priorities for tasks
What is different
- TaskJuggler uses a text definition file, Planner uses a web UI
- Planner provides a kanban board, TaskJuggler generates static HTML reports
- Planner integrates with Microsoft 365 files, TaskJuggler has no built‑in file‑storage integration
- Planner supports real‑time collaboration, TaskJuggler does not
- Planner is cloud‑based, TaskJuggler is a desktop tool
Opening your Microsoft Planner files
Microsoft Planner data is stored in Microsoft 365’s proprietary format and is not exportable to a plain text or XML format that TaskJuggler can read. There is no known direct import path; you would need to export tasks manually to a CSV or JSON and then write a custom parser to create a TaskJuggler project file.
Switching from Microsoft Planner to TaskJuggler, step by step
- Export Planner tasks to CSV from the Planner web interface.
- Open the CSV in a spreadsheet editor and clean up columns (task name, due date, priority, assignee).
- Create a TaskJuggler project file (.tjp) and define resources for each team member.
- Map each task to a TaskJuggler activity, setting start/end dates, priority, and resource assignments.
- Run the TaskJuggler command line engine to generate an HTML report.
- Share the report with the team and update the .tjp file as tasks change.
