GanttProject as a Linux alternative to Microsoft Project
Updated
Our verdict
GanttProject can replace Microsoft Project for small‑to‑medium teams that need basic Gantt charting, task dependencies, and resource tracking without a budget. It covers core scheduling and workload analysis, but it lacks advanced cost management, detailed reporting, and enterprise‑level integration. Users who only need free, cross‑platform scheduling will find it sufficient; larger organizations relying on Microsoft Project’s budgeting, resource leveling, and API hooks will need a more feature‑rich solution.

Opening your Microsoft Project files
GanttProject can open and export projects in its own XML format, but it does not natively read or write Microsoft Project’s .mpp files. Users must convert .mpp files to XML (or CSV) via third‑party tools before importing into GanttProject, and exported XML cannot be directly opened in Microsoft Project without conversion.
Switching from Microsoft Project to GanttProject, step by step
- Export the Microsoft Project file to XML or CSV using the export function in Microsoft Project.
- Open the exported file in GanttProject and verify that tasks, dependencies, and resources appear correctly.
- Adjust any missing fields (e.g., budgets or custom fields) that GanttProject does not support.
- Save the project in GanttProject’s XML format for future editing.
- Generate PDF or HTML reports if needed for stakeholders.
- Re‑import the GanttProject XML into Microsoft Project if a round‑trip is required, using a conversion tool.”
