GanttProject as a Linux alternative to Microsoft Office Project
Updated
Our verdict
GanttProject can replace Microsoft Office Project for basic Gantt‑chart based planning and resource tracking, especially for small to medium projects. It offers task dependencies, milestones, WBS, and resource allocation, and can export reports to PDF or HTML. However, it lacks the advanced cost analysis, detailed dashboards, and full Microsoft Project file support that larger teams rely on. Users who need lightweight scheduling without the premium features will find it adequate.

- No built‑in dashboards or KPI widgets
- Limited WBS depth compared to Office Project
- No integration with other Microsoft Office tools
- No active development – project is discontinued
Opening your Microsoft Office Project files
GanttProject can import and export projects in XML format, but it does not support the proprietary .mpp files used by Microsoft Office Project. Users will need to convert .mpp files to XML (or use a third‑party converter) before opening them in GanttProject, and exported files will not be directly usable in Office Project without conversion.
Switching from Microsoft Office Project to GanttProject, step by step
- Export the Office Project file to XML or CSV using the built‑in export option or a third‑party converter.
- Open the converted XML file in GanttProject to review tasks, dependencies, and resources.
- Adjust any missing fields (e.g., cost data) that GanttProject does not import.
- Save the project in GanttProject’s native format for future edits.
- Export reports or PDFs as needed for stakeholders.
- Keep a backup of the original .mpp file in case you need to revert.
