From MS Project to OpenProj: Alternative Tools for Opening MPP Files

Have you ever received a file with the .mpp extension and wondered how to open it? MPP files are commonly associated with Microsoft Project, a popular project management software. However, if you don’t have access to Microsoft Project or simply prefer an alternative tool, there are several options available. In this article, we will explore some alternative tools that can help you open and view MPP files.

OpenProj: A Free and Open-Source Solution

One of the most well-known alternatives to Microsoft Project is OpenProj. As the name suggests, OpenProj is an open-source project management tool that offers compatibility with MPP files. It provides a user-friendly interface and many of the features found in Microsoft Project.

OpenProj allows you to import and export MPP files seamlessly, making it a suitable choice for users who need to collaborate with others using Microsoft Project. Additionally, it supports various operating systems including Windows, macOS, and Linux.

LibreOffice Calc: A Spreadsheet-Based Approach

If you’re looking for a different approach to opening MPP files without installing specialized software, consider using LibreOffice Calc. Although primarily known as a spreadsheet application, LibreOffice Calc can also handle certain project management tasks.

To open an MPP file in LibreOffice Calc, you need to convert it into a compatible format such as XML or MPX. Once converted, you can import the file into Calc and view its contents in spreadsheet form. While this method may not provide all the functionality of dedicated project management tools like Microsoft Project or OpenProj, it can be handy for quick review or basic editing needs.


GanttProject: Simple and Intuitive

For users looking for a lightweight yet effective solution for opening MPP files, GanttProject is worth considering. This free and open-source project management tool offers compatibility with MPP files along with a simple and intuitive interface.

GanttProject allows you to import MPP files and view their contents in a Gantt chart format. You can also make basic modifications to the project schedule, such as adjusting task durations or dependencies. Although it may not have all the advanced features of Microsoft Project, GanttProject is suitable for users who require basic project management capabilities.


Online Conversion Tools: Quick and Convenient

If you only need to view the contents of an MPP file without making any edits, online conversion tools can be a quick and convenient option. These tools allow you to upload your MPP file to their platform, which will then convert it into a more accessible format such as PDF or XLS.

By converting the MPP file into a different format, you can easily open it using common software like Adobe Acrobat Reader or Microsoft Excel. While this method does not provide full project management functionality, it can be useful when you don’t have access to specialized software or prefer a more universal file format.


In conclusion, opening and viewing MPP files without Microsoft Project is possible with various alternative tools. Whether you choose OpenProj for its comprehensive features, LibreOffice Calc for its spreadsheet-based approach, GanttProject for its simplicity, or online conversion tools for quick viewing convenience, there are options available to suit your specific needs. Explore these alternatives and find the one that works best for you.
