What is a GAN file?
A .GAN file is a GanttProject Project File. It is a project management document created by GanttProject. The file contains tasks, milestones, resource assignments, and project dependencies. .GAN files store this project data using the standard XML format.
How to open GAN files?
The primary software to open these files is GanttProject. This software is free and works on Windows, macOS, and Linux. Because the data is saved as XML, you can also open a .GAN file with text editors like Notepad++ or Visual Studio Code to read the raw project code.
Software and tools
If you need to share a project plan, GanttProject allows you to export .GAN data to .PDF, .PNG, or .CSV formats. You can also export the plan as a Microsoft Project XML file for users who rely on Microsoft Project.
Inspecting files with viewer.online
viewer.online/gan analyzes .GAN files to identify their exact format and creator software, shows which programs can open the file, and usually previews it. File extensions can sometimes have multiple possible meanings. If this happens, viewer.online/gan will help identify the actual format of your specific file.
Summary
Because .GAN files use the known XML format, viewer.online/gan can safely open and display them online, eliminating compatibility problems.
