How to open GPJ files

Did your computer fail to open a GPJ file? We explain what GPJ files are and recommend software that we know can open or convert your files.

What is a GPJ file?

GPJ files are jGRASP Project files, which you can read more about below.

The GPJ file extension indicates to your device which app can open the file. However, different apps may use the same file extension for different types of data. So a GPJ opener may not be able to open all kinds of GPJ files. In this case, though, we only know of one specific use.
