Is there a way to read ue4stats file without the session frontend?

I am curerently doing a project about game performance measurement. I need to do some analysis of the data, so I want to extract the data in the ue4stats file, converting the file into a txt or CSV file.

I researched for some days but still got no solution to my problem. So is there any way to do this? Or is there some ways to get data like the render time?
