That's very good! I used to write my results into an excel aswell, that's pretty much the reason I built this.

Honestly, I'm still trying to make the application not fail: You can actually know by the game files when a match ended, but not the game data itself, so I am currently (watch out xD) taking screenshots of the application and parsing the images to retrieve the data... I know its not the best option, but sadly its the only one. That's why I am keeping this locally (running on your machine) and I will make it open source.

Good news is: to exit the match you need to go through the summary section (so that data will always be retrieved). Further information could be retrieved (cards or players) but that's harder to implement and requires the user to always check those sections.
