How to read .sav files or save to txt using blueprints?

I need to get info. from the .sav files that ue4 creates when you save the game, but I am having problems opening them in my PC. What I need is, for example, I have a blueprint to save whether the player hit a right or a left target, and I would need to open the .sav file and access that info directly so I can export it to another program.

Do you think there would be a way to access that info. or should I try to change the file in which ue4 saves data?, this being used for a research project.

Thank you
