Is It Possible to Modify Files in .git repository of an experiment (.txt, .xlsx, .csv) via Javascript in Pavlovia?

Hi Mert, thanks for the hint! Sadly, this does not fix my problem. Would you be so kind to compare your code with what I posted here and tell me if there is anything obviously wrong with what I did? Thanks! Adrian

Edit: I fixed it now. I had to set the “scope” of the record to the specific experiment. “Designer” did not work.
