hi @Alba10 sorry for having kept you waiting so long. I needed to think about how to handle this feature.

After some consideration I think the contribution would fit the form of a tutorial notebook best.

There you could detail what you need to do in psychopy to get the csvs and how to use pymovements.gaze.from_csv() to load these files. A dedicated pymovements.gaze.from_psychopy_csv() wouldn't be necessary then.

Would you mind to prepare a first draft for such a jupyter notebook tutorial? It doesn't need to have many details, but it should include how you created the data files and how you specified the columns in psychopy and pymovements.gaze.from_csv.
