Convert .py to .psyexp

Does anyone know how to convert a .py file to .psyexp? I built an experiment in the builder but then made manual edits to the .py and now am unable to create the .psyexp file with this updated version. Relatively new to psychopy so any help would be most appreciated!

OS (e.g. Win10): macOS Big Sur
PsychoPy version (e.g. 1.84.x): Psychopy v 2021.2.2 (I’m having issues with the latest version)


AFAIK, it is a one-way street. Builder to py but not the other way around.

Best wishes Jens
