Did you consider trying pyspread?

not really … I did play with pyspread some time ago tbh i was put off by the basic UI and rather childlike website (sorry I know that’s not really fair, but I am a human). I’ll definitely take a fresh look at it now you mentioned it. curious: what are the standout features of pyspread that you like?

oh and omasheet is Rust and uses Polars so I am working with that rather than NumPy SciPy
