Excel AddIn but with Open Calc

Hi! :smiley:
I’ve tried to install StudioX and prepare it with instruction from RPA Starter. But I don’t have Excel on my computer so I can’t instal Excel AddIn. I was searching any solution in other topics but I found only information from 2018 that UiPath doesn’t support Open Office.

Is Excel AddIn required to learn? Can I use something else and how I could do it?
I know it’s easy but I’m totally newbie.
