Libre Office 7.2
I was reading that LibreOffice 7.2 is out and it has big speed improvements for opening very large spreadsheets. That is kind of a big deal because the slowness of Libre Calc at dealing with big spreadsheets like the voter file was always a major drag for me.
That said, since learning PANDAS going back to large spreadsheets seems kind of unnecessary, although I guess it’s nice to drag and drop certain things you want to glance through.
