I just sent 30 minutes with rowzero and pysheets. RowZero seems to support huge datasets. I have been using quadratichq as a python spreadsheet but now I think RowZero has more features (and a cheaper price point). I thought pysheet might be opensource but it seems to be closed and 2x the price and it is limited to 50 rows. Finally i was not able to figure out how to import https://www.w3resource.com/python-exercises/pandas/excel/Sal... into pysheets.

I didn't know about visidata this is incredible. Thanks everyone for the informative post.
