Seemlessly integrating spreadsheets into jupyter sounds like the holy grail to me. I haven't tried it yet, though.

I think their users are people like me - who work a lot in Jupyter and swear by it - in a Python data analysis/visualisation environment. To bring in the best of spreadsheets into that could be magical. To just work in libreoffice calc or Excel would be a nonstarter, it just doesn't match all the other python tools in the workflow.

Mito isn’t just a spreadsheet that works with Python, but a spreadsheet that allows you to generate Python code when you edit!

If your just looking to work with spreadsheets with Python, I’d also reccomend checking out XLWings - I haven’t used it myself but some of our users do and love it!
