15 years ago I went on a 3 month Semester at Sea study trip on a small cruise ship circumnavigating the globe.

There was only a handful of whitelisted sites available on the WiFi, otherwise you would need to pay a ton for the satellite connection or … have a staff password.

At least with my group we had a a healthy list of credentials that had been acquired in various ways. Even with occasional password changes, we managed to stay connected.

Already bailed when they blocked account sharing…

Extra scary when there’s a power outage and your screen isn’t backlit 😱

You might also find the Python library pandas useful. Its “DataFrames” can mirror your excel data 1:1 and you have convenience methods like to_excel(). Easy to combine with numpy for performant matrix math.

XLSX just becomes a container for storing/sharing your data, and while Python is used for analysis. I would use matplotlib for plotting rather than embedding in the sheet.

If I’m doing anything substantial, calculation-wise, I use openpyxl.

Agreed. I really tried to like Libre/OpenOffice over the years but it never felt right. OnlyOffice really hits the spot for me.

I don’t use Windows much any more but I was happy with the discounted student version of Office 2016, afaik the last perpetual license.

I like the design but ultimately prefer a backpack.
