I'm working towards a setup that is lightweight as possible. I've used Open and Libre offices before, I'm wondering can I do away with the suite entirely?

I could use md + pandoc to produce text documents which takes care of my main use case for office.

The only other thing I use office for is the occasional spreadsheet manipulation (auto-filling and basic math functions, tinkering with sums etc).

I'm not sure of a suitable stand-in for this.

Thoughts? No idea too crazy, bonus points if it works in a console, minus points for cloud services ;)

Best
