I remember seeing somebody getting Lotus 1-2-3 resurrected somehow. And I know there is a spreadsheet implementation for Emacs. But I’ve not tried either.
For more mundane tasks I’d say Libre Calc would be good enough – and I hardly use it, either. I think my main issue is that I’d like a command line spreadsheet thing that’s not very functional but a bit like bc or dc or orpie – a thing that starts up super quick, let’s me keep state, and all that.
