sc-im - Spreadsheet Calculator Improvised -- An ncurses spreadsheet program for terminal

Project mention: Csvlens: Command line CSV file viewer. Like less but made for CSV | news.ycombinator.com | 2024-01-06

While not built around CSV, two terminal spreadsheet tools I have successfully used in the past are sc-im and the (neo)vim plugin vim-table-mode:

https://github.com/dhruvasagar/vim-table-mode
Back then I stopped using sc-im because it could not import/export XLSX, if I remember correctly. Apparently it can today!
vim-table-mode always felt a little fragile and I don't want to be bound to vim anymore. That said, it still feels like a small miracle to me to have functional spreadsheet formulas inside markdown documents – calculation and typesetting all in one place.
