The open source vim-like spreadsheet program sc-im is wonderful to work with. If you use Vim regularly, it quickly becomes intuitive.
sc-im is entirely viable as a LibreOffice Calc or Microsoft Office Excel alternative in the terminal. It even supports embedded Lua scripting. It's a one-man passion project that really needs more hands.
