Terminal-based spreadsheets and wordprocessor?

As for command-line spreadsheet programs there are sc and oleo.

See:

• sc: the Venerable Spreadsheet Calculator
• GNU Oleo

SC-IM (formerly scim; based on SC) is the best command line spreadsheet right now. It compiles easily on OSX. You have to make one modification to the source code to fix the backspace key on OSX.

I would suggest visidata.

VisiData is an interactive multitool for tabular data. It combines the clarity of a spreadsheet, the efficiency of the terminal, and the power of Python, into a lightweight utility which can handle millions of rows with ease.
