sc is a cross-platform, free, TUI, spreadsheet and calculator application that runs on Unix and Unix-like operating systems. It has also been ported to Windows. It can be accessed through a terminal emulator, and has a simple interface and keyboard shortcuts resembling the key bindings of the Vim text editor. It can be used in a similar manner to other spreadsheet programs, e.g. for financial and budgeting purposes.

The program is based on the ncurses interface library, and has a rich manual page describing its options and configuration. It has a rich mathematical formula library and uses the same file format as Xspread, also supporting plugins as external commands. The program was previously known as vc.^[1] sc is already present in the default repositories of popular Linux distributions such as Ubuntu, Fedora, and Arch Linux.^[2]
