csvi - terminal CSV editor

CSVI is a terminal-based CSV editor for UNIX-like systems and Windows.

This is free and open source software.

Features include:

Minimal changes on save:
- CSVI keeps the original formatting for every unmodified cell: quotes, line endings (LF/CRLF), BOM, encoding, and field/record separators.
- Only actual edits are saved—making it ideal for clean diffs and safe edits to production data.
vi-style and Emacs-style keybindings – move the cursor like in vi, and edit cells like in Emacs.
Reads from both file and standard input – pipe CSV data into CSVI or open a file directly.
Fast startup and background loading – opens large files quickly without blocking the interface.
Visual feedback for edits – modified cells are underlined.
Shows original format details – the bottom line of the screen shows technical info: quoting, encoding, field separators, and more—just as they appeared in the original file.
Flexible encoding support:
- UTF-8 (default).
- UTF-16.
- Current Windows code page (auto-detected).
- Any encoding from the IANA registry using -iana NAME.
Color scheme options:
- Default colors assume a dark background.
- Use -rv for light backgrounds, or set NO_COLOR to disable color output.
