It's weird but I think Visidata is the best spreadsheet software out there. "But", I hear you cry, "visidata is not a spreadsheet." I know, I know, that is what is weird about it.
I'll say it again, Visidata is one my favorite new CLI/TUI tools over the last few years. It makes it extremely easy to explore/modify structured data in the terminal.<p>In the 2.9.1 release, they added support for:
- window functions listing values from around the current row.
- XDG support for config files.
- new loaders for Apache Arrow (IPC and streaming) and parquet formats
- Ability to quickly browse zip files on the web.
- And even some support for Windows users. Though I usually think of this as mostly a *nix terminal based tool.<p>It can still load and view many different types of file formats like csv, usv, lsv, json, Excel.<p>Check out the tutorial and youtube videos.
