Show HN: A terminal spreadsheet editor with Vim keybindings

Show HN: A terminal spreadsheet editor with Vim keybindings While speccing out this spreadsheet tool, I realized that I never had to think about the keybindings. It all just came naturally from Vim. Normal&#x2F;insert&#x2F;visual modes, hjkl navigation, dd&#x2F;yy&#x2F;p, :w, :q. The usual muscle memory works.<p>It supports CSV&#x2F;TSV import and export, and a native .cell format that preserves formulas. The formula engine handles SUM, AVERAGE, COUNT, MIN, MAX, and IF with range references.<p>The codebase is a Cargo workspace: a pure cell-sheet-core library (no TUI dependency) and a cell-sheet-tui crate on top of ratatui. Early days, but it&#x27;s usable.<p>To try it out: cargo install cell-sheet-tui<p>Feedback of any kind is greatly appreciated!
