Command-Line-Excel — running natively in your browser via WebAssembly
C spreadsheet engine (dependency graph, formulas, SUM/AVG/MIN/MAX/STDEV, scrolling) compiled with Emscripten — no server involved. Source

Formulas
Commands (raw)
Click a cell to select it, then use the top field to set its value or formula
(arithmetic like 3+4 or a reference like B1 also works).
The second field sends a raw command straight to the C engine, exactly like the
native CLI's stdin — try function calls, ranges, or scroll_to<cell>.
Only ten rows/columns are visible at a time, matching the original terminal UI;
scroll with the ▲▼◀▶ buttons or w/a/s/d in the command field. A div-by-zero
shows as ERR, same as the terminal version. Quitting is disabled here so the
sheet stays alive in your tab.
