Spreadsheet

Spreadsheet is a real spreadsheet: a 52 column by 200 row grid per sheet, multiple named sheets in one persisted workbook, and a hand-written formula tokenizer, parser and evaluator behind it.

Formulas recompute through a live dependency graph, not string matching tricks, and the whole workbook imports and exports as CSV.

Type a formula referencing another cell and the grid recalculates every dependent cell the moment the value it depends on changes, the same way a desktop spreadsheet does.

Multiple sheets live in one workbook, each with its own name, and the whole thing exports to CSV and imports right back in, so your data is never locked inside the browser tab.
