LocalSheet
Everything you type is stored only in this browser's localStorage — there is no account, no server database, and nothing is ever uploaded. Use Backup to download your workbook as a file (and Restore to load it on another machine).

While typing a formula you get function autocomplete (↑↓ + Tab to accept), colored highlights on every referenced range, and point mode — click or drag cells in the grid to insert their reference at the caret. Each sheet is 10,000 rows × 52 columns; the practical limit is your browser's ~5 MB localStorage quota.
Linking sheets & named ranges
Reference other sheets like Excel: =Growth!B2 or ='Sales Data'!F2:F25 (quote names with spaces). Renaming a sheet rewrites every formula that points at it.
Named ranges: select any range, type a name (e.g. Revenue) into the Name Box (left of the formula bar) and press Enter. Then use it anywhere: =SUM(Revenue). Typing an existing name in the Name Box jumps to it — try SalesRevenue in the sample workbook.
Visualizer
The Visualizer tab turns your sheets into dashboards — bar, line, area, pie, scatter, KPI and table visuals with aggregation, group-by, filters, sorting and Top N. The first row of a sheet is used as column headers. Dashboards are saved in this browser too.
Formulas
Start with =. Cell refs (A1, $B$2), ranges (A1:C10), operators + - * / ^ & % = <> < > and these functions:
