Sheet
A collaborative spreadsheet — an Excel/Sheets-familiar grid with live multiuser editing (Yjs CRDT), formulas (~300 Excel-compatible functions), conditional formatting, data validation, named ranges, charts and comments. Python (Pyodide) and JavaScript run both as cell functions (=NAME(...)) and as code cells — output spills into the grid, or draws a matplotlib / interactive Plotly chart. Code runs in a sandboxed worker with a Stop control, and an agent command surface drives every edit. Opens .xlsx / .csv.
