**[open-sheet.dev](https://open-sheet.dev)** — what it is, and what the file you hand over can do.

**The spreadsheet framework built for agents.** Describe the model you need in natural language — your coding agent writes the React. open-sheet handles the cell addressing, the formula references, the recalculation, and the export.

If [open-slide](https://github.com/1weiho/open-slide) is Google Slides for agents and [open-doc](https://github.com/simonliu-ai-product/open-doc) is Google Docs, open-sheet is **Google Sheets**. Same idea, different medium — but the medium changes the problem.

A deck is pixels. A document is pixels on paper. **A spreadsheet is a dependency graph.** A workbook baked down to static numbers is just a picture of a table. The value of a spreadsheet is that the person who receives it can change an assumption and watch it recalculate.
