Build a real, formula-driven Excel (.xlsx) model — not a static table. Use when asked to build an Excel model, a financial model, a budget/forecast spreadsheet, or any .xlsx with live formulas a user can edit. Produces an actual .xlsx file via a generated openpyxl script: an inputs/assumptions sheet, calculation sheets with real cell formulas, and formatting — so changing an input recalculates the model. Requires a code-execution environment (Claude Code, the API code tool, or Claude.ai).

# Excel Model Skill

A model is only useful if it's *live* — change an assumption and everything recalculates. A markdown
table can't do that; a real `.xlsx` with cell formulas can. This skill builds an actual Excel workbook by
**writing and running an `openpyxl` script**: a clean inputs sheet, calculation sheets that reference
those inputs with real `=` formulas, and sensible formatting — so the user gets a file they can drive,
not a snapshot.

> **Environment:** this produces a binary file, so it needs a place to run code — **Claude Code**, the
> **Anthropic API code-execution tool**, or **Claude.ai** (with the analysis/code tool). In the
> browser playground (no code execution), use the markdown output as the spec instead.
