# Excel Spreadsheet Workflows > Tech Stack Target / Version: Excel desktop or `openpyxl`-based spreadsheet automation with current OOXML-compatible workflows. Use this skill when the deliverable is an `.xlsx` workbook or when spreadsheet structure matters. - Leverage native parallel subagent dispatch and 200k+ context windows where available. ## Current MCP Reality Excel MCP tooling is host-dependent. In GitHub Copilot, Excel actions may appear as grouped Office tools. In Codex or Claude, those tools may be absent entirely. Treat the included Python script as the reliable fallback. ## Activation Conditions Use symptom -> action triggers: when one matches, apply this skill and verify with the protocol below. - Creating or updating workbooks - Converting CSV data into structured Excel output - Applying formulas, formatting, charts, or pivots - Producing spreadsheet deliverables when layout matters ## Practical Workflow 1. Confirm whether the client exposes spreadsheet MCP tools. 2. If yes, inspect the actual tool names before assuming a wrapper exists. 3. If no, use the local converter or author the workbook with `openpyxl`. 4. Validate formulas and chart ranges before claiming the workbook is ready. ## MCP Fallback – Native Automation When MCP is unavailable, use native automation: `openpyxl` for `.xlsx`, CSV export for flat data, and manual formula inspection for high-risk calculations. Preserve formulas, number formats, sheet names, hidden sheets, and workbook m
