Kimi Office Skills

Production-Proven Full OpenXML Open Source

Best for: Document automation pipelines that need production-quality XLSX, DOCX, and PDF output — native charts, data validation, and full OpenXML control proven at Kimi's scale

Not ideal for: Interactive or one-off use — Kimi Office Skills is a production automation skill, not a casual "make me a spreadsheet" tool; the API surface is more complex than simpler Excel MCP servers

Multi-Format Office Generation

Production-proven: These skills were extracted from Kimi's internal document generation pipeline — they handle the edge cases and format quirks that emerge at production scale, not just happy-path demos.

Key Capabilities

📊

Native Excel Charts

Charts embedded as native OpenXML chart objects — not images. Resizable, editable in Excel, with proper axis labels, legends, and data series

✅

Data Validation Rules

Set dropdown lists, number ranges, date constraints, and custom formula validation on cells — critical for forms and data entry templates

🔧

Full OpenXML Control

Direct access to OpenXML primitives — when you need specific behavior that higher-level libraries don't expose, the raw XML layer is accessible

🔄

Multi-Format in One Pipeline

Generate XLSX, DOCX, and PDF from the same data source in one skill invocation — ideal for report automation that needs multiple output formats

Architecture deeper than any other skill in this collection: kimi-docx uses C#/.NET 8 + DocumentFormat.OpenXml (Microsoft's official SDK) for DOCX generation — the closest thing to native Office output possible. kimi-xlsx uses a pre-compiled binary; kimi-pdf uses Node.js + Playwright/Chromium. Setup is the most complex tested: three separate tech stacks, no root-level requirements.txt (despite what was previously shown). docx init auto-installs .NET SDK (~200MB) if missing. Documentation scores slightly higher: error mapping system and bash help text show developer experience consideration.
