Professional Excel spreadsheet creation with a focus on aesthetics and data analysis. Use when creating spreadsheets for organizing, analyzing, and presenting structured data in a clear and professional format.

• Excel

Where it runs, and how to install it

Agent Skills are a format, not a product feature: a folder with a SKILL.md and whatever files it needs. Nothing inside one is model-specific.

Claude

Drop the skill folder into ~/.claude/skills/, or upload it in Settings → Capabilities. Claude loads it when the description matches what you asked for.

Claude Code

Same folder, per-project instead: .claude/skills/ inside the repository, so the skill travels with the work rather than with the machine.

Any agent that reads SKILL.md

A skill is a folder with a SKILL.md and whatever files it needs. Nothing in the format is model-specific, so a runtime that reads the file reads the skill.
