Copilot: Automate Excel & PowerPoint

Key insights

• Skills are reusable instruction sets that extend Copilot inside Microsoft 365, giving the AI domain-specific guidance so it follows set methods instead of reinventing steps each time.
  
• Custom skills let teams create, upload, and update their own guidance for Copilot in PowerPoint and Excel, so common tasks use the same rules and templates every time.
  
• Excel skills speed repeatable work: build or edit workbooks, generate formulas and summaries, query across sheets, and apply consistent output formats via a OneDrive skills folder.
  
• PowerPoint skills help generate and polish slides from notes, documents, or tables while applying brand rules and templates to keep decks consistent and editable.
  
• Reusable workflows store the method, not the answer—users pick built-in skills or add custom SKILL.md files so Copilot applies the same steps to new inputs.
  
• Automation without losing control improves speed and consistency: define skills to reduce repetition, protect brand standards, and let teams reuse proven workflows across projects.
