Microsoft Turns Copilot Into an In‑Document Agent for Word, Excel and PowerPoint

The upgrade moves Copilot from chat to direct edits with review tools for oversight.

Overview

  • Microsoft made the agent version of Copilot generally available in Word, Excel and PowerPoint for Microsoft 365 Copilot subscribers, with rollout starting now.
  • Copilot can now take actions inside files, making live edits and running multi‑step tasks instead of only offering sidebar suggestions.
  • Excel gains automation that can analyze datasets, spot anomalies, generate multi‑sheet reports and refresh forecasts with little setup.
  • In Word and PowerPoint, Copilot can pull from emails, Teams transcripts, SharePoint and OneDrive to draft structured proposals and build brand‑compliant presentations.
  • Microsoft shows what Copilot is doing and lets users review changes, yet the feature appears by default via a prominent prompt and critics and early tests flag reliability issues that still need human checks.
