This produces more consistent output, reduces rework, and gives users greater control over how Copilot edits spreadsheets.

This helps reduce the risk of external, third-party, or unreviewed information appearing in AI-generated content while still allowing users to work efficiently with trusted internal content. The capability applies to Microsoft 365 Copilot and to agents built in Copilot Studio, published to Microsoft 365 Copilot, and using only Microsoft 365 data.

Purview controls extend to CoworkRolled out in June
