Copilot in Excel now works in cloud-saved workbooks with AutoSave turned off on Windows and Mac; when there are unsaved changes Excel prompts to enable AutoSave first, but users can continue without it.
Why it matters: Removes the AutoSave-on prerequisite that previously blocked Copilot in otherwise-supported workbooks.

Users can attach a Power BI report from the work content selector and have Copilot in Excel analyze performance, spot trends, and build summaries against the report data while respecting existing row-level security.
Why it matters: Brings governed BI metrics into the Excel grid without exporting or reconciling data, and keeps row-level security intact.
