Updated November 18, 2025: New capabilities are now available for Frontier program customers. We have updated the content below to provide additional details on how to use Agent Mode in Copilot in Excel.
[Introduction:]
Agent Mode in Microsoft 365 Copilot for Excel, available now on the web and Windows desktop, is a new way for users to work with Copilot in Excel. It uses natural language to build and edit workbooks and allows users to keep their content editable and stay up to date with the latest changes. Agent mode can search the web to pull in trusted, up-to-date information from the internet to complement your Excel data. It helps answer questions, provide context, and enrich your analysis without leaving your workbook. Agent Mode in Excel also supports working with Claude AI models from Anthropic to build workbooks directly in Excel.
Users stay in control over all modifications at any time. To learn more, read https://aka.ms/Agent_Mode.
