Excel for Microsoft 365 Excel for the web

Important: Agent Mode in Excel is available in Excel for the web with a commercial Microsoft 365 Copilot license or a Microsoft 365 Premium subscription. It is not yet available to customers in the EU. Agent Mode in Excel for Windows is currently only available in the Insiders Beta Channel as Agent Mode (Frontier). Note that this feature is being gradually released over the next few weeks. You may not be able to use this feature yet. 

Agent Mode lets you build and edit workbooks side by side with Copilot. When you're updating budgets, creating financial models, or analyzing data, Agent Mode uses Excel's most powerful tools like tables, charts, PivotTables, and formulas to help you get the job done. 

Agent Mode updates your workbook using Excel's built-in features, so your content stays editable and synced with the latest changes. You're in control of everything that's modified—at any time.

Agent Mode is best for complex, multi-step tasks like reshaping data, merging sheets, or building reports with multiple elements. Note that for complex requests, Agent Mode may take a few minutes to generate an initial response and refine it, while it's running, you’ll see its reasoning in the pane. For conversational help and tasks that don’t change your workbook, M365 Copilot Chat may be a better choice. For simple, one-step tasks—like inserting a single chart or PivotTable—Excel’s Recommended Charts and Recommended PivotTables may be faster.
