Excel Agent Mode reaches general availability across web, Windows, and Mac

Microsoft has made Excel Agent Mode generally available on Excel for the web, Windows, and Mac. Unlike the standard Copilot chat, Agent Mode acts as an autonomous assistant that takes a user-defined goal, breaks it into steps, and executes each step inside the workbook while validating results. The AI shows its reasoning in the chat pane as it creates worksheets, writes formulas, builds charts and PivotTables, and cleans data. Access requires a Microsoft 365 Copilot commercial license, though personal or family plans with AI credits also provide entry. The new capability lets power users generate complete dashboards from conversational prompts, accelerating data-analysis workflows.
