Microsoft Excel's COPILOT function will no longer be supported on September 14.

Microsoft Excel's COPILOT function will cease support on September 14. This feature allows users to describe requirements in natural language and invoke Copilot to generate results. It was tested for Frontier and Insider users in August last year and was originally planned to launch in January 2027. Microsoft decided to deprecate it because Copilot already has multiple interaction entry points, such as floating action buttons and sidebars, and does not recommend users use this function for numerical calculations.
