[Microsoft Excel's COPILOT Function to Cease Support on September 14] Deep Tide TechFlow reports that on August 15, Microsoft announced the COPILOT function in Excel will cease support on September 14. This feature allows users to describe their needs in natural language and call on Copilot to generate results. It was tested last August for Frontier and Insider users and was originally planned for release in January 2027. Microsoft decided to discontinue the function due to the presence of multiple interactive entry points like floating action buttons and sidebars in Copilot. Users are advised not to use this function for numerical calculations.
