[What and Why:]<\/b><\/p>\n

<\/p>\n

Beginning September 14, 2026, the =COPILOT<\/b> function in Microsoft Excel will no longer be available. This function is currently offered as a preview feature through the Insider and Frontier programs.<\/p>\n

<\/p>\n

Customers can continue using Copilot in Excel through the Copilot side pane, which provides many of the same AI-powered capabilities, including summarizing text, classifying data, generating content, and retrieving information from the web. This change helps streamline the Copilot experience within Excel while continuing to provide AI assistance through a supported interface.<\/p>\n
