Microsoft has now integrated Copilot AI into Word, Excel, PowerPoint, and other Office applications. Copilot is enabled by default in Office applications for us to use and experience immediately for the content you are editing or processing. If you do not like the Copilot icon displayed in the Office application interface, you can turn it off, according to the instructions below.

How to Turn Off Copilot in Excel and PowerPoint
For Excel and PowerPoint, there is currently no option like there is for Word, so you need to completely disable Copilot for all Office applications.
Step 1:
Open Excel or PowerPoint then click on File . Continue to click on Account in the lower left corner and look to the side and select Manage Settings .

Step 2:
Switch to the new interface, users scroll down below at All connected experiences , you uncheck Turn on all connected experiences to turn off all services connected to your Office account.
