I've been getting a pop up warning that my spreadsheet has too many custom styles (over 3000) and it is slowing performance.
My company has "helpfully" installed Copilot AI to help everyone do their jobs.
So I ask it, "Can Copilot delete unused custom styles?"
Copilot says, "I can only work with spreadsheets that have autosave enabled."
OK, enable autosave.
"Can Copilot delete unused custom styles?"
It says, "Yes, Copilot can delete unused custom styles if you ask it to."
Huh. "Delete unused custom styles." It spins about 15 seconds.
It says, "Copilot cannot delete unused custom styles. I can 1) show you how to delete them manually or 2) provide you with VBA code to delete the styles."
I click on option 2. It spins for 15 seconds.
"Copilot cannot provide you with VBA code to perform that action. Would you like to see how to delete them manually?"
So I turned autosave back off.
