I am using Excel online (through Teams and OneDrive) and want to remove the autofill of cells. I can't seem to figure out how to do this as every help page relates to solving this problem using the "options" tab, which isn't available through Excel online. Any help would be greatly appreciated.
For Excel Online there is no Options as in desktop version, i.e. you can't set them for the application and/or entire workbook. You may only play with settings for some elements as Charts, PivotTables, etc.
