This will repair the entire Office suite even if it's just one application you want to repair such as Word or Excel. If you have a standalone app installed, then search for that application by name.

iii. In the window How would you like to repair your Microsoft 365 and Office Programs, select Online Repair > Repair to make sure everything gets fixed. (The faster Quick Repair option is also available, but it only detects and then replaces corrupted files.)
