Excel desktop and web client are still a mess. One of the more common use cases IMO is nothing more than a table with filtering applied. That DOES NOT WORK with Excel under their Office 365 (now Microsoft 365) offering. Data simply won't match up and can easily be lost upon modification where what you see is NOT what you get. For that single reason I dread M365. *It has been like that for over two years and counting, multiple documents and less than a hundred rows and a handful of users.
