Newer operating systems will run older versions of Excel, but the newest
versions of Excel may not run on older operating systems. System
requirements are listed on the box.

As noted by others, Excel is not part of the operating system, and (with
the exception of a limited time trial version) must be purchased (as
either a separate product or part of Office), rather than downloaded.
