You must be referring to MacOS not iOS. What year is your Mac? Microsoft Office is not supported on older Macs and older Macs do not support the newer MacOS.

iOS only runs on mobile devices such as iPhone and iPad.

It is too old. Here is an article explaining Microsoft Office Compatibility:

Install FreeOffice. It has an excellent Excel-like spreadsheet app.
