I'm trying to install office on my macbook air 2015 with high sierra 10.13.6 but it all the install packages require os 10.4. How can I upgrade my os to 10.4? my software update says it's up todate.

The keyword is upgraded, not update. An upgrade will take you from High Sierra to Mojave by following the hardware requirements in the How to get old versions of macOS.

Look into the Free LibreOffice, it handles MS Office files like Word & Excel…
