See 'What version of Office am I using?' if you don't know what version you're on.
If your version of Microsoft Office is older than Office 2016 v15.35, you’ll have to choose from a variety of costly or time consuming and complicated options. If you have Office 2016, you should. High Sierra leaves Microsoft Office for Mac 2011 behind, 2016 edition needs updating. Of applications from unreleased version 15.35 and later do work, users will still have to endure. Office 2019 for Mac was launched in September 2018 as an update to Office 2016 for Mac. However, some of the new features had already been available as part of the then-called Office 365 subscription. Office 2016 for Mac after v15.35 is also OK for Catalina. After v15.35, Office 2016 for Mac is 64-bit only. If you’ve been updating Mac Office 2016 regularly, you’ll be OK. Office 2011 for Mac will NOT work because it’s only 32-bit. Also support for Office 2011 ended in October 2017 so it’s really past time for a switch to either Office.
