Back up your data, check your applications for compatibility, click here, and depending on which Mac model you have, then on the download link for Catalina, Big Sur, or Monterey; it needs to be at least a 2012 one(2013 for desktop Mac Pros) to run any of them. If you get a Mac App Store preview page, change the https at the beginning of its address to macappstore.
Catalina and newer won't run 32-bit software; download and use Go64 as well as using the first link above.
Alternatively, use a product such as LibreOffice instead.
