Your tag line says that you have a MacBook Air running Monterey.

You cannot upgrade past Monterey unless that MacBook Air has a hardware model year of 2018 or later.

• If it is from 2018 or 2019, you can upgrade to Ventura or Sonoma.
• If it is from 2020 or later – whether it is a 2020 Intel model or has a M-series chip – you can upgrade to Ventura, Sonoma, or Sequoia (the current version of macOS).

How to download and install macOS - Apple Support

Since you would be paying for Microsoft Office 365 (if you could upgrade to Ventura) anyway, why not pay less for SoftMaker's Office 2024/NX which has clones of Word (TextMaker), Excel (PlanMaker), and Powerpoint (Presentations). Office 2024/NX has a free trial and different payment options for a formally supported application suite. It opens MS Office documents in their native document format with the familiar ribbon bar interface.

Although you will see others suggest the free LibreOffice Suite which has reasonably good MS Office clone work and document compatibility, it will take some learning curve to adapt from MS Office to LibreOffice. To ease that transition, some detailed documentation is available that has been written in LibreOffice Writer.

Either of these application suites will work just fine on macOS Monterey (or later).
