LibreOffice
libreoffice{dot}org
It's a free, open source office suite (word processor, spreadsheet, presentation, database) that does everything MS Office can do. It runs identically on MacOS, Linux, and Windows. It can read/write MS Office files, plus the OpenDoc file standard. It can also export documents as PDF.
I have not had a need to run MS Office for several years and I don't miss it at all.
