BUY Office OR use Open Office...its free...
All the best Brett
I recommand you libreoffice, it as almost all of the features of Microsoft Office and it's free:https://www.libreoffice.org/
I second their recommendation if you don't have the finances for M$ Office (which most don't). Libre Office is a great substitute because the functionality of the suite is almost identical to Office and it even opens M$ Office formatted software programs. You can find the latest version HERE
