2 Free Alternative of MS-Office
As you already MS-Office is not free software. You have to purchase the MS-Office package to use MS-Word, MS-Excel, and MS-PowerPoint.
So for that, I have searched and found the two alternatives to MS-Office, and they are totally free. They are:

It is totally free Office software. You can download and install it for free. You will get Text Maker, PlanMaker, and Presentation as an alternative to MS-Word, MS-Excel, and MS-PowerPoint.
