Microsoft Office alternative options for windows, linux and mac

As Microsoft Office 360 and 2016 is bit expensive for most users it is a good idea to go for open source alternatives.

Libre office is a good alternative and I have used libre office in my Mac and Ubuntu operating systems. Libre documents can open using MS office and vise-versa.

Open office is also a good  alternative software for MS office suit. I haven't use open office for long time but it is a reliable software to use in most platforms.
