Free (open source) alternative to MS Office.
I've used Apache OpenOffice for many years on Mac without any problems. There are free versions for Windows 7, 8, 8.1, XP, etc.
AOO component programs are 'Writer', 'Calc', 'Impress', 'Draw', Base' and 'Math'. These directly parallel MS Office component programs e.g. Excel, Powerpoint etc.
I believe AOO will do everything that MS Office can do AND there is a free forum that users can ask any questions about using AOO on various platforms. To my knowledge, AOO will
open all MS file formats (.xls, .doc etc.) and will save files in those (and other) formats to allow full cross-software accessibility.
One point I make is that the AOO download should be taken from the Apache home site to ensure all components etc. are included and no adware etc. in secretly included in the download, such as apparently occurs with a download from CNET among others.
Visit <https://www.openoffice.org/> and investigate yourself.
Why pay for MS software when an equivalent or superior program is available for free.
Hope this is helpful.
