Any good alternatives for MS Office at free of cost ?

There's a longer (and more detailed) article here: http://www.infoworld.com/d/applications/open-office-dilemma-openofficeorg-vs-libreoffice-716?page=0,0

I didn't know any of them before I started using Linux. The first time I installed Linux it came with the Open Office package. After I updated my PC and changed the OS to a newer Linux version that now uses Libre Office.

I have not come across libreoffice.org earlier and hence I recommended openoffice. If however libreoffice is better than openoffice then one can as well go in for libreoffice. good day.

hi ravisivan, thanks for the alternative for ms office,when we are using ms office,how can we use alternative open office, i think every computer must have ms office soft ware,so how to install it how to use them alternatively when ever we want to use ms office or open office, i hear that one more software that macintosh also there,what about that one,kinly explain about them,have a nice day

OpenOffice and LibreOffice can read and write Office 2003 format files. They are not fully compatible with MS Office 2007 and later XML formats (with the .docx, .xlsx extensions). As long as people using Office 2007 and later can be persuaded to save all their documents in the earlier format, there will be little problem with using the two packages side by side.

Yugasini: Openoffice is required in western countries where we are not supposed to use ms office. In India we do get MS Office installed easily and there may not be need for openoffice. I think having the two --MS Office and Open office may not be a problem but compatibility for opening of files opened in another version is to be seen. I did not experience any problem while using open office in PC. now i use only ms office in my laptop. I have not heard about macintosh. good day.
