7 Free and Portable Microsoft Office Alternatives for 2025

Let’s say you want to open some office documents such as spreadsheet on a cybercafe. If the cybercafe is using licensed software, you can be certain that you won’t find Microsoft Office installed on the computers because the license is just too expensive and mostly people go to cybercafe to play games, check emails and web browsing.

Or probably the Microsoft Office installed on your computer is unable to run and you urgently need to open a document file when you cannot get help at the moment to fix the problem. You are left with the choice of either to use some of the online cloud based office suites such as Google Docs, Windows Live Office, Zoho, ContactOffice or simply run any of these 5 portable free office suites directly from your USB flash drive.
