Computer and mobile users have a handful of options when it comes to viewing and editing Microsoft Office files online. Users who have a Microsoft account can use the Office Web Apps in SkyDrive to create, edit, and save Office docs, including Word, Excel, PowerPoint, and OneNote documents.

A number of free alternatives also around to view Office files online, without having to install the Office suite or any other program. Services such as Google Docs and View Docs Online are two of the best services around to edit and view docs. View Docs Online lets you even view a document from a URL without even downloading the file. A number of lesser known services are also there but many users hesitate to view documents online due to privacy concerns.

Users who would like to view Office Word, Excel, and PowerPoint files right in their web browsers and who trust the software giant Microsoft can now use a free service named Office Web Viewer to open and view Office documents in web browsers.

The best thing about the service is that you don’t need a Microsoft account to use this free service!
