Online view of Words, Excels, Powerpoints, and so on, on my website [on hold]

I'm having a website which users need to read a lot of uploaded files(which other users upload) like Words, Excels, PowerPoint, etc.

I want to enable them a view of the file on the website. My wish is that they will not download the file and the view on my website will be enough.

I know there is WebApps of Sharepoint, but i want another solution.

Any ideas?

Thanks.
