Office Apps Online Viewer can display web hosted Office documents as a web page

Much like the almost killed Google Docs Viewer which can let you open popular file formats including Word, Excel & Powerpoint documents hosted on the web within the browser, the Office Apps Viewer can display Office document formats.

With Google Docs Viewer, you had to append the URL of a web hosted document as a value to the url field -
https://docs.google.com/viewer?url=http://research.google.com/archive/bigtable-osdi06.pdf

With the Office Apps Online Viewer, you similarly have to provide the URL of a web hosted document  as a value to the src field. I randomly picked some publicly available online Office documents to show examples. Click on the links below to see the Office Apps Online Viewer in action -

It has some limitations and not all documents may open. For instance, when I tried to open a PPT file that more than 10MB, it complained - "The file specified is larger than what the Office Online Viewers are configured to support."
