Henceforth you can Open Microsoft Office files directly in Chrome on Windows and Mac.

It is good news for the users of Windows and Mac who henceforth can enjoy the possibility to open Microsoft Office files via the Chrome Browser.
This means run Chrome Beta on Windows or Mac and install the Chrome Office Viewer (Beta) extension, click a link to an Office
file and open it directly in Chrome.
The Chrome Office Viewer can also protect you against malware delivered via Office files, web pages and PDFs. The Chrome developers announce having added a specialized sandbox to impede attackers who use compromised Office files to try to steal private information or monitor your activities.
