New Chrome Beta extension by Google lets you view Office files directly in the browser

Google brings a speedy, more secure way to view Microsoft Office files directly in Chrome to Windows and Mac Pc
If you use a Chromebook, you’ve already been enjoying the ability to open Microsoft Word, Excel, and PowerPoint files directly in your browser. Starting today, we’re excited to bring this same functionality to Chrome on Windows and Mac.

If you’re running Chrome Beta on Windows or Mac and install the Chrome Office Viewer (Beta) extension, you’ll be able to click a link to an Office file and open it directly in Chrome.

In addition to saving you time, the Chrome Office Viewer also protects you from malware delivered via Office files. Just like with web pages and PDFs, we’ve added a specialized sandbox to impede attackers who use compromised Office files to try to steal private information or monitor your activities.

To give it a try on Windows or Mac:

    Get Chrome Beta
    Install the Chrome Office Viewer (Beta) extension
    Start clicking your favorite Word docs, Excel spreadsheets, and PowerPoint slides on the web

Since this extension is still in beta, we’d love to get your feedback. When you find issues, please click the “Report an issue” button while viewing the file to report a bug.
