Google is about to release Chrome 27, but before that happens the company is releasing a new companion extension, its name is Chrome Office Viewer. This is a brand new, 25MB extension that allows you to view Microsoft Office files in the popular web browser without the need to launch Office, and it works in Windows and Apple’s OS X.
The new app can open Microsoft Word (.doc/.docx), Excel(.xls/.xlsx), and PowerPoint (.ppt/.pptx), and according to the search giant, Chrome Office Viewer is a more secure environment to view your files and prevent malicious code to get into your system, because the extension uses “a specialized sandbox” to prevent attacks.
Although this is a new extension for Windows and OS X, Chrome Office Viewer isn’t totally new, Chromebook users had this functionality for a while now.
Keep in mind that Chrome Office Viewer is meant to open documents you find on the web, but you can easily configure the Chrome to open the files you have stored in your computer. To do that, just right-click the Chrome shortcut in your desktop or taskbar, select Properties and copy the Target path (e.g., “C:\Program Files (x86)\Google\Chrome\Application\chrome.exe”). Now find compatible document, right-click and from the menu choose Open with, select Choose default programs, then More options, scroll down and click Look for more apps in this PC, then paste the target path, and finally click Open.
