With Google Drive you can keep all your important files in one place, then open them with your choice of apps and devices. Today, we’re offering new ways to work together with Office files, using the Google Drive plug-in for Microsoft Office.
With the new Google Drive plug-in, people using Office for Windows can now open their Word, Excel and Powerpoint documents stored in Drive and then save any changes back to Drive once they’re done
If you’re working on a document, spreadsheet or presentation that’s on your computer, you can also save that file to Google Drive, directly from the Office apps. This is especially useful for sharing files with teams, or for accessing your files across devices.
The Drive plug-in for Microsoft Office supports Word, Excel, and PowerPoint (2007, 2010, and 2013 versions), and Office 365 if you’ve downloaded and installed Microsoft Office on your computer as part of an Office 365 subscription.
