Google Cloud Connect was a free cloud computing plug-in for Windows Microsoft Office 2003, 2007 and 2010 that can automatically store and synchronize any Microsoft Word document, PowerPoint presentation, or Excel spreadsheet to Google Docs in Google Docs or Microsoft Office formats. The Google Doc copy is automatically updated each time the Microsoft Office document is saved. Microsoft Office documents can be edited offline and synchronized later when online. Google Cloud Sync maintains previous Microsoft Office document versions and allows multiple users to collaborate, working on the same document at the same time. Google Cloud Connect was discontinued on April 30, 2013, as according to Google, all of Cloud Connect's features are available through Google Drive.

Google Cloud Connect could automatically or manually synchronize changes made to a Microsoft Office 2003, 2007, or 2010 document with Google Docs. Documents can be secured for private access by one user, shared with specific people for collaboration, or made public to anyone. Previous document versions can be retrieved.
