You can save your Office documents directly to Google Docs or directly open your online documents in Microsoft Office programs for reading and writing.

The plugin adds a new toolbar to your Microsoft Office suite of applications (Office 2003,2007 are supported). You can then log-in to either Google Docs or your Google Apps Account or both.

Once logged-in, you can browse through the list of your existing Google Docs documents from within Microsoft Office as if you were browsing files stored on the local file system. If you have too may documents in the root folder of Google Docs, you can use the built-in search function to limit that document list to a small set.

Now click the document name in Google Docs to open that file in the corresponding Microsoft Office application. A limitation is that you can’t download multiple documents from Google Docs in one go.

If you are editing an existing Google Docs document in Office or need to upload a new document from Microsoft Office to your Google Docs account, simply hit the "Save" button and the modified copy of the document will be saved to your online Google account.

Another advantage is that you can share Google Docs documents with multiple people right from Microsoft Office. Just specify the addresses of your contacts along with permissions (read- only or read-write).

It can’t get easier than this. And since Google Docs now supports the new Open XML format, you can also save Office 2007 format files (pptx, docs, xlsx) via the same plugin. Office Live Workspaces will also be integrated with Microsoft Office 2010 but until that is released, this plugin is a great choice.

 Q1.How do I upload all my Microsoft Office documents from the desktop on to Google Docs? Ans: List Uploader is a Windows utility that enables you to bulk upload files to Google Docs via drag-n- drop or through the right click menu.

Another option is GDocsBar – just drag your files in the Firefox sidebar and they’ll automatically get uploaded to Google Docs.
