Export Google Docs, Sheets and Slides format files to Office Open XML formats

posted Jan 18, 2013, 12:11 AM by Unknown user
In September, [Google] added the ability to export Google documents to the newer Microsoft Office formats that rely on open standards (.docx, .xlsx, .pptx). To continue adding new features and innovations to Google Drive and Docs, [Google will] be focusing [their] resources on exporting to these newer open formats rather than the older, proprietary Office formats (.doc, .xls, .ppt) that were used in Office 97-2003.

As [Google] announced in October, after January 31, 2013, users will not be able to export files to the older Office 97-2003 formats. For users who still use Office 97-2003, we recommend installing the free compatibility plugin from Microsoft, which will allow them to open the modern Office file types.
