Starting immediately, users can click the new “edit” option by hovering the attachment, and Gmail will convert the file to Google’s format, uploading the file to Google Drive, which users can then continue editing and sharing with other people.

If you don’t want Google converting the file type, the company recommends you use the Office Editing Chrome extension. The extension isn’t new, it’s been around for a while, and it allows you to edit Microsoft Office documents while preserving its original format using Chrome. Also Google Docs now supports 15 new Office file types including: pps and ppsx, macro-enabled files, and template files. Though, this is a convenient way to edit files on your inbox if you don’t have Office installed. But remember that you can always download the document received on Gmail and edit it using Office Online. Source Google+ All content on this site is provided with no warranties, express or implied.
