Dec 10th, 2014 It’s now possible to edit Office documents using Gmail
With Google Slides, not only will you be able to work with this type of file, but you'll also be able to share them easily with other users in your work group. Just like with all other Google tools, several users can work on the same file simultaneously. You can even work without an Internet connection and then apply the changes as soon as you go back online.
Google Slides users can add and reorganize slides, format text, insert images, manage numbered lists and spacing, and much more.
Google Slides is a very useful app for people who regularly work with presentations and need to have the best tool for doing so with them at all times.
