Microsoft recently released a version of their Office Suite for Android. Yet it was only available as a preview version for a select group of people who signed up for it. Today it has become available to the general public as a Preview version.
If you'd like to use the Android version of Office, all it requires is an ARM-based Android tablet with a display size of 7 to 10.1 inches. It must run Android 4.4 KitKat or higher.
All 3 apps are available separately just like Office for the iPad. You can head over to the Google Play store to download Word, Excel, and PowerPoint.
