Microsoft had launched the tablet version of the Office Android apps in January this year. They are very similar to the Office Android apps for smartphones and will let you create, open, and edit office documents.
The apps integrate with OneDrive, OneDrive for Business, SharePoint, Dropbox, Google Drive and Box so you can easily open or save your files while on the go. More importantly you can access the files and make changes from any other device or platform because the files are stored in the cloud.
The new Office app previews for Android phones require Android KitKat 4.4.x or higher and devices with 1 GB of RAM or more. Microsoft is aiming to release Office for Windows 10 Mobile by the end of the year.
