How to use Word, Excel or PowerPoint for Android phones and tablets?
Word, Excel or PowerPoint apps are all available to download from Google Play. The free version will allow you to perform most functions on all three apps. You can create, edit, view and share files created on a PC. Files you create on your Android device can be uploaded to your PC and continue to edit using the desktop versions. You can save the files that you create on your Android device to Google Drive or to Microsoft OneDrive. The files can then be opened by any device (Windows, iOS, Android) and further edited and saved again.
If you create a Microsoft account you can purchase Office 365 to use on your PC and then easily share files between all your PCs and Android devices. The subscription to Office 365 is paid for using your Google Play Store account.
If you always save the files that you create using Microsoft Word, Excel or PowerPoint to the Microsoft OneDrive, then it is easy to save the file and then open again on another device to continue editing.
