I don't think you can get Microsoft Office for an Android tablet. I use an app called Smart Office 2 on my Samsung smart phone. It doesn't cost much and is available from Google Play Store. It reads and writes .doc, .docx, ppt, pptx, xls and xlsx files. I've not used it much especially for creating files, writing documents etc on a smart phone is not a good idea IMO. I have used it to read those file types and it works okay.
