Hi Customer,
I would like to answer your questions:
Q1: In order to us this and to access my documents that have made. Do I have to have Microsoft office?
A1: If you would like to access the Office documents which are on the local computer, you need install Microsoft Office.
If you need to access the Office documents which are on the Office 365 online server, you can use the Office Web Apps.
For details of Office Web Apps, you can review the article below:
