learning sharing files/track changes using 1 computer.

[lezawang]

Hi
I have one computer. I want to learn how to Share/Track changes in excel. I want to see how 2 or more users can share a workbook and make changes and then track changes. Any idea how to simulate that? I am thinking to save a file in Google drive but how can I create 2 different dummy users, so they can open the sheet at same time etc. Any idea would be very much appreciated. Thank you.
