Viewing files that are saved on my Galaxy S4 on my chromebook or windows laptop

AC Question

Ok, so I broke my phone screen today and I want to get my contacts off the phone, but the screen is completely black. I have a chromebook and a Windows laptop. I tried connecting the phone to both laptops via USB drive, but to no avail. What are my options? I know all my contacts are backed up in the cloud, but is there anyway to view the things saved in my phones cloud on my chromebook? And FYI, I have no clue how to work "the cloud" it's just something extremely mysterious to me lol. Thanks for any help.
