@JonBurt and @DonaldRumsey ...
You do not need to export your Gradebook to get just a roster of your students. I'm not sure if either of you have used New Analytics at all within your Canvas course(s), but you can get a downloadable student roster from there, too. It's a *.csv file that you should be able to open in Excel or even Google Sheets. Check out the instructions in this Guide:
How do I view and download reports in New Analytics?
As you can see from the Guide, there is a report you can run for "Class Roster". There are a few other reports there, too, which you might be interested in running at some time.
I hope this will be of some help to both of you.
