@MarciaPhillips ...
If you are an instructor, there are a few places that you can view all your students. One place is the "People" page of your course:
If you want to see a listing of your students in your "Grades" page, just click on the "Grades" course navigation menu item on the left-hand side of your screen.
You can also export a listing of your students and their grades as a *.csv file ... if you prefer to do that:
Finally, there is another way to export your course roster ... via "New Analytics":
On this screen, you'll find that one of the options is "Course Roster" where you can click on the "Run Report" button.
I hope this will be of some help to you. Sing out if you have any other questions...thanks!
