The easiest way to download your roster as a CSV or Excel file is to enable the “gradebook” tool and get the roster from there.
To turn on the gradebook, visit “site settings” and then “edit tools”. Enable the gradebook option and finish the tool activation.
Once the gradebook is enabled, visit the tool and then click on the “Import Grades” tab. There you’ll notice links to CSV and Excel templates, which provides a formatted roster list.
Accessing the roster this way offers the added advantage of providing a pre-formmated spreadsheet that will work with the gradebook’s “upload” features.
