I am a librarian in a school of 900. Is there no other way to enroll students? I don't want to type (or paste) in emails.
Lisa, you haven't said if you are using a Free For Teachers account for Canvas, or if you have admin rights in your school's Canvas account. So I'll try to cover all of the possibilities.
The Add People step in this lesson includes example of acceptable email formatting. If you are copying and pasting from a spreadsheet where names are included with email addresses, please confirm the formatting aligns with the example text.
But I notice that you've said, "I don't want to type (or paste) in emails." Nevertheless, this is one of the three ways that you can add students to a Canvas course, and if you are using a Free For Teachers account, it is the only way. Again, if your school has an admin, the enrollments.csv upload is the fastest and cleanest way to populate a Canvas account not only with students but also with all users, courses, and more, as explained in the first guide to which I linked.
