How can I download a course roster?
SeyedSaeid Hosseinipoor, there isn't a button or specific feature for this in Canvas. You can technically download the gradebook, which would give you an excel file with the names of all the students, and then delete out the information you don't want - How do I download grades from the Gradebook?
Another thought would be to check the Student Information System at your Institution. They normally have a straightforward way of downloading/printing this off.
Otherwise, there was a feature idea for this - Printable course roster - that was archived, but has some interesting discussion AND there is also an add-on that you might find useful - Course Roster Enhancements
Hope this helps!
The printable PDF roster mentioned in the Course Roster Enhancements probably isn't functional right now, Canvas reorganized the toolbar that the button was put into a few months ago and so it doesn't appear any more. It probably wouldn't take long to fix, it's just not a priority for me right now.
I recommend using the export grades from the gradebook approach, although we ran into something this week where the names were showing up on the People page but they weren't in the gradebook. I'm guessing it was some combination of the names were manually added and the people couldn't accept because the course wasn't published, so the weren't technically active. When we added the people through the SIS, it marked them as active and put them into the gradebook and then we could download it.
