How do I bulk download assignment submissions in Canvas?
Bulk downloading assignments will take all the submissions and create a ZIP file that you can download and grade on your computer. If a student has resubmitted an assignment, only the most recent submission will be included in the ZIP file.
Bulk downloads can be used for the following submission types: file uploads, text entries (displayed as HTML files), website URLs (displayed as HTML files), and Google Docs submissions.
You can also download assignments in SpeedGrader.
Note: If you want to bulk upload assignment submissions, you cannot change the names of the submission files. Otherwise Canvas will not be able to recognize the files that should be replaced.
