Can you clarify what you mean by a grade sheet? If you're just trying to get columns in the gradebook, you'd need to import the assignments from the pervious course shell to the new one: How do I copy content from another Canvas course u... - Instructure Community . If you're trying to transfer actual grades, that's going to be much harder, as Canvas isn't really designed to do that. If the new course had the exact same students enrolled as the old course, you could theoretically import the assignments as I indicated below, then do a gradebook export in the old course and import it into the new course. This would only transfer grades and not any comments, submissions, etc though, and I'd really recommend against going this direction.
I hope this helps a bit, but let us know more details and we can try to offer some additional help if needed.
