Technically, yes, you can do this...if you have certain software on your computer. It's not something that is built in to Canvas, however. Have you heard of a software program called Respondus 4.0 Exam Authoring Tool? It will allow you to create questions in a text or Word document (I've tried Excel, and it's much harder), and then upload that into Canvas. I've written an entire blog posting on the process which you can find here: Batch Uploading Quiz Questions with Respondus. This blog is located in the https://community.canvaslms.com/groups/admins group here in the Community, so if you are not a part of that group, you will want to click on the group link that I provided, and then click on the "Follow" button located at the top right corner of the screen. Also, in that same area is a button called "Actions". Go there, and then click on "Join group". I hope this info will be of help to you. If you have any questions about the content in the blog, please post your questions there, and I will do my best to answer. Thanks!
