There is no direct functionality within Canvas that will batch export your course Discussion posts into a Word or PDF file, but you can use one of the options below as a work around to view and save a copy of your replies. If your recent messages doesn't list all of your replies, you can follow the second method to access them.
User's recent messages
- Enter a discussion where you've posted and scroll to that post.
- Click on your name within that discussion.
- You'll then be taken to a page that displays your recent messages.
Individual discussions
- Enter your course, then navigate to the corresponding Discussion that has the replies you want to save.
- Enter your name in the search bar.
- Select/Highlight all of the responses that appear in the search results.
- Copy (CTRL+C on Windows; CMD+C on Mac) the text.
- Open a Word/Google/text document, then paste (CTRL+V on Windows; CMD+V on Mac).
- Save that file to your machine and repeat for as many discussions as you'd like to save.
