'How to change response body with Charles?

I am using Charles (http://www.charlesproxy.com) to debug my HTTP requests and now I run into an issue where I am receiving json response which I need to edit to see how my app behaves.

I was looking at Rewrite option but can't really figure out how to change it. Ideal would be to load whole response from disk.

Any ideas how to accomplish this? Thank you.

Enable breakpoints, then change response. You should press continue/send request to send it before tweak response.
