Sure, but it&#x27;s not very convenient.<p>I regularly MITM a connection between a mobile app and a HTTP server, when something isn&#x27;t going quite right. A look at the JSON they exchange exposes the problem in under a minute more often than not. If I want to test something out quickly, I simply modify the incoming &#x2F; outgoing JSON by hand. It&#x27;s rare to get the syntax wrong and involves no context switches. I can then go back to the code, find the relevant section and make the changes I need to make. I find this a very convenient way of debugging and I don&#x27;t think it would be as nice to do this with a binary format.
