Alphabetically sorts the keys in selected JSON objects.
Please take care using this - I've tried to ensure it won't invalidate your JSON. But, as it has to parse > sort > stringify, there is a chance it'll lose something. It should be fine for plain JSON.

Install
Install via VSCode extensions install
Usage
