i'm not sure what you mean by styled. json usually looks like this {user:{name:'fred',age:65}}. what kind of styling did you want to apply to that? i'm guessing, but it sounds like you're looking for html elements to be returned?
typically after the request happens you can just use jquery's .html() method to insert your json into the element:
$('.element').html(json-data-returned-from-server) where .element is the class name used by the html tag you're trying to insert your json.
json is just a string so it's will be hard to add styling other than a font size, and font color.
