Pretty-Print JSON in Java

Question

I'm using json-simple and I need to pretty-print JSON data (make it more human readable).

I haven't been able to find this functionality within that library. How is this commonly achieved?

Answer 1

GSON can do this in a nice way:

Gson gson = new GsonBuilder().setPrettyPrinting().create();
JsonParser jp = new JsonParser();
JsonElement je = jp.parse(uglyJSONString);
String prettyJsonString = gson.toJson(je);
