JSON Beautifier Library for Java

I want to format a string containing JSON data using Java. Does anybody know an open source library for that.

Solution

  • Assuming you're starting out with an existing JSON string, then Jackson can do this for you:

    ObjectMapper objectMapper = new ObjectMapper();
objectMapper.configure(SerializationConfig.Feature.INDENT_OUTPUT, true);

String originalJson = ...
JsonNode tree = objectMapper .readTree(originalJson);
String formattedJson = objectMapper.writeValueAsString(tree);
