JSON Beautifier Library for Java

Question

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

Answer 1

With Jackson 2.6.1

String beautify(String json) throws IOException {
    ObjectMapper mapper = new ObjectMapper();
    Object obj = mapper.readValue(json, Object.class);
    return mapper.writerWithDefaultPrettyPrinter().writeValueAsString(obj);
}

pom.xml:

    
        com.fasterxml.jackson.core
        jackson-core
        2.6.1
    

    
        com.fasterxml.jackson.core
        jackson-databind
        2.6.1
