Using org.json library in Java to beautify printing JSON data?

JSON is a lightweight, text-based and language independent The protocolstrong>data exchange format. A.JSONObject can parse the text in a string to generate an object similar to Map. This object provides methods for manipulating its contents and generating JSON-compliant serialization of the object. org.json Files in the package implement JSON encoders/decoders in Java. It also includes functionality to convert between JSON, XML, HTTP headers, cookies, and CDL.

We can pretty print# using the toString(int indentFactor) method of the org.json.JSONObject class ## JSON, where indentFactor is the number of spaces to add to each indent level.

Syntax

public java.lang.String toString(int indentFactor) throws JSONException

Example

import org.json.*;
public class JSONPrettyPrintTest {
   public static void main(String args[]) throws JSONException {
      String json = "{" +
                    "Name : Jai," +
                    "Age : 25, " +
                    "Salary: 25000.00 " +
                    "}";
      JSONObject jsonObj = new JSONObject(json);
      System.out.println("Pretty Print of JSON:");
      System.out.println(jsonObj.toString(4)); // pretty print json
   }
}

Output

Pretty Print of JSON:
{
   "Salary": 25000,
   "Age": 25,
   "Name": "Jai"
}
