Pretty-Print JSON in Java Using GSON

Manipulating JSON data requires tools that facilitate its readability and comprehension. For those utilizing the json-simple library and seeking a means to prettify their JSON data, GSON, developed by Google, presents a reliable solution.

Pretty-Printing JSON with GSON

To achieve pretty-printed JSON using GSON, follow these steps:

1. Import the GSON library into your project:

   import com.google.gson.*;

2. Specify the pretty printing setting:

   Gson gson = new GsonBuilder().setPrettyPrinting().create();

3. Parse the JSON string to a JSON element:

   JsonElement je = JsonParser.parseString(uglyJsonString);

4. Convert the JSON element to a pretty-printed string:

   String prettyJsonString = gson.toJson(je);

Example Code

The following code snippet demonstrates the usage of GSON for pretty-printing JSON:

Gson gson = new GsonBuilder().setPrettyPrinting().create();
JsonElement je = JsonParser.parseString(uglyJsonString);
String prettyJsonString = gson.toJson(je);
System.out.println(prettyJsonString);

Dependency

Integrate the following dependency in your Gradle configuration:

implementation 'com.google.code.gson:gson:2.8.7'

Using GSON provides an elegant solution for prettifying JSON data in Java, enhancing its readability and usability for debugging or presentation purposes.
