JSON in Java [package org.json]

Click here if you just want the latest release jar file.

Overview

JSON is a light-weight language-independent data interchange format.

The JSON-Java package is a reference implementation that demonstrates how to parse JSON documents into Java objects and how to generate new JSON documents from the Java classes.

Project goals include:

Reliable and consistent results
Adherence to the JSON specification
Easy to build, use, and include in other projects
No external dependencies
Fast execution and low memory footprint
Maintain backward compatibility
Designed and tested to use on Java versions 1.6 - 21

The files in this package implement JSON encoders and decoders. The package can also convert between JSON and XML, HTTP headers, Cookies, and CDL.
