[![Maven Central](https://badgen.net/maven/v/maven-central/com.cedarsoftware/json-io)](https://central.sonatype.com/search?q=json-io&namespace=com.cedarsoftware)

[![Javadoc](https://javadoc.io/badge/com.cedarsoftware/json-io.svg)](http://www.javadoc.io/doc/com.cedarsoftware/json-io)

Useful tool for Java serialization to and from JSON format.

Available on [Maven Central](https://central.sonatype.com/search?q=json-io&namespace=com.cedarsoftware).

This library has no dependencies on other libraries for runtime other than our own `java-util.`

The `json-io.jar`file is `220K` and `java-util` is `336K.` Compatible with JDK1.8 through JDK 23.

## Compatibility

### JPMS (Java Platform Module System)

This library is fully compatible with JPMS, commonly known as Java Modules. It includes a `module-info.class` file that

specifies module dependencies and exports.

### OSGi

This library also supports OSGi environments. It comes with pre-configured OSGi metadata in the `MANIFEST.MF` file, ensuring easy integration into any OSGi-based application.

Both of these features ensure that our library can be seamlessly integrated into modular Java applications, providing robust dependency management and encapsulation.
