The json package can be imported as encoding.json.*

It supports processing of JSON data and conversion among String, JsonValue and DataModel.

The JsonValue, JsonObject and JsonArray, as well as other classes defined within the package (See docs, API Reference/encoding module/encoding.json Package) can be used to process and/or create Json data.
