JSON Generator
The JSON Generator serializes data in a field to a JSON-encoded string. You can serialize data from List, Map, or List-Map fields.
When you configure the processor, you select the field that you want to convert and the field to write the JSON string data to.
If the target field exists, the JSON Generator overwrites the data in the field. If the data does not exist, the JSON Generator creates the field.
