Data Format
The format of the incoming input and output data.
Supported data formats are JSON,and Delimited and None. Whatever format is presented to the input terminal will be produced on the output terminal as well. For example, if a JSON array is sent to the input terminal, the output terminal will also produce a JSON array. If the Data Format is None, a new property “Key” is enabled to specify the name of the key to be retrieved and send to the output.
