Execute each child pipeline multiple times

Hi, 

I am calling the client_code as JSON Object  {"clients" : [{ "client_code": "OHSU"}, {"client_code":"scj"}]}
in pipeline parameter before mapping, but it converts into a string before passing to JSON Splitter Snap. 

This throws error. 

Hi SpiroTaleski 
I am receiving client details and their tokens in pipeline parameters via airflow. They are in JSON object now, as follows- 

{
    "clients": [
        {
            "client_code": "OHSU",
            "client_token": "xxxxxx"
        },
        {
            "client_code": "scj",
            "client_token": "xxxxxx"
        }
    ]
}

 But, JSON Splitter snap still throws error, as pipeline parameters defaults it to String. Is there a way to parse above JSON before sending to child pipelines?

One last question, Is it possible to process all client_codes in parallel? My current setup is passing the JSON details using router to several pipeline execute commands that call API child execution parallel. But I want to call parallel per client basis as well. (parallel execution of each document)
