Using a map in a Data Integration Job

Create a Job to convert a JSON file into a CSV.

About this task

In this example, you have a JSON file containing customer information, including arrays of different types of phone numbers. The goal is to convert it into a simple CSV file with a column for each piece of information. You can use the following JSON sample as input:
{
   "customers":[
      {
         "firstName":"John",
         "lastName":"Smith",
         "age":25,
         "address":{
            "streetAddress":"21 2nd Street",
            "city":"New York",
            "state":"NY",
            "postalCode":"10021"
         },
         "phoneNumber":[
            {
               "type":"home",
               "number":"202-555-0109"
            },
            {
               "type":"mobile",
               "number":"202-555-0181"
            }
         ]
      },
      {
         "firstName":"Jane",
         "lastName":"Doe",
         "age":31,
         "address":{
            "streetAddress":"19 4th Street",
            "city":"New York",
            "state":"NY",
            "postalCode":"10021"
         },
         "phoneNumber":[
            {
               "type":"home",
               "number":"202-555-0178"
            },
            {
               "type":"mobile",
               "number":"202-555-0123"
            },
            {
               "type":"work",
               "number":"202-555-0163"
            }
         ]
      }
   ]
}
