Question

I want to convert this:

{
  "firstName": "John",
  "lastName": "Smith",
  "fullName": "John Smith",
  "age": "32",
  "emailAddress": "smith1234@hotmail.com",
  "dob": "1988-12-06",
  "billingAddress__streetAddress": "21 2nd Street",
  "billingAddress__city": "New York",
  "billingAddress__state": "NY",
  "billingAddress__postalCode": "10021",
  "shippingAdress__streetAddress": "21 2nd Street",
  "shippingAdress__city": "New York",
  "shippingAdress__state": "NY",
  "shippingAdress__postalCode": "10021",
  "phoneNumber": [
    {
      "type": "home",
      "number": "212 555-1234"
    },
    {
      "type": "fax",
      "number": "646 555-4567"
    },
    {
      "type": "mobile",
      "number": "212 555-1299"
    }
  ]
}

To this:

{
  "firstName": "John",
  "lastName": "Smith",
  "fullName": "John Smith",
  "age": "32",
  "emailAddress": "smith1234@hotmail.com",
  "dob": "1988-12-06",
  "billingAddress__streetAddress": "21 2nd Street",
  "billingAddress__city": "New York",
  "billingAddress__state": "NY",
  "billingAddress__postalCode": "10021",
  "shippingAdress__streetAddress": "21 2nd Street",
  "shippingAdress__city": "New York",
  "shippingAdress__state": "NY",
  "shippingAdress__postalCode": "10021",
  "phoneNumber__home": "212 555-1234",
  "phoneNumber__fax": "646 555-4567",
