How do I loop the JSON Request with different customer object data in Postman?

How do I loop the JSON Request with different customer object data in POSTMAN? I'm looking to load a web application with test data.

{
  "customer": {
   "external_id": "EXT1221",
    "name": "Elon Musk",
    "address": "1405 North Ave, Chicago",
        "address_second_line": "Apt 2",
    "phone": "522-525-5555",
    "email": "elon@company.com",
    "zipcode": "60612",
    "lat": "40.7833404",
    "lng" : "-73.9527781",
    "merchant_id" : 11271,
    "confirmation_code" : "5320",
    "allow_login" : true,
    "allow_sending_email" : true,
    "allow_sending_sms" : true,
    "language": "en"
    }
}
