Looks like this question has been asked before buddy:

Retrive data from json file

Can anyone tell me how can I retrive only specific record from the below json using postman? [ { “endpoint” : “api/register/preprod”, “email”: “sydney@fife”, “password”: 5623 }, { “endpoint” : “api/register/preprod”, “email”: “abc@test”, “password”: 5234 }, { “endpoint” : “api/register/preprod”, “email”: “abc@test”, “password”: 5234 } ]
