The sample employee json object :

{
     "status": "success",
     "data": {
         "id": "2",
         "employee_name": "Garrett Winters",

         "employee_age": "63",
         "profile_image": ""
     }
 }

To work with JSON in Python, we need to import the python JSON module.

How To Write JSON File in Python

We will write JSON file in Python using json.dump() method. Let’s create json_example.py file and write the below code into this file.

import sys
import requests
from colorama import Fore, init, Back, Style
import json

url = "https://dummy.restapiexample.com"
headers = {'Content-Type': 'application/json'}

def employees():
    try:
        res_data = []
        resp = requests.get(url = url, headers = headers)
        if resp.status_code == 200:
            service_data = resp.json()
            for service in service_data["data"]:
                if service["employee_name"] != None :
                    tmp = {}
                    tmp['id']=service["id"]
                    tmp['employee_name']=service["employee_name"]
                    res_data.append(tmp)
            return res_data
        else :
            return res_data
    except Exception as e:
        print (Fore.RED + "ERROR ! To get employee data.")
        print(e)
	return res_data

init(convert=True)
print("\n")
try:
    emps = employees()
    print("===========================================================")
    if len(emps) >= 0:
        with open('employee.json', 'w') as outfile:
            json.dump(emps, outfile)
			print(emps)

except Exception as e:
    print(e)
    print (Fore.RED + "Error : The emp api")
print(Fore.GREEN + "###################### Successfully! created json file. ##############################")

In the above code, Created employees() method to get data from the rest API using the request package. This method returns the array of employee data.

We have opened a file named employee.txt in writing mode using 'w'. If the file doesn’t already exist, it will be created. Then, json.dump() transforms emps to a JSON string which will be saved in the employee.txt file.

When you run the program, the employee.txt file will be created. The file has all employees data.
