Hi Akash,
Looks like you want to parse data from Json(https://jsonplaceholder.typicode.com/users) to apex. You can try online convertor https://json2apex.herokuapp.com/

To store data in custom object, retrieve that custom object record and use JSON.serialize() method. It will return a String containing JSON format of that record. Refer https://developer.salesforce.com/docs/atlas.en-us.apexcode.meta/apexcode/apex_class_System_Json.htm#apex_class_System_Json. 

Also see https://salesforce.stackexchange.com/questions/195686/json-to-store-on-custom-object/195689 for more details

Hi Swetha,

I am attaching the screenshot that what I had done yet and please guide me on what to do next

Wrapper Class:
public class UserWrapper {

    public class Geo {
		public String lat;
		public String lng;
	}

	public class Company {
		public String name;
		public String catchPhrase;
		public String bs;
	}

	public Integer id;
	public String name;
	public String username;
	public String email;
	public Address address;
	public String phone;
	public String website;
	public Company company;

	public class Address {
		public String street;
		public String suite;
		public String city;
		public String zipcode;
		public Geo geo;
	}

	
	public static List<UserWrapper> parse(String json) {
		return (List<UserWrapper>) System.JSON.deserialize(json, List<UserWrapper>.class);
	}
}

Main Class:
@RestResource(urlMapping='/ExternalUser/*')
global class DataImport {
    
    public static HttpResponse getMap(String Id){
        Http http = new Http();
        HttpRequest request = new HttpRequest();
        request.setEndpoint('https://jsonplaceholder.typicode.com/users');
        request.setMethod('GET');
        HttpResponse response = http.send(request);
        
        if(response.getStatusCode() == 200){
            System.debug(response.getBody());
            String body = response.getBody();
            System.debug('body: '+body);
            List<UserWrapper> result = UserWrapper.parse(response.getBody());
            System.debug('result : '+result);
            
        }
        return response;
    }
}

HI Akash,
Looks like the screenshot is missing.Are you seeing any error message? Can you run the below URI in the REST Explorer and see if it fetches the result you want?
/services/apexrest/ExternalUser/3
