JSON to Apex Convesion simpler now with http://json2apex.herokuapp.com

With the REST API being lot used when integrating apps developed on force.com paltform with the mobile applications or integrating force.com with external applications communicating using JSON it becomes vital to know few of open source tool we have to make our task simpler.

When we are in technology consulting world the time becomes crucial in any project we face .

There are couple of tools that i normally use whenever an integration is using REST API and the format of data communication is in the form of JSON .

In this blog i will describe two commonly used applications that makes life simpler when dealing with the JSON data.

1)http://jsonlint.com/

This application is very useful to format and Validate the JSON .All you need to do is input the JSON in the text box provided and click on Validate button to Validate the JSON .

JSON Lint is a web based validator and reformatter for JSON, a lightweight data-interchange format.

2)http://json2apex.herokuapp.com/

This was recently developed by salesforce evangelism (SuperFell and PattPatterson) and this is really helpful .The app is on the Heroku paltform and its really helpful of you want to construct an apex class from the JSON you have .

All you need is validated JSON (validate using jsonlint.com) is inputed and just a button click will give you the generated class and also the deserialiser method .

Lets see an example 

Say i have the JSON data as shown below 

{

    "id": "https://login.salesforce.com/id/00D90000000aRkLEAU/00590000000HI32AAG",

    "issued_at": "1355574766264",

    "instance_url": "https://ap1.salesforce.com",

    "signature": "LfOtSilg0GXb8NMO2YwcFvDTjRf8Ml0+jxI3XOozmuw=",

    "access_token": "00D90000000aRkL!ARIAQLLtJXpuyCteMrXEbkbEi6qZcgUhkeaK6_.Yqrxlz8JeOn"

}

Once i input this JSON into the app i get the following result

//
// Generated by JSON2Apex http://json2apex.herokuapp.com/
//

public class JSON2Apex {

 public String id;
 public String issued_at;
 public String instance_url;
 public String signature;
 public String access_token;

 
 public static JSON2Apex parse(String json) {
  return (JSON2Apex) System.JSON.deserialize(json, JSON2Apex.class);
 }
 
 static testMethod void testParse() {
  String json = '{'+
  ''+
  '    \"id\": \"https://login.salesforce.com/id/00D90000000aRkLEAU/00590000000HI32AAG\",'+
  ''+
  '    \"issued_at\": \"1355574766264\",'+
  ''+
  '    \"instance_url\": \"https://ap1.salesforce.com\",'+
  ''+
  '    \"signature\": \"LfOtSilg0GXb8NMO2YwcFvDTjRf8Ml0+jxI3XOozmuw=\",'+
  ''+
  '    \"access_token\": \"00D90000000aRkL!ARIAQLLtJXpuyCteMrXEbkbEi6qZcgUhkeaK6_.Yqrxlz8JeOn\"'+
  ''+
  '}';
  JSON2Apex obj = parse(json);
  System.assert(obj != null);
 }
}

This is really awesome .No more time consumed to draft the apex class Happy Coding!
