how to use JSON output

Hello,

I have one scenarion where I am getting output in JSON format . 
JSON - {"SystemModstamp":{"oldValue":"2021-06-10T08:32:25.000Z","value":"2021-06-10T09:03:24.000Z"},"Status":{"oldValue":"New","value":"Accept"}}

I want to use this output in IF condition in my JS of lightning component. Like if Status Value is' Accept' then do my logic.
P.S.  SystemModstamp, Status both are fields of Lead.

Please help me on this. Thanks in advance

Hi Shubham,

You could use Apex code like below to get the parsed values from json and then use it accordingly by storing in some variable, Here is sample code for your understanding: 
List<Object> fieldList = (List<Object>)JSON.deserializeUntyped('[{"oldValue":"2021-06-10T08:32:25.000Z","value":"2021-06-10T09:03:24.000Z"},{"oldValue":"New","value":"Accept"}]');
for(Object fld : fieldList){    
    Map<String,Object> data = (Map<String,Object>)fld;
    
    //Magic!
    system.debug(data.get('value'));
}
Also, we have JSON to Apex application(https://json2apex.herokuapp.com/) where the response can be converted to get the relevant apex and then you can process the response according to the standard documentation as mentioned in below links:
https://developer.salesforce.com/docs/atlas.en-us.apexcode.meta/apexcode/apex_json_jsonparser.htm

Hi Shubham,

I don't know you are using the LWC or Aura.

But you can try like below :

You no need to declare JSON string for testing purpose i have created 

var jsonstr = '{"SystemModstamp":{"oldValue":"2021-06-10T08:32:25.000Z","value":"2021-06-10T09:03:24.000Z"},"Status":{"oldValue":"New","value":"Accept"}}';

var jStr = JSON.parse(jsonstr);

console.log('jsonstr --> ' + JSON.parse(jsonstr));

var Acceptbool = false;

for(var key in jStr){
   if(key == 'Status'){
     console.log('***' + jStr[key].value);
     if(jStr[key].value == 'Accept'){
       Acceptbool = true;
     }
   }
}

console.log('Acceptbool --> ' + Acceptbool );

if(Acceptbool){
   //  do your logic
}

Thanks,
Maharajan.C

Hi Shubham,
Greetings!

There are two ways to handle this JSON.
First, create a wrapper class with these variables to directly deserialize JSON using your wrapper class.
Second, Please use deserializeUntyped to break this JSON into Map where the key is String and Value is Object.

If you find your Solution then mark this as the best answer. 

Thank you!
