converting pure string to JSON

I have a string like below

 "{stockName: NSE:APOLLOTYRE, stockSignal: Buy, triggerPrice: 204.25, triggerDate: 44900}"

Now how can I convert this to json as below:

    {
    stockName: APOLLOTYRE, 
    stockSignal: Buy, 
    triggerPrice: 204.25, 
    triggerDate: 44900
}

Please note that "NSE:" should be deleted from resulting JSON I tried below code but obviously it not working.

 var data_array = input.body.split(',');
        var json = JSON.stringify(data_array);
        console.log(json);

You can use String.replace to add quotes to the properties in your pseudo-JSON to convert it to proper JSON, then use JSON.parse:

var input = "{stockName: NSE:APOLLOTYRE, stockSignal: Buy, triggerPrice: 204.25, triggerDate: 44900}";

var withQuotes = input.replace(/(\b[a-z]+:)?(\b[a-z]+\b)/gi, '"$2"');

var parsed = JSON.parse(withQuotes);

console.log(parsed);

For transorm your string into JSON object you have to make this:

var s = "{stockName: APOLLOTYRE, stockSignal: Buy, triggerPrice: 204.25, triggerDate: 44900}"

like this:

var s = "{\"stockName\": \"APOLLOTYRE\", \"stockSignal\": \"Buy\", \"triggerPrice\": 204.25, \"triggerDate\": 44900}"

and after you can parse it from json to javaScript object with

JSON.parse(s);

You can try something like this:

var s = "{stockName: APOLLOTYRE, stockSignal: Buy, triggerPrice: 204.25, triggerDate: 44900}";

s = s.replace(/{/g, '{\"');

s = s.replace(/}/g, '\"}');

s = s.replace(":", '\":\"');

s = s.replace(/, /g, '\",\"');

JSON.parse(s);
