Use the JSON.parse() method to convert the JSON string to an object in JavaScript. If this method is used on JSON derived from an array, the method will return a JavaScript array, instead of a JavaScript object.
JSON.parse(jsonString);Note: The JSON string must be well-formed for the JSON.parse() method to work correctly. If the JSON string contains any syntax errors, the JSON.parse() method will throw an error.
If you’re using jQuery just use:
jQuery.parseJSON( jsonString );JSON string to object example
Simple example code.
<!DOCTYPE html>
<html>
<body>
<script >
const jsonString = '{"name":"John","age":30,"city":"New York"}';
console.log(typeof(jsonString))
const obj = JSON.parse(jsonString);
console.log(obj);
console.log(typeof(obj))
</script>
</body>
</html>
Output:
