We can use JSON.parse() or eval() function to create json object from string in javascript.
Using JSON.parse() function:
Syntax: var obj = JSON.parse(textString);
Example:
<!DOCTYPE html>
<html>
<body>
<h2>Create json object from string.</h2>
<p id="testDemo"></p>
<script>
var textString = '{"students":[' +
'{"firstName":"Sandy","lastName":"Sethi" },' +
'{"firstName":"Roxy","lastName":"Malik" },' +
'{"firstName":"Sunil","lastName":"Antil" }]}';
var obj = JSON.parse(textString);
document.getElementById("testDemo").innerHTML =
obj.students[0].firstName + " " + obj.students[0].lastName;
</script>
</body>
</html>

Using eval() function:
Syntax: var obj = eval (“(” + textString + “)”);
Example:
<!DOCTYPE html>
<html>
<body>
<h2>Create json object from string.</h2>
<p id="testDemo"></p>
<script>
var textString = '{"students":[' +
'{"firstName":"Sandy","lastName":"Sethi" },' +
'{"firstName":"Roxy","lastName":"Malik" },' +
'{"firstName":"Sunil","lastName":"Antil" }]}';
obj = eval ("(" + textString + ")");
document.getElementById("testDemo").innerHTML =
obj.students[1].firstName + " " + obj.students[1].lastName;
</script>
</body>
</html>
