For this, you can use replace() along with parse(). Following is the code −
Example
var studentDetails = `"{""name"": ""John"",""subjectName"": ""Introduction To JavaScript""}"`; console.log("The actual object="); console.log(studentDetails); var removeFirstAndLast = studentDetails.substring(1,studentDetails.length-1) var removeDoubleQuotes = removeFirstAndLast.replace(/""/gi, `"`) console.log(removeDoubleQuotes) var output = JSON.parse(removeDoubleQuotes); console.log(output);
To run the above program, you need to use the following command −
node fileName.js.
Here, my file name is demo103.js.
Output
This will produce the following output −
PS C:\Users\Amit\JavaScript-code> node demo103.js The actual object= "{""name"": ""John"",""subjectName"": ""Introduction To JavaScript""}" {"name": "John","subjectName": "Introduction To JavaScript"} { name: 'John', subjectName: 'Introduction To JavaScript' }
