In JavaScript, parsing only analyzes and converts a program into an internal format that a runtime environment can run. For example, the JavaScript engine inside the browsers and the browser parse HTML into a DOM tree. 

A JavaScript value to a JSON string is by JSON.stringify() static method, optionally replacing the values if a replacer function is specified or optionally including only the specified properties if a replacer array is specified. String data will be easily converted to JSON using the stringify() function, and also it can be done using the eval() function, which accepts the JavaScript expression that we will learn about in this kit. A JSON object in text format to a Javascript object that can be used inside a program is JSON parsing is the process of converting. The unique approach to implementing this is by using the method JSON. 

  • json() method: it takes a response stream and then reads it to completion, and it returns a promise which resolves with the result of parsing the body text as JSON. 
  • JSON.parse(): it parses a JSON string, constructing the JavaScript value or object described by the string in JavaScript. An optional revived function can be provided to transform the resulting object before it is returned. 

Here is an example of how to parse and convert data type into JSON in JavaScript: 

Fig : Preview of the output that you will get on running this code from your IDE.



Follow the steps carefully to get the output easily.

  1. Install JavaScript ES6 code snippet and Code Runner from Extension on your IDE(We use Visual Studio Code).
  2. Copy the snippet using the 'copy' and create one new file filename.js(eg.test.js) then paste the code in that JavaScript file.
  3. Save the file and run the file using run button to generate the output.

I hope you found this useful.

I found this code snippet by searching for 'how to parse and convert data type into Json in javascript' in kandi. You can try any such use case!

Environment Tested

I tested this solution in the following versions. Be mindful of changes when working with other versions.

  1. The solution is created and tested in Visual Studio Code 1.74.1.
  2. JavaScript ES6 Code Snippet version v1.8.0.
  3. Code Runner version v0.11.8.

Using this solution, we are able to parse and convert datatype into json in javascript with simple steps. This process also facilities an easy way to use, hassle-free method to create a hands-on working version of code which would help us to parse and convert datatype into json in javascript.
