Online Free JSON Formatting and Comparing using HTML



JSON (JavaScript Object Notation) is a common data transfer format that is known for its simplicity and compatibility with a wide range of computer languages. When working with JSON, formatting and comparing JSON objects can help to improve readability and data analysis. We'll look at how to implement it with HTML and JavaScript in this lesson.

Implementation

Setting Up the Environment

Let's start by making a simple HTML website that allows us to enter JSON data and conduct formatting and comparison operations. We'll build the feature with HTML, CSS, and JavaScript. The HTML code structure is as follows:

<!DOCTYPE html>
<html>
<head>
  <title>JSON Formatter and Comparator</title>
  <!-- CSS Styles -->
</head>
<body>
  <h1>JSON Formatter and Comparator</h1>

  <!-- JSON Input Fields -->

  <!-- Formatting and Comparison Buttons -->

  <!-- Result Display Section -->

  <!-- JavaScript Code -->
</body>
</html>


Input Fields in JSON

We'll construct two text fields within the body> section for inserting JSON items. Users can submit JSON data in these fields, which we will format and compare afterwards. To construct the input fields, add the following code:

<h2>JSON Input 1:</h2>
<textarea id="jsonInput1" placeholder="Enter JSON object 1"></textarea>

<h2>JSON Input 2:</h2>
<textarea id="jsonInput2" placeholder="Enter JSON object 2"></textarea>


Buttons for Formatting and Comparison

The buttons that initiate the formatting and comparison procedures will be added next. Users can use these buttons to prepare and compare JSON objects. To make the buttons, use the following code:


<button id="formatBtn" onclick="formatJSON()">Format JSON</button>
<button id="compareBtn" onclick="compareJSON()">Compare JSON</button>


Section for Result Display

To show the outcomes of the actions, we'll add a div> element with an ID for subsequent identification. This part will display the results of the JSON comparison. To build the result display section, enter the following code:

<div id="result"></div>

JavaScript Code

Finally, we'll write the JavaScript methods that handle formatting and comparison. Within the script> element, paste the following JavaScript code:

<script>
function formatJSON() {
  // JSON formatting logic
}

function compareJSON() {
  // JSON comparison logic
}
</script>


The JSON input will be gathered from the text sections, and processed using the JSON.parse() method, and then formatted with indentation using the JSON.stringify() function. The text fields will get the returned formatted JSON objects.

The JSON input will be taken from the text fields, processed using JSON.parse(), and compared using JSON.stringify() in the compareJSON() function. The result will be displayed in the section devoted to results.


Wrapping UP

That's all! Thanks to the HTML structure and JavaScript functionalities, you now have a simple online tool for formatting and comparing JSON objects. You may improve this tool further by adding error handling, more customization choices, or integrating it into a bigger online application.

JSON formatting and comparison are useful strategies for properly working with JSON data. You may easily prepare JSON for greater readability and compare JSON items to detect differences or similarities by using this simple HTML-based tool.

Feel free to play with the code and modify it to meet your personal requirements. Have fun coding!
