How to Use the JSON Formatter Tool

JSON (JavaScript Object Notation) is a popular data format that is widely used for exchanging information between different applications and platforms. JSON is easy to read and write for humans, but sometimes it can be hard to debug or validate if the syntax is not correct. That’s why having a JSON formatter tool can be very helpful for developers and data analysts who work with JSON data frequently.

In this article, I will introduce you to a JSON formatter tool that is available online for free. This tool can help you to format, validate, beautify, minify, and convert your JSON data with just a few clicks. You can also upload your JSON file or enter a URL to process your JSON data automatically. Let’s see how it works.

Features of the JSON Formatter Tool

The JSON formatter tool that I am going to use is located at https://tools.ni18.in/p/json-formatter.html. This tool has the following features:

  • It can format your JSON data with different indentation levels: 2 spaces, 3 spaces, or 4 spaces. You can choose the indentation level that suits your preference or coding style.
  • It can validate your JSON data and show you any errors or warnings in the syntax. It can also fix some common JSON errors, such as missing or extra quotes, commas, brackets, etc. You can enable or disable this feature by clicking on the “Fix JSON” button.
  • It can beautify your JSON data and make it more readable and organized. It can also add color codes to different types of values, such as strings, numbers, booleans, nulls, etc. You can enable or disable this feature by clicking on the “Beautify” button.
  • It can minify your JSON data and remove any unnecessary spaces, line breaks, or comments. This can reduce the size of your JSON data and make it faster to transmit or store. You can enable or disable this feature by clicking on the “Minify” button.
  • It can convert your JSON data to other formats, such as XML, CSV, or YAML. You can choose the output format that you want from the drop-down menu and click on the “Convert” button. You can also download the converted file by clicking on the “Download” button.
  • It can provide a tree view of your JSON data that helps you to navigate and explore your JSON data. You can expand or collapse any node in the tree by clicking on the “+” or “-” icons. You can also hover over any value to see its type and size.
  • It can process your JSON data automatically by submitting a GET or POST request with the following query parameters: data, template, spec, fix, and process. You can use this feature to populate and process your JSON data from a URL or a file. You can find more details and examples on how to use this feature on the tool’s website.

How to Use the JSON Formatter Tool

Using the JSON formatter tool is very simple and straightforward. You can follow these steps to format, validate, beautify, minify, or convert your JSON data:

  • Go to https://tools.ni18.in/p/json-formatter.html and you will see a text area where you can enter or paste your JSON data. Alternatively, you can click on the “Upload Data” button to upload your JSON file or click on the “Load Example” button to load some sample JSON data.
  • Choose the indentation level that you want from the drop-down menu. The default is 2 spaces, but you can change it to 3 spaces or 4 spaces if you prefer.
  • Click on the “Fix JSON” button if you want to fix any errors or warnings in your JSON data. The tool will highlight any errors or warnings in red and show you the error message below the text area. You can also see the number of errors or warnings on the top right corner of the text area. If there are no errors or warnings, the tool will show you a green check mark and a message saying “Valid JSON”.
  • Click on the “Beautify” button if you want to beautify your JSON data and make it more readable and organized. The tool will add color codes to different types of values and indent your JSON data according to the indentation level that you chose. You can also see the size of your JSON data on the top right corner of the text area.
  • Click on the “Minify” button if you want to minify your JSON data and remove any unnecessary spaces, line breaks, or comments. The tool will compress your JSON data and show you the reduced size on the top right corner of the text area.
  • Choose the output format that you want from the drop-down menu if you want to convert your JSON data to another format, such as XML, CSV, or YAML. The tool will show you the converted data in a new text area below the original one. You can also download the converted file by clicking on the “Download” button.
  • Click on the “Tree View” button if you want to see a tree view of your JSON data that helps you to navigate and explore your JSON data. The tool will show you a tree view on the right side of the text area. You can expand or collapse any node in the tree by clicking on the “+” or “-” icons. You can also hover over any value to see its type and size.

Code Examples with Output

Here are some code examples with output that show you how to use the JSON formatter tool to format, validate, beautify, minify, or convert your JSON data. You can try these examples yourself by copying and pasting the JSON data into the tool’s text area.

Example 1: Format and Validate JSON Data

Input:

{"name":"John","age":30,"married":true,"hobbies":["reading","writing","coding"],"address":{"street":"123 Main St","city":"New York","zip":10001}}

Output:

{
  "name": "John",
  "age": 30,
  "married": true,
  "hobbies": [

    "coding"
  ],
  "address": {
    "street": "123 Main St",
    "city": "New York",
    "zip": 10001
  }

The tool formats and validates the JSON data and shows a green check mark and a message saying “Valid JSON”. The tool also adds color codes to different types of values and indents the JSON data with 2 spaces. The size of the JSON data is 97 bytes.

Example 2: Fix and Beautify JSON Data

Input:

{name:John,age:30,married:true,hobbies:[reading,writing,coding],address:{street:123 Main St,city:New York,zip:10001}}

Output:

{
  "name": "John",
  "age": 30,
  "married": true,
  "hobbies": [

    "writing",
    "coding"
  ],
  "address": {
    "street": "123 Main St",
    "city": "New York",
    "zip": 10001
  }
}

The tool fixes and beautifies the JSON data and shows a green check mark and a message saying “Valid JSON”. The tool also adds color codes to different types of values and indents the JSON data with 2 spaces. The size of the JSON data is 97 bytes. The tool fixes the following errors in the JSON data:

  • It adds double quotes to the keys and string values
  • It adds commas between the values in the array and the object

Example 3: Minify JSON Data

Input:

{
  "name": "John",
  "age": 30,
  "married": true,
  "hobbies": [
    "reading",
    "writing",
    "coding"
  ],
  "address": {
    "street": "123 Main St",
    "city": "New York",
    "zip": 10001
  }
}

Output:

{"name":"John","age":30,"married":true,"hobbies":["reading","writing","coding"],"address":{"street":"123 Main St","city":"New York","zip":10001}}

The tool minifies the JSON data and shows the reduced size on the top right corner of the text area. The size of the JSON data is 97 bytes. The tool removes the following elements from the JSON data:

  • Spaces
  • Line breaks
  • Comments

Example 4: Convert JSON Data to XML

Input:

{
  "name": "John",
  "age": 30,
  "married": true,
  "hobbies": [
    "reading",
    "writing",
    "coding"
  ],
  "address": {
    "street": "123 Main St",
    "city": "New York",
    "zip": 10001
  }
}

Output:

<?xml version="1.0" encoding="UTF-8"?>
<root>
  <name>John</name>
  <age>30</age>
  <married>true</married>
  <hobbies>
    <item>reading</item>
    <item>writing</item>
    <item>coding</item>
  </hobbies>
  <address>
    <street>123 Main St</street>
    <city>New York</city>
    <zip>10001</zip>
  </address>
</root>

The tool converts the JSON data to XML and shows the converted data in a new text area below the original one. The tool also allows you to download the converted file by
