XML & JSON for Web Development

JSON (JavaScript Object Notation) and XML (Extensible Markup Language) are both data interchange formats used for transmitting and storing data between applications. JSON is a lightweight data format that is easy for humans to read and write, and easy for machines to parse and generate. It is often used in web applications for exchanging data between the client and the server. XML, on the other hand, is a markup language that is used to structure and store data in a text format. It is used in a variety of applications and industries, including web development, document management, and data exchange between different systems. XML allows for more complex data structures and is often used for larger, more structured data sets.

What's JSON?

JSON (JavaScript Object Notation) is a lightweight data interchange format that is used to transmit and store data between different systems. It is a text-based format that is easy for humans to read and write, and easy for machines to parse and generate. In other words, it's a way to represent data in a structured way that can be easily understood by both humans and computers.
JSON is based on a subset of the JavaScript programming language and uses key-value pairs to represent and organize data. It can be used to exchange data between different programming languages and platforms, making it a very popular choice for web development, APIs, and other applications that require data exchange. One of the main advantages of JSON over other formats like XML is that it is much simpler and more compact. This makes it easier to work with for developers and reduces the amount of data that needs to be transmitted over networks, resulting in faster and more efficient data transfer.
In this JSON example, it shows a list of books:
  "books": [
      "title": "To Kill a Mockingbird",
      "author": "Harper Lee",
      "year": 1960
      "title": "1984",
      "author": "George Orwell",
      "year": 1949

When use JSON?

  1. Web Development: JSON is widely used in web development to exchange data between the client and the server. It's often used to retrieve data from a database or API and display it on a webpage.
  2. Data Exchange: JSON is often used as a data interchange format for exchanging information between different systems and platforms. This is used in applications like eCommerce, logistics, and healthcare.
  3. IoT: JSON is used in the Internet of Things (IoT) to transmit data between devices and the cloud. This is used in applications like smart homes, connected vehicles, and industrial automation.
  4. Mobile Development: JSON is also used in mobile development to transmit data between the mobile app and the server. This is commonly used in applications like mobile banking, eCommerce, and social media.
  5. Document Management: JSON can be used to store and manage structured data in a document format. This is used in applications like content management systems and document databases.

What's JSON5?

JSON5 is designed to be easier to read and write than traditional JSON, and it allows developers to include comments, trailing commas, single quotes, and other features that are not supported in standard JSON.
Comments: JSON5 allows developers to include comments in their code using the // or /* */ syntax, which is not allowed in standard JSON.
  // This is a comment
  "name": "John",
  "age": 30,
  "gender": "male"
Trailing Commas: JSON5 allows developers to include trailing commas at the end of object and array elements, which is not allowed in standard JSON.
  "hobbies": [


JSON5 is a well-defined and flexible specification that includes comments, trailing commas, and other features borrowed from ECMAScript 5.1. It's a strict subset of JavaScript and is supported by many popular programming languages and libraries, making it easy to integrate into different applications and platforms. In contrast, JSONC lacks a specification, is incompatible with other tools and tooling, and only offers the ability to add comments to JSON data. Overall, JSON5 is a better choice for developers who require a more powerful and flexible data representation format.

JSON5 Validator Online

JSON Validator Online is a web-based tool that verifies the integrity and syntax of JSON data according to the specifications of the JavaScript Object Notation (JSON) Data Interchange Format. This tool makes it easy to identify errors by highlighting the line numbers and providing detailed error descriptions. Additionally, there is a "Screwdriver" icon that acts as a JSON Fixer to repair the errors. With JSON Validator Online, there is no need to install any software, as the validation occurs directly in the browser with an internet connection. This makes it a convenient and accessible tool for anyone working with JSON data.

JSON5 Formatter

The JSON Formatter offers a range of useful features to help you work with JSON data. Firstly, it enables you to quickly validate JSON data and provides error messages to help identify any issues. It also has a "beautify" or "prettify" function that will format compact JSON and indent it correctly for easier reading. The tool supports live JSON formatting, meaning that as you type JSON data into the left editor, you will see a live formatted version in the right editor. In addition, you can also use the JSON Formatter as a JSON editor or JSON linting tool, providing increased functionality and versatility.

JSON5 Beautify/Prettify Online

JSON beautify or prettify online is a tool that takes compact JSON data as input and outputs a formatted and indented JSON that is easier to read and understand. This tool is particularly useful when dealing with large JSON files or when JSON data has been minified for efficiency purposes. When you use the JSON beautify or prettify tool, it takes the original JSON data and adds proper indentation and formatting, making it easier to navigate and read. The prettified JSON data is displayed in the right-hand side editor, and you have the option to copy it to your clipboard by clicking the "copy" button. This tool is helpful for developers who want to quickly format JSON data without having to manually add indentation or modify the data themselves. It can also help to identify errors or issues in the JSON data by making it easier to read and parse.

JSON5 Editor Online

If you need to edit your JSON data, the JSON editor provided by the tool is a helpful feature. The JSON editor supports auto indentation, meaning that as you add or remove elements from the JSON data, the editor will automatically add or remove the proper indentation for you. In addition, the editor highlights any errors or issues in the JSON data, making it easier for you to identify and correct them. The expand and collapse features of the JSON editor allow you to easily navigate through the JSON data, expanding or collapsing sections as needed. The JSON editor is a powerful tool for developers who need to modify or update JSON data. The rich features provided by the editor make it easy to work with JSON data and ensure that your changes are made accurately and efficiently.

JSON5 Viewer Online Tool

The JSON viewer online tool is a useful feature that allows you to inspect and search through JSON data. If you have JSON data that you need to examine or analyze, this tool provides an easy and efficient way to do so. With the JSON viewer, you can easily view the entire JSON data and analyze its structure. You can also search for specific fields or elements within the JSON data, making it easier to navigate and find the information you need. This tool is particularly useful for developers who need to work with large JSON files or who need to analyze complex JSON data structures. By providing a simple and intuitive interface for viewing and searching JSON data, the JSON viewer online tool saves developers time and effort when working with JSON data.
