JSON is used to store information in an organized and easy-to-access manner. JSON stands for JavaScript Object Notation. It offers a human-readable collection of data that can be accessed logically. ## What is XML? **[XML](https://www.guru99.com/xml-tutorials.html)** is an extensible markup language that is designed to store data. It is popularly used for transferring data. It is case-sensitive. XML allows you to define markup elements and generate customized markup language. An element is a basic unit in the XML language. The extension of XML file is .xml. ## History of JSON Here are important landmarks that form the history of JSON: - Douglas Crockford specified the JSON format in the early 2000s. - The official website was launched in 2002. - In December 2005, Yahoo! starts offering some of its web services in JSON. - JSON became an ECMA international standard in 2013. - The most updated JSON format standard was published in 2017. ## History of XML Here, are the important landmark from the history of XML: - XML was also derived from SGML. - Version 1.0 of XML was released in February 1998. - Jan 2001:IETF Proposed Standard: XML Media Types - XML is the Extensible Markup Language. - 1970: Charles Goldfarb, Ed Mosher, and Ray Lorie invented GML - The development of XML started in the year 1996 at Sun Microsystem ## Features of JSON - **Easy to use** – JSON API offers high-level facade, which helps you to simplify commonly used use-cases. - **Performance** – JSON is quite fast as it consumes very less memory space, which is especially suitable for large object graphs or systems. - **Free tool** – JSON library is open source and free to use. - **Doesn’t require to create mapping** – Jackson API provides default mapping for many objects to be serialized. - **Clean JSON** – Creates clean, and compatible JSON result that is easy to read. - **Dependency** – JSON library does not require any other library for processing. ## Features of XML - XML tags are not predefined. You need to define your customized tags. - XML was designed to carry data, not allows you to display that data. - Mark-up code of XML is easy to understand for a human. - Well, the structured format is easy to read and write from programs. - XML is an extensible markup language like HTML. **Don't Miss:** - [Web Service (WS) Security with SOAP Example](https://www.guru99.com/security-web-services.html) - [Web Services Tutorial for Beginners](https://www.guru99.com/web-services-tutorial.html) - [API vs Web Service – Difference Between Them](https://www.guru99.com/api-vs-web-service-difference.html) - [SOA vs Microservices – Difference Between Them](https://www.guru99.com/microservices-vs-soa.html) ## Difference between JSON and XML [![Difference Between JSON and XML]()](https://www.guru99.com/images/1/090719_0543_JSONvsXMLWh1.png) *Difference between JSON and XML* Here is the prime difference between JSON vs XML: | JSON | XML | | --- | --- | | JSON object has a type | XML data is typeless | | JSON types: string, number, array, Boolean | All XML data should be string | | Data is readily accessible as JSON objects | XML data needs to be parsed. | | JSON is supported by most browsers. | Cross-browser XML parsing can be tricky | | JSON has no display capabilities. | XML offers the capability to display data because it is a markup language. | | JSON supports only text and number data type. | XML support various data types such as number, text, images, charts, graphs, etc. It also provides options for transferring the structure or format of the data with actual data. | | Retrieving value is easy | Retrieving value is difficult | | Supported by many Ajax toolkit | Not fully supported by Ajax toolkit | | A fully automated way of deserializing/serializing [JavaScript](https://www.guru99.com/introduction-to-javascript.html). | Developers have to write JavaScript code to serialize/de-serialize from XML | | Native support for object. | The object has to be express by conventions – mostly missed use of attributes and elements. | | It supports only UTF-8 encoding. | It supports various encoding. | | It doesn’t support comments. | It supports comments. | | JSON files are easy to read as compared to XML. | XML documents are relatively more difficult to read and interpret. | | It does not provide any support for namespaces. | It supports namespaces. | | It is less secured. | It is more secure than JSON. | ## JSON Code vs XML Code Let’s see a sample JSON Code ``` { "student": [ { "id":"01", "name": "Tom", "lastname": "Price" }, { "id":"02", "name": "Nick", "lastname": "Thameson" } ] } ``` Let’s study the same code in XML ``` 01 Tom Price 02 Nick Thameson ``` ## Advantages of using JSON Here are the important benefits/ pros of using JSON: - Provide support for all browsers - Easy to read and write - Straightforward syntax - You can natively parse in JavaScript using eval() function - Easy to create and manipulate - Supported by all major JavaScript frameworks - Supported by most backend technologies - JSON is recognized natively by JavaScript - It allows you to transmit and serialize structured data using a network connection. - You can use it with modern programming languages. - JSON is text which can be converted to any object of JavaScript into JSON and send this JSON to the server. ## Advantages of using XML Here are significant benefits/cons of using XML: - Makes documents transportable across systems and applications. With the help of XML, you can exchange data quickly between different platforms. - XML separates the data from HTML - XML simplifies platform change process - Allows creating user-defined tags. ## Disadvantages of using JSON Here are cons/ drawback of using JSON: - No namespace support, hence poor extensibility - Limited [development tools](https://www.guru99.com/software-development-tools.html) support - It offers support for formal grammar definition ## Disadvantages of using XML Here, are cons/ drawbacks of using XML: - XML requires a processing application - The XML syntax is very similar to other alternatives ‘text-based’ data transmission formats which is sometimes confusing - No intrinsic data type support - The XML syntax is redundant Now, you can easily determine between XML or JSON which is better suitable for you. #### Summarize this post with: ChatGPTPerplexityGrokGoogle AI **Stay Updated on AI** **Get Weekly AI Skills, Trends, Actionable Advice.** ##### Sign up for the newsletter Subscribe for Free You have successfully subscribed.
