JSON vs XML: Differences

Board Infinity -

What is JSON?

JSON is a file format that employs language that can be read by humans to store and send data objects with arrays and attribute-value pairs. JSON is used to store data in a structured, accessible manner. JavaScript Object Notation, or JSON. It provides a logically accessible, human-readable collection of data.

What is XML?

The extensible markup language XML was created with the purpose of storing data. It is frequently used for data transport. Case makes a difference. You may specify markup components and create unique markup languages using XML. In the XML language, a fundamental unit is called an element. The XML file extension is.xml.

Features

JSON

  • Simple to use - JSON API provides a high-level façade that makes it easier for you to streamline frequently used use cases.
  • Performance - JSON is fairly quick and requires relatively little memory, making it ideal for big object graphs or systems.
  • JSON library is an open-source, cost-free utility.
  • doesn't need to be created because the Jackson API already has default mapping for a lot of the objects that will be serialized.
  • Pure JSON - produces easy-to-read, clean, and compatible JSON results.
  • Dependency: The JSON library processes data without the need for any other libraries.

XML

  • There are no predefined XML tags. You must provide your personalized tags.
  • XML was created to transport data, not to be used for data visualization.
  • An individual may easily grasp the markup code in XML.
  • The structured format, on the other hand, is simple to read and write from programs.
  • Like HTML, XML is an extensible markup language.

Comparison table

JSON

XML

JSON objects are typed.

Data in XML is typeless.

JSON types: string, number, array, Boolean

Data in XML should only be strings.

Data may be accessed easily as JSON objects.

Data from XML must be parsed.

The vast majority of browsers support JSON.

XML parsing across browsers may be challenging.

JSON is incapable of being shown.

Due to the fact that XML is a markup language, it has the capacity to display data.

Only text and integer data types are supported by JSON.

Numerous data kinds, including text, photos, graphs, charts, and numbers, are supported by XML. It also offers possibilities for integrating actual data with the structure or format of the data.

Finding value is simple.

Finding value again is challenging.

backed by several Ajax toolkits

Ajax Toolkit does not provide complete support

for a completely automatic process for serializing and deserializing JavaScript.

JavaScript code must be written by developers to serialize and de-serialize data from XML.

support for objects natively.

Conventions must be used to express the object, most commonly by omitting the usage of attributes and components.

Only the UTF-8 encoding is supported.

It is capable of different encoding.

Comments are not supported.

It backs up statements.

Compared to XML, JSON files are simpler to understand.

XML texts are somewhat more challenging to read and understand.

Namespaces are not supported in any way.

Namespaces are supported.

Less security exists.

Over JSON, it is more secure.

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

<?xml version="1.0" encoding="UTF-8" ?>

<root>

<student>

<id>01</id>

<name>Tom</name>

<lastname>Price</lastname>

</student>

<student>

<id>02</id>

<name>Nick</name>

<lastname>Thameson</lastname>

</student>

</root>

Advantages of JSON

The following are some significant advantages of utilising JSON:

  • Support each and every browser
  • Easily readable and written
  • simple syntax
  • Using the eval() method, JavaScript can natively parse.
  • Simple to build and control
  • supported by all significant JavaScript frameworks
  • most backend technologies are in support of
  • JavaScript natively understands JSON.
  • It enables network-based serialization and transmission of structured data.
  • It is compatible with contemporary programming languages.
  • Any JavaScript object may be transformed into JSON text, which can then be sent to the server.

Advantages of XML

Using XML has the following advantages and drawbacks:

  • Enables the transfer of documents across systems and applications. You can swiftly communicate data between multiple systems with the aid of XML.
  • HTML is separated from the data via XML.
  • Platform modification is made easier with XML.
  • Allows for the creation of custom tags.
