JSON vs XML

What is JSON?

JSON is a file format for storing and sending data objects with attribute-value pairs and arrays that employ human-readable text. JSON is a standard for storing data that is well-organized and accessible. JavaScript Object Notation (JSON) is an acronym for JavaScript Object Notation. It provides a logically accessible collection of data that is human-readable.

What exactly is XML?

XML is a data-storage-oriented extensible markup language. It is commonly used for data transport, and there is a case difference. You can use XML to define markup elements and create your markup language. An element is a fundamental unit in the XML language, and The.xml file extension is used for XML files.

KEY DIFFERENCE

  • JSON objects have a type, whereas XML data is typeless.
  • JSON does not provide namespace support, while XML provides namespaces support.
  • JSON has no display capabilities, whereas XML offers the capability to display data.
  • JSON is less secure, whereas XML is more secure compared to JSON.
  • JSON supports only UTF-8 encoding, whereas XML supports various encoding formats.

History of JSON

  • XML data is typeless, but JSON objects have a type.
  • JSON does not support namespaces; however, they are supported by XML.
  • JSON does not support data visualization, whereas XML does.
  • JSON is less secure when comparing JSON to XML, but XML is more secure.
  • JSON only accepts UTF-8 encoding, but XML accepts a variety of encoding schemes.

History of XML

  • The following are significant milestones in the history of XML:
  • SGML was also the source of XML.
  • In February 1998, XML version 1.0 was released.
  • IETF Proposed Standard: XML Media Types (Jan 2001)
  • The Extensible Markup Language (XML) stands for "Extensible Markup Language."
  • GML was created in 1970 by Charles Goldfarb, Ed Mosher, and Ray Lorie.
  • Sun Microsystems pioneered the invention of XML in 1996.

Features of JSON

  • Simple to use — JSON API has a high-level facade that makes it easier to simplify typical use-cases.
  • Performance - JSON is quite quick because it uses very little memory, ideal for big object graphs or systems.
  • JSON library is an open-source and free-to-use tool.
  • It is unnecessary to construct a mapping because the Jackson API provides default mapping for many serialized items.
  • Clean JSON — Produces a readable, clean, and compliant JSON result.
  • Dependency — The JSON library does not require any other libraries to handle data.

Features of XML

  • There are no predefined XML tags. You must create your customized tags.
  • XML was created to transport data, not to display it.
  • The XML markup code is simple to comprehend for a human.
  • On the other hand, the structured format is simple to read and write from programs.
  • XML, like HTML, is a markup language that may be extended.

Here is the prime difference between JSON vs XML:

JSON XML
A type is assigned to a JSON object. The data in XML is typeless.
String, number, array, and Boolean are all JSON types. All XML data should be converted to strings, and XML data must be parsed.
As JSON objects, data is easily accessible. XML parsing across browsers can be difficult.
The majority of browsers support JSON. Because XML is a markup language, it has the ability to show data.
JSON has no means of displaying data. Numbers, text, photos, charts, graphs, and other data kinds are supported by XML.
Only text and integer data types are supported by JSON. It also has options for translating the data's structure or format to actual data
It's simple to find value. It's difficult to find value.
Many Ajax toolkits support it. The Ajax toolbox does not provide complete support.
Deserializing/serializing JavaScript in a totally automated manner. To serialize/de-serialize from XML, developers must write JavaScript code.
Object support is built-in. Conventions must be used to express the object - most commonly, properties and elements are overlooked.
Only UTF-8 encoding is supported. It can be encoded in a variety of ways.
It does not allow for comments. It accepts feedback.
When compared to XML, JSON files are much easier to read. The reading and interpretation of XML texts is more complicated.
There is no support for namespaces in this version. Namespaces are supported.
It isn't as safe. It has a higher level of security than JSON.
