Difference Between JSON and XML (With Table)

JSON (JavaScript Object Notation) is a software program that is used in the creation of web content by transferring data, while XML (Extensible Markup Language) is encryption software. Both of these are used to encrypt various forms of language to communicate between the browser and the server.

JSON is based on JavaScript, while XML is more of an HTML-like application. They both work by coding and decoding the encryption. They play a crucial role in the complex field of web creation and programming languages. Both are widely used for language encryption all over the world.

JSON vs XML

The difference between JSON and XML is that JSON is an open standard file format used for data transfer and XML is a markup language used to keep the data in a structural and organized manner. JSON has a file format of a data interchange, and the XML has a markup language file format. JSON is based on JavaScript, and XML is based on Standard Generalized Markup Language.

JSON stands for JavaScript Object Notation and is used in the case of transmittance of data on the internet in a parseable manner. It is in a highly data-oriented format. It has an open standard file format and a data interchange format. JSON uses human-readable text for the purpose of storing and transmitting data. It is independent of language, and nowadays, many programming languages include code to generate and parse JSON format data.

XML stands for Extensible Markup Language and keeps the data in a structural manner. XML is more like a document-oriented format. XML is a derivative of SGML(Standard Generalized Markup Language), and it basically defines a set of rules followed by its usage in encoding documents in such a format that is both machine-readable as well as human-readable. It provides a base language for many other communication protocols, such as in the case of XMPP(Extensible Messaging and Presence Protocol).

What is JSON?

JSON stands for JavaScript Object Notation. It is used for communicating between browser and server and has an open standard file format. The data format of JSON is independent of languages and hence easy to read by humans. JSON has the file extension of .json and is used for the storage of information, and is organized having an easy-to-access manner. The data collected is easily and logically accessible and readable by humans.

JSON is a lightweight data-interchange format. It is language-independent and is based on the programming language called JavaScript. JSON is easy to generate and easier to understand.

Example,

{ “Geeks” : [

   {“firstName”:“Sakshi”, “lastName”:”Sharma”}

]}

JSON offers a very high-level façade which simplifies the commonly used use-cases. JSON is fast as it uses very little space and is used in cases of large graphic files. The library of JSON is an open-source library, and anyone can use it free of cost. Also, the JSON library is independent of any other libraries making its file easily readable.

What is XML?

XML stands for Extensive Markup Language and is case sensitive. XML is not used for displaying data but rather to carry or transfer the data. It is a markup language that defines a specific set of rules for the documents to be encoded. The language is in a format which is understandable by both machine and humans. It basically focuses its design on generality, simplicity, and usability on the internet. The file extension for XML files is .xml, and the basic unit is known as an element.

It is presented in a textual data format. The design focuses on the documents and is also used for arbitrary data structure representation as in cases of web series.

Example,

<Geeks>

   <Geek>

     <firstName> Sakshi</firstName> <lastName>Sharma</lastName>

   </Geek>

</Geeks>

XML does not have predefined tags, and one has to use customized tags. XML is used to carry data files and does not allow the displaying of data. It has a markup language that is easily understandable by humans. The XML is also an extensive markup language, just like HTML and its file format is easy to read and write.

Main Differences Between JSON and XML

  1. JSON doesn’t use end tags, while XML uses both start and end tags.
  2. JSON is comparatively shorter than XML.
  3. JSON is quicker to read and write as it can be parsed more easily than XML.
  4. While JSON can be parsed by any of the JavaScript languages, XML is parsed using the XML parser.
  5. JSON types include strings, array, number, Boolean, while XML data must be a string.
  6. JSON is supported by most browsers and is easy to read, while cross-browser XML parsing is tricky enough.
  7. XML has data display capability owing to being a markup language, while JSON lacks this feature.
  8. While only text and number data type is supported by JSON, the XML can support text, charts, numbers, graphs, images, etc.

Conclusion

Both of the languages are self-describing. That is, it is readable by humans. Both are hierarchical and can be parsed and used by programming languages. Both of them are used in content creation and are widely used all over the world. Both of them have some similarities, and the comparison based on their respective features and benefits indicates the usage according to the need of the programmer.

In the end, if one needs to exchange data only and does not care about semantics or validation, JSON should be used. However, learning XML and related technologies along with JSON is needed to achieve more than just data exchange and quick processing. JSON has to make a lot of updates and has fewer features when compared to XML.
