XML Schema vs. JSON Schema: What to Use?

JSON schema or XML? What to use?

Which one is faster? Which of the two is the best for my project? Well according to experts, they both are effective tools to use for your project. What most people do not understand is that both of them are not comparable, and their variance is as wide as comparing a supercar and a mountain bike. They both get you home at the end of the day. JSON and XML Schema are very different, and both have varied areas of applicability.

What is XML Schema?

The XML Schema is a World Wide Web consortium recommendation that normally works by specifying how to formally describe the elements in an Extensible Markup Language document or XML. This kind of description can be used to authenticate that each item of the content created is a document adheres to the description of the element in which the content is to be placed. The XSD or XML Schema was approved by W3c standard back in April 2012.

What is JSON?

JSON or the JavaScript Object Notation is minimal but readable format that’s used for structuring data. Its main function is to transmit data between a server and a web application as a substitute to XML Schema. Users will use JSON to organize and store their website content created with the CMS.

What is the Difference between XML and JSON?

Both JSON and XML are tools that can be able to transmit the same kind of date, making them almost incomparable. However, the better option largely depends on what the user requires it for.


XML has better tooling functionality that can be used for verifying Schema. It also has built in support for namespaces and can be more easily restructured into HTML. XML can also be queried using XPath that is an exceptional query language.


JSON has pretty printers, and in most user’s experience, it makes it much better and easier for humans to use. It also has the best format, especially when one end of the transfer is written in JavaScript. JSON has almost no legacy, meaning, this means that the chances of being forced to work with malformed JSON are minimal.  

It’s hard to make a comparison of the best choice between the two since one can be used to store anything that can also be stored in the other. This leaves us with usability and tooling, the only criteria that they can be distinguished from best use.

Our verdict lies with JSON, and we've built a handy dandy JSON schema generator for your site!
