XML and JSON are two different content types that are used for the interchange of data between different systems.
JSON is a javascript simple object model that contains key and value types. It is the lightweight data format used in REST API and Microservices. It is easily readable by humans and machines.
JSON simple example
const jsondata = {
"name": "john",
"email":"[email protected]"
}
XML is a start and end tag, and the validation is based on XML Schema. It provides many features, used in Service Oriented Architecture with SOAP Protocols. It is complex to understand humans.
Example xml
<users>
<user id="1">
<name>Eric<name>
<salary>4000</salary>
</user>
</user>
