What is JSON?
JSON (JavaScript Object Notation) is a lightweight text format that stores structured data in a human-readable format. JSON data takes up less space than XML, is easier to read for humans, and is easier to process for computers. JSON is frequently used in network communications between clients and servers. JSON is a format that originated from JavaScript but is now used by almost all programming languages, including PHP, Python, Java, C++, C#, and Go, and many of them have built-in modules for working with JSON data.
What is XML?
XML (eXtensible Markup Language) is an open data format designed for storing, structuring, and transmitting data using human-readable text. XML is a widely used data format for storing and transferring data objects over the network, during client-server interactions. The language markup of XML is similar to HTML. XML is independent of programming languages, software, and hardware, and can be easily parsed into syntactic constructs by XML processors. XML is an informative and simple format. XML files are MIME type application/xml. An XML file has the extension *.xml.
