JSON vs XML

For many years, XML (eXtensible Markup Language) was the standard for data exchange on the web. Today, JSON has largely replaced it. Why?

The Differences

Verbosity

XML is extremely verbose because it requires closing tags. JSON is much more compact.

Parsing

JSON maps perfectly to JavaScript objects, making it incredibly fast and easy to parse in the browser (JSON.parse()). XML requires a complex DOM parser.

Data Types

JSON natively supports strings, numbers, booleans, and null. In XML, everything is essentially a string unless defined otherwise by an external schema.

When to use XML?

XML is still heavily used in enterprise systems, configuration files, and document storage (like SVG or Microsoft Office files) where complex schemas and attributes are necessary.
