JSON vs. XML vs. YAML: Which Format Should You Use?

JSON

Lightweight and easy to parse, JSON is the standard for REST APIs and web applications. Its simple key-value syntax is native to JavaScript, making it the go-to format for frontend and backend communication.

XML

More verbose but highly extensible, XML supports attributes, namespaces, and schemas. It remains common in enterprise systems, SOAP APIs, and document-heavy workflows like RSS feeds and SVG graphics.

YAML

The most human-readable of the three, YAML is popular for configuration files such as Docker Compose, Kubernetes manifests, and CI/CD pipelines. It uses indentation instead of brackets.

Our JSON tool lets you convert between all three formats using the Export feature in the toolbar.

Pro Tip: Need to compare two different JSON files? Use our Diff Checker to see the changes side-by-side. You can also use the Token Counter to analyze your JSON payload size for API limits.
