Frequently Asked Questions

How do I format JSON?

Paste minified or invalid JSON into our JSON Formatter, and it will pretty-print it with proper indentation and syntax highlighting. The formatter also validates your JSON and shows the exact line and character of any syntax errors.

What is the difference between JSON, YAML, and XML?

JSON is lightweight and native to JavaScript (used in APIs). YAML is human-readable with a whitespace-based structure (used in configs like Docker Compose, Kubernetes). XML uses tags like HTML and supports namespaces (used in SOAP, SAML, and legacy systems).

How do I convert JSON to CSV?

Use our JSON to CSV converter. It flattens a JSON array of objects into rows and columns. Each object key becomes a CSV column header. Nested objects are dot-notated (e.g., address.city).

What is JSON minification?

JSON minification removes all whitespace, line breaks, and indentation to reduce file size. A minified JSON file can be 20-40% smaller than formatted JSON. Use it for production API responses and config files where human readability isn't needed.
