JSON / YAML Formatter

Format, validate, and beautify JSON & YAML

What is this tool?

Formats and validates JSON (or YAML) data, making dense or minified data readable with proper indentation, and flagging syntax errors.

How to use it

Paste your JSON or YAML, and it's automatically formatted with proper indentation. Any syntax errors are highlighted so you can fix them.

If you're debugging an API response that looks like a wall of text, pasting it here first to format and validate it is usually the fastest way to actually spot what's wrong with the data.
