Format JSON without losing clarity
Formatted JSON makes nested data easier to inspect, review, and share. This tool validates the text first, then applies consistent indentation. Use minify when you need compact JSON for a request or configuration value.
Check errors before sharing
Invalid JSON commonly comes from missing commas, unmatched braces, unquoted keys, or trailing commas. The error message is shown directly below the editor so you can correct the input without losing your place.
Your data stays in the browser
Formatting happens on this page. Still, avoid pasting credentials, tokens, or production secrets into any shared environment. Redact sensitive values before using data in a bug report or documentation.
