Worked Example

Paste minified JSON such as {"name":"EZPZTool","active":true,"tags":["pdf","image"],"meta":{"size":2048}} into the input and press Format. The tool indents it into a readable tree, color-codes keys and values, and makes the nesting obvious at a glance. Need a compact payload for storage or a log line? Press Minify to collapse it back to a single line. If you paste a truncated response such as {"name":"EZPZ... the validator flags the exact problem instead of silently showing partial output.

Frequently Asked Questions

• Does it validate JSON?▾
  Yes. Invalid JSON will show an error message indicating the problem.
• Can I minify JSON as well?▾
  Yes. The Minify button collapses formatted JSON back into one compact line, which is handy for storing payloads or writing single-line log output.
• Why is valid-looking JSON rejected?▾
  Strict JSON disallows trailing commas, single quotes, and unquoted keys - common habits from JavaScript or YAML. The validator points at the offending position so you can fix it quickly.
• Can I change the indentation?▾
  Yes. You can pick the indentation width used for pretty-printing so the output matches your team's style, for example two spaces.
