Quick tips

Frequently Asked Questions

What does a JSON formatter do?
A JSON formatter makes JSON readable by adding indentation, spacing, and line breaks. It helps you debug, review API responses, and spot missing commas or brackets faster.
Will formatting JSON change the data?
No. Formatting only changes whitespace. Keys, values, and structure remain the same, so the formatted JSON represents identical data.
Why is my JSON not formatting?
Most failures happen because the JSON is invalid. Common issues include trailing commas, unquoted keys, single quotes instead of double quotes, or missing closing brackets.
Can I format large JSON files safely?
Yes. For very large JSON, formatting may take longer in the browser. If it feels slow, format smaller parts or remove extra fields before formatting.
Is this JSON Formatter secure?
Yes. This tool runs 100% client-side, so your JSON stays in your browser and is not uploaded to a server.
