Format JSON, validate syntax errors and minify payloads in one place. Useful for API responses, config files and debugging nested objects.
Formatted JSON will appear here...
{"name":"John","age":30}
Formatted output:
{
"name": "John",
"age": 30
}
Use this JSON formatter when you need to inspect API responses, clean up minified payloads, validate copied JSON before deploying configuration changes or compare readable data structures during debugging.
A JSON formatter converts raw JSON data into a readable structure. It helps developers debug APIs, understand data and work with JSON more efficiently.
Formatted JSON makes nested objects easier to read and helps detect syntax errors quickly. This tool is commonly used when working with APIs and data processing.
Can I use this to validate broken JSON?
Yes. Paste the payload and use the formatter to catch invalid commas, quotes or brackets before using the JSON elsewhere.
Does this tool store my data?
No. Formatting and validation run locally in your browser.
