JSON Formatter
Open this when the payload is valid enough to parse but too messy to read. It pretty-prints or minifies JSON in the browser so you can copy the cleaned result back into your editor, request body, or ticket.
JSON Validator
Open this when the payload might be broken. It helps you catch invalid JSON before a parser, build step, or API request fails.

| Need | Why it matters |
|---|---|
| “I just need to read this payload” | Use the JSON Formatter to pretty-print or minify the output without leaving the browser. |
| “I think this JSON is broken” | Use the JSON Validator before you waste time debugging a syntax problem inside an API body or config file. |
| “I do not want to paste sensitive data into random sites” | Start with Why local code tools are safer if privacy is the main reason you opened this site. |
Start with the job in front of you
- API request body will not parse: open JSON Validator first so you fix syntax before you waste time reading a broken payload.
- Payload is valid but impossible to read: open JSON Formatter to pretty-print it, inspect nested keys, and copy the cleaned result back out.
- Unsure whether to validate or format first: read JSON Formatter vs Validator for the quick decision path.
- Payload contains tokens, customer data, or production details: read How to Format JSON Safely before you paste it anywhere.
Read one of these if the tool is not enough
- How to format JSON safely — use this when the payload may contain tokens, customer data, or production details.
- How to validate JSON before formatting — use this when you are not sure which job comes first.
- JSON formatter vs validator — use this when two tools sound similar and you want the fast answer.
- Why local code tools are safer — use this when privacy is the reason you are avoiding server-side tools.
