About JSON Formatter and Validator
The tool indents JSON so it is easy to read. If it is invalid, the error is shown. Common mistakes: a trailing comma, single quotes, unquoted keys. Because it runs locally, you do not send sensitive data to a server.
Example
Input
{"ad":"Ali","yas":30,"hobiler":["kod","müzik"]}Result
{
"ad": "Ali",
"yas": 30,
"hobiler": [
"kod",
"müzik"
]
}FAQ
What does the error message mean?
It points to the approximate position and the unexpected character in the JSON.
Are my files uploaded to a server?
No. Everything runs in your browser; your files and text never leave your device.
Is it free? Do I need an account?
The tool is free and needs no registration.
Does it work on a phone?
Yes, in modern desktop and mobile browsers; large files depend on your device power.
