JSON Validator – Check JSON Syntax Online | MZ Smart Tools House
Validate JSON syntax locally and get a clear parsing error when the document is invalid.
Check whether text is valid JSON before using it in an API, config file or application.
How it works
Validation succeeds only when JSON.parse can parse the complete input.
Example
{"name":"Mujtaba"} is valid; {"name":"Mujtaba",} is not.
Frequently asked questions
Are single quotes valid JSON?
No. JSON strings and property names use double quotes.
Does validation modify my JSON?
No. It only reports whether parsing succeeds.
