JSON formatter and validator
Validate, beautify and minify JSON.
How to use: json formatter and validator
Paste your JSON to validate it and give it a readable, indented format, or minify it to save space. If there is a syntax error we tell you what went wrong. Everything happens in your browser: your data is not sent anywhere.
What are the typical JSON errors?
Trailing commas, single quotes instead of double quotes, unquoted keys or comments, which JSON does not allow.
Is it safe to paste private data?
Yes, processing happens in your browser and nothing is sent to a server.
