About this tool
The JSON Formatter beautifies JSON with consistent indentation, making it easier to read and debug. It can also minify JSON to reduce its size, and validate JSON syntax with a clear error location when something is wrong.
Frequently asked questions
Is my JSON sent to a server?
No, formatting and validation happen entirely in your browser using the built-in JSON parser.
How do I fix an error shown by the validator?
The error message includes the line and column number where the parser stopped, which usually points to a missing comma, quote or bracket.
Can I minify JSON as well as format it?
Yes, use the Minify button to remove all unnecessary whitespace.
