FAQ

Is my JSON sent to a server?
No. All formatting and validation runs entirely in your browser using JavaScript. Nothing is uploaded.
What is the difference between formatting and minifying?
Formatting adds indentation and newlines so JSON is human-readable. Minifying removes all whitespace to reduce size, useful for production payloads.
Why does my JSON fail to parse?
Common issues are trailing commas, single quotes instead of double quotes, unquoted keys, or comments. Strict JSON does not allow any of those.
