JSON Formatter
Format, minify, and validate JSON in your browser.
Paste JSON to validate it, make it easier to read, or minify it for compact transport. Processing stays local to your browser.
How it works
The tool checks that the input is standard JSON before producing output. Formatting uses your selected indentation, while minifying removes unnecessary whitespace from the same JSON value.
Object member order is usually preserved in the output, but JSON consumers should not rely on object order for meaning. Comments, trailing commas, and other JSON5-style extensions are rejected because they are not valid JSON.
Input stays in the browser. Do not paste secrets into any web tool unless you are comfortable with the device and page context you are using.
