About this tool
Format and validate JSON — beautify it with indentation to read easily, or minify it to one line. Errors are highlighted so you can spot problems fast.
Frequently asked questions
Does it validate my JSON?
Yes — invalid JSON shows an error message so you can fix it.
Can it minify JSON?
Yes — one click removes whitespace for a compact single line.
Is my data private?
Yes — it's processed in your browser.
