FAQ
What does the JSON formatter do?
It takes your JSON data and reformats it with proper indentation for readability. It also validates the JSON and highlights any syntax errors.
What's the difference between Format and Minify?
Format (Beautify) adds indentation and line breaks for readability. Minify removes all whitespace to make the JSON as compact as possible, useful for reducing file size.
Is my data safe?
Yes. All processing happens in your browser. Your JSON data never leaves your device and is never sent to any server.
Is it free?
Yes, completely free with no limits. This tool runs entirely in your browser with no API calls.
