Frequently Asked Questions
- What is a JSON formatter?
- A JSON formatter takes minified or messy JSON and rewrites it with consistent indentation and line breaks so it's easier to read and debug. It can also validate that your JSON is syntactically correct.
- Is my JSON data sent to a server?
- No. This JSON formatter runs entirely in your browser. Your data never leaves your device — we don't store, log, or transmit what you paste.
- Can I minify JSON here too?
- Yes. You can format (prettify) JSON with custom indentation or minify it to a single line to reduce file size for APIs or configs.
