Frequently Asked Questions
Why does my JSON show an error?
JSON is strict. Common errors include trailing commas, single quotes (must be double), or unquoted keys. Our tool identifies these issues specifically to help you fix them.
What is the difference between specific formatting options?
Prettify adds indentation (2 spaces) and newlines for human readability. Minify removes all unnecessary whitespace to make the payload as small as possible for API transmission.
Is my data safe?
Absolutely. Formatting happens 100% in your browser using JavaScript's native JSON engine. No data is sent to any server.
