About the JSON Formatter
Beautify minified JSON into a readable, indented structure, or minify formatted JSON into a compact single line for production use.
Formatting happens instantly in your browser — API responses and config files containing secrets are never sent anywhere.
Frequently asked questions
Is my JSON sent to a server?expand_more
No — parsing and formatting run entirely in your browser, which makes the tool safe for data containing tokens or credentials.
What is the difference between beautify and minify?expand_more
Beautify adds indentation and line breaks so humans can read the structure; minify strips all whitespace to make the payload as small as possible.
What happens if my JSON is invalid?expand_more
The tool shows the parser’s error message so you can find and fix the problem — try the JSON Validator for focused error checking.
