Format, Validate & Minify JSON
JSON (JavaScript Object Notation) is the standard data format for APIs, configuration files, and data exchange. Raw JSON from an API or log file is often minified (no whitespace) and difficult to read. This formatter adds proper indentation so you can quickly inspect the structure. It also validates the JSON and highlights any syntax errors.
The minify mode does the opposite — removing all unnecessary whitespace to reduce payload size, useful before committing config files or sending data over a network. Toggle between formatted and minified views with one click. All processing happens client-side, making it safe for sensitive API responses — nothing leaves your browser.
