            <h2>What is JSON Formatter?</h2>
            <p>A JSON formatter (also called JSON beautifier or pretty-printer) takes minified or poorly formatted JSON data and formats it with proper indentation and line breaks for easy reading. It's one of the most frequently used developer tools.</p>
            <p>Our JSON Formatter not only beautifies your JSON but also validates it, highlighting syntax errors and their locations. It helps you quickly identify missing commas, brackets, or other common JSON issues.</p>
            <p>Whether you're debugging API responses, inspecting configuration files, or reviewing data structures, properly formatted JSON is dramatically easier to read and understand.</p>
