JSON Formatter

What Can Our JSON Formatter Do?

Our free online JSON formatter provides everything you need to work with JSON data efficiently. From basic formatting to advanced features, we’ve got you covered.

• Format & Beautify: Transform minified, compacted, or poorly formatted JSON into clean, indented code. Choose your preferred indentation: 2 spaces, 4 spaces, or tabs.
• Validate Instantly: Not sure if your JSON is valid? Our formatter checks syntax as you paste or type. Invalid JSON? We’ll tell you exactly what’s wrong and where.
• Minify JSON: Need to compress JSON for production? One-click minification removes all whitespace and line breaks to create the smallest possible file size.
• Syntax Highlighting: Color-coded keys, values, strings, numbers, booleans, and nulls make scanning your data effortless.
• Copy to Clipboard: One click to copy your formatted (or minified) JSON. Ready to paste wherever you need it.
• JSON to Tree View: Visualize nested JSON structures as an interactive tree. Expand and collapse objects and arrays with a click.
• Sort Keys Alphabetically: Keep your JSON consistent. Sort all keys in alphabetical order with a single click.
• Escape/Unescape Strings: Handle special characters properly. Escape raw strings for safe JSON output or unescape for human reading.

When to Use a JSON Formatter?

• Debugging APIs: Using third party APIs? They don’t always look nice in their answers. Simply copy and paste the raw JSON response into our formatter and you’ll instantly see the structure, nested relationships and be able to find the field you need.
• Files: Over time configuration files develop formatting errors. Prepare them all in a single format and get your project in order.
• Learning JSON: New to JSON? The syntax-highlighted, indented output makes it easy to understand how data structures work – particularly when comparing with the formatted vs. minified versions.
• Data Analysis: With JSON datasets, readable format makes it easy to identify patterns and anomalies not seen in compressed data.
• Collaborative Development: Formatted code is easier to comment on, read, and find errors in when sharing snippets with teammates.
