JSON (JavaScript Object Notation) is the most widely used data interchange format on the web. APIs, configuration files, databases, and web applications all rely heavily on JSON. When working with API responses or minified JSON data, the output is often compressed into a single line, making it extremely difficult to read and debug.
Our JSON formatter takes compressed or poorly formatted JSON and transforms it into a clean, properly indented structure that is easy to read and understand. It also validates your JSON syntax, catching common errors like missing commas, unmatched brackets, or invalid characters before they cause problems in your application.
Transform minified JSON into beautifully indented, readable format instantly.
Catch syntax errors like missing commas, brackets, and invalid values.
Choose between 2 spaces, 4 spaces, or tab indentation to match your code style.
Copy formatted JSON to clipboard instantly for pasting into your code editor.
Common use cases include debugging API responses, preparing JSON configuration files, formatting data received from databases, cleaning up JSON payloads for documentation, and validating JSON before submitting it to services. Our tool handles all these scenarios with precision and speed.
