❓ Frequently Asked Questions

Is my JSON data sent to any server?

No. All processing happens entirely in your browser using JavaScript. Your JSON data never leaves your device.

What is JSON formatting?

JSON formatting (beautifying) adds proper indentation and line breaks to make JSON data human-readable. Supports 2-space, 4-space, 8-space, and tab indentation.

What does JSON minification do?

Minification removes all unnecessary whitespace and line breaks from JSON, reducing file size for faster data transfer in APIs and web applications.

Can I upload a JSON file?

Yes! Click the Upload button to load a .json or .txt file directly. You can also download the formatted output as a JSON file.
