Frequently Asked Questions

What is JSON formatting?▼

JSON formatting (or beautification) is the process of adding indentation and line breaks to compact JSON data, making it readable by humans. It helps developers debug and understand JSON structures more easily.

Is my data safe?▼

Yes! All processing happens entirely in your browser using JavaScript. Your JSON data is never sent to any server. You can even use this tool offline once the page is loaded.

What is the maximum JSON size supported?▼

This tool can handle JSON files up to 10MB. For larger files, you may experience slower performance depending on your device capabilities.

What is the difference between formatting and minifying?▼

Formatting adds whitespace and line breaks to make JSON human-readable, while minifying removes all unnecessary whitespace to reduce file size for production use.
