Frequently Asked Questions

What is a JSON Formatter?
A JSON formatter takes raw or minified JSON data and adds proper indentation, whitespace, and line breaks to make it human-readable. It also validates whether your JSON is syntactically correct.
Is my data safe?
Yes! Everything runs 100% in your browser using JavaScript. Your JSON data is never sent to any server. It's completely private and secure.
What's the difference between formatting and minifying?
Formatting adds whitespace and indentation to make JSON readable for humans. Minifying removes all unnecessary whitespace to reduce file size — ideal for production APIs and data transmission.
What does "Sort Keys" do?
Sort Keys alphabetically orders all object keys in your JSON. This makes it easier to find specific properties and compare JSON objects.
