Question 1

What is a JSON formatter?

Accepted Answer

A JSON formatter (also called a JSON beautifier) takes compact or minified JSON and adds proper indentation and line breaks, making it easy to read and debug.

Question 2

How do I validate JSON?

Accepted Answer

Paste your JSON into the input box and click 'Validate'. If the JSON is valid, you'll see a confirmation. If not, an error message shows exactly where the problem is.

Question 3

What does JSON minify do?

Accepted Answer

Minifying JSON removes all whitespace, indentation, and line breaks to make the JSON string as compact as possible — useful for APIs and storage.

Question 4

Is my data sent to a server?

Accepted Answer

No. All formatting, minifying, and validation happens entirely in your browser using JavaScript. Your data never leaves your device.
