Frequently Asked Questions

What is JSON?

JSON (JavaScript Object Notation) is a lightweight data-interchange format. It is easy for humans to read and write and easy for machines to parse and generate.

Why should I use a JSON Formatter?

Raw JSON data is often minified (compressed) to save space, making it hard to read. A JSON Formatter beautifies this data with proper indentation and spacing, making it easier to debug and understand.

Is my data safe?

Yes, all formatting is done client-side in your browser. Your data is never sent to our servers.
