Frequently Asked Questions

What is JSON?

JSON (JavaScript Object Notation) is a lightweight data interchange format. It's easy for humans to read and write, and easy for machines to parse. JSON is used in APIs, configuration files, and data storage.

How do I format minified JSON?

Paste your minified JSON into this tool and it will automatically format it with proper indentation. You can toggle between formatted and minified views, and copy the result.

What is the difference between JSON and JavaScript objects?

JSON is a text format with strict rules: keys must be double-quoted, no trailing commas, no comments, and no undefined values. JavaScript objects are more flexible and support functions, symbols, and other features.

How do I validate JSON?

Paste your JSON into this tool - if it's invalid, you'll see an error message explaining the problem. Common errors include missing quotes, trailing commas, and unescaped special characters.
