Frequently Asked Questions

What is JSON?

JSON (JavaScript Object Notation) is a lightweight data interchange format that's easy for humans to read and write. It's language-independent and widely used for data exchange.

Why format JSON?

Formatting JSON makes it easier to read and debug by adding proper indentation and line breaks. It's essential for code review and development.

Is my data secure?

Yes, all processing is done locally in your browser. No data is sent to external servers, ensuring complete privacy and security.

What's the difference between formatting and minifying?

Formatting adds indentation and line breaks for readability, while minifying removes all whitespace to reduce file size for production use.

Can I validate large JSON files?

Yes, the tool can handle large JSON files. However, very large files may take longer to process depending on your browser performance.

What JSON data types are supported?

JSON supports strings, numbers, booleans, arrays, objects, and null values. All standard JSON syntax is fully supported.

How do I handle special characters in JSON?

JSON requires certain characters to be escaped: quotes (\"), backslashes (\\), and control characters. Use proper escaping or let the formatter handle it automatically.

What's the difference between JSON and JavaScript objects?

JSON is a text format with strict syntax rules (keys must be quoted), while JavaScript objects are code structures with more flexible syntax and can contain functions.
