Frequently Asked Questions

What is JSON?

JSON (JavaScript Object Notation) is a lightweight data format used for storing and transporting data. It's easy for humans to read and write, and easy for machines to parse and generate.

What's the difference between format and minify?

Format (beautify) adds indentation and line breaks to make JSON readable. Minify removes all unnecessary whitespace to reduce file size, which is useful for production environments.

Why is my JSON invalid?

Common JSON errors include: using single quotes instead of double quotes, trailing commas, unquoted property names, or incorrect syntax. The validator will show you the specific error.

Can I format large JSON files?

Yes, but very large JSON files (over 1MB) may take longer to process and could impact browser performance. For extremely large files, consider using command-line tools.

Is my JSON data secure?

Your JSON data is processed securely on our server and is never stored or logged. However, avoid pasting sensitive credentials or personal information.
