❓ FAQ
Q: What is JSON?
JSON (JavaScript Object Notation) is a lightweight data-interchange format that's easy for humans to read and write and easy for machines to parse and generate. It's widely used for APIs and configuration files.
Q: Is my data safe?
Yes! This JSON formatter runs entirely in your browser. Your data never leaves your device, ensuring complete privacy and security.
Q: What's the difference between Format and Minify?
Format (or beautify) adds proper indentation and line breaks to make JSON readable. Minify removes all unnecessary whitespace to reduce file size, ideal for production use.
Q: Can I validate JSON files?
Yes! You can paste JSON from any file, and our validator will check the syntax and highlight any errors. We support JSON files of any size.
