❓FAQ
Q: What is JSON?
A: 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?
A: 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?
A: 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?
A: 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.
