❓ 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, and easy for machines to parse and generate. It's commonly used in APIs and configuration files.
How do I fix JSON syntax errors?
Common JSON errors include missing commas, trailing commas, unquoted keys, single quotes instead of double quotes, and unescaped special characters. Our validator will pinpoint the exact error location.
What's the difference between format and minify?
Formatting adds proper indentation and line breaks for readability. Minifying removes all unnecessary whitespace to reduce file size, useful for production environments.
Is my data secure?
Yes! All JSON processing happens entirely in your browser. Your data never leaves your computer and is not sent to our servers.
Can I validate large JSON files?
Yes, but very large files (>5MB) may slow down your browser. For optimal performance, we recommend files under 1MB.
