FAQ

What is the difference between JSON and YAML?

JSON uses braces {} and brackets [] and is widely used in APIs and web development. YAML is indentation-based and commonly used for configuration files (Docker Compose, Kubernetes, etc.). Both can represent the same data, but YAML is generally more human-readable.

Is my data sent to a server?

No. All conversion happens locally in your browser via JavaScript. Your input data is never transmitted to any external server.

Can I convert large JSON files?

Yes. You can convert large JSON files as long as your browser has sufficient memory. However, very large files (tens of MB) may slow down the browser.
