Frequently Asked Questions

What is YAML?

YAML (YAML Ain't Markup Language) is a human-readable data format commonly used for configuration files. It uses indentation to represent structure, making it easier to read than JSON.

Why use YAML over JSON?

YAML is more readable for configuration files, supports comments, and requires less punctuation. JSON is better for APIs and data interchange due to wider support and faster parsing.

Is my data safe?

Yes. All conversions happen locally in your browser. We don't store, log, or transmit your data to any server.
