Frequently Asked Questions

What is YAML?

YAML (YAML Ain't Markup Language) is a human-readable data serialization format. It's commonly used for configuration files in Docker, Kubernetes, Ansible, GitHub Actions, and many other tools. For simpler config files, TOML is a popular alternative.

Why is indentation important in YAML?

YAML uses indentation to define structure and hierarchy. Unlike JSON which uses braces, YAML relies on consistent spacing (usually 2 spaces). Incorrect indentation is the most common cause of YAML errors.

How do I convert YAML to JSON?

This validator parses your YAML and can output it in a normalized format. For JSON conversion, check our JSON Validator which can handle the converted data.

Is my data secure?

Yes, all validation happens locally in your browser. Your configuration files and secrets never leave your device.
