What is YAML?

YAML (YAML Ain't Markup Language) is a human-friendly format for configuration and data, common in Kubernetes, GitHub Actions, and Docker Compose files.

Question 2

Is YAML processed on a server?

Accepted Answer

No. Parsing and formatting run entirely in your browser so your files stay private.

Question 3

Can I convert YAML to JSON?

Accepted Answer

Yes. Use the YAML → JSON button, or paste JSON and use JSON → YAML for the reverse.

YAML is sensitive to indentation and reserved characters. Check colons in unquoted strings and consistent spaces for nesting.
