Question 1

Does it validate YAML as well?

Accepted Answer

Yes. The formatter parses your input first; if the YAML is invalid, an error message is shown instead of formatted output.

Question 2

What indent options are available?

Accepted Answer

2 spaces or 4 spaces.

Question 3

Is my YAML stored anywhere?

Accepted Answer

No. All processing happens in your browser; nothing is sent to a server.

Question 4

What is YAML?

Accepted Answer

YAML (YAML Ain't Markup Language) is a human-readable data serialisation format commonly used for configuration files, CI/CD pipelines (GitHub Actions, GitLab CI), Kubernetes manifests, and application settings.

Question 5

Why format YAML?

Accepted Answer

Proper indentation is critical in YAML because the structure is whitespace-sensitive. A formatter ensures consistent indentation throughout the document, helping you avoid hard-to-spot parsing errors.
