Frequently Asked Questions

What does this show that the YAML Formatter doesn't?▾

It shows the parsed structure as a collapsible tree, rather than reformatted YAML text — useful for understanding a document's shape at a glance.

What YAML features are supported?▾

Anything js-yaml's default schema supports: nested maps and sequences, anchors/aliases, multi-line strings, and standard scalar types.

Is my YAML uploaded anywhere?▾

No — parsing runs entirely in your browser via js-yaml.
