Paste YAML here, or drop a .yaml or .yml file.

YAML Formatter & Viewer

Paste YAML to reformat it with consistent indentation and syntax highlighting: config files, CI pipelines, Kubernetes manifests, Helm values or OpenAPI specs.

What you get

• Re-indented by Prettier, keeping your comments and ----separated documents.
• Indentation you choose (Settings → Tab size).
• Collapsible mappings and lists in the output.
• Kubernetes CustomResourceDefinitions also open as browsable schema documentation.

Good to know

Input that isn't valid YAML is shown as-is rather than formatted. YAML doesn't allow tabs for indentation, so a tab-indented file won't format until the tabs are spaces.
