Format Helm values.yaml — Pretty-Print Values
Pretty-print a Helm values.yaml in your browser (single document). Roots that look like Kubernetes manifests (apiVersion + kind) are rejected — use format Kubernetes instead. Does not run helm template or render charts.
Developer notes
• Pretty-prints a single values.yaml document (rejects apiVersion+kind manifests). • Auto-format on paste/upload/sample; manual edits use the Format button (⌘↵). • YAML # comments are dropped by js-yaml — a soft warning appears when the input likely had comments. • Pair with format-kubernetes / validate-kubernetes.
Options
When teams pick this route
• Clean a messy values override before a PR. • Normalize indent across copied chart values. • Read nested image/replica blocks more easily. • Avoid pasting full manifests into a values formatter by mistake.

Helm values formatter FAQ
values.yaml only
Does it run helm template?
No. It only pretty-prints YAML. Chart rendering, hooks, and dependency updates are out of scope.
Why was my Deployment rejected?
Roots with both apiVersion and kind are treated as Kubernetes manifests. Use format Kubernetes for those files.
Multi-document values?
Not supported. Helm values.yaml must be a single mapping document.
beautify YAML vs this tool?
beautify YAML is the generic formatter. This tool adds Helm-oriented guards (single doc, reject manifest-shaped roots) and lives in the Kubernetes hub.
