YAML to JSON

Indentation to brackets. For when you need to be explicit.

What this does

DEVS: js-yaml load() with safe schema. No custom types, no code execution. Outputs formatted JSON. Client-side only.

Paste YAML, get JSON. Comments are dropped (JSON doesn't support them). Anchors and aliases are resolved into actual values.

Common use cases

Validating YAML structure by converting to strict JSON. Feeding YAML configs into JSON-based tools. Debugging Kubernetes manifests by making nesting explicit with brackets.

Things to know

YAML allows things JSON doesn't: comments, anchors, multi-line strings, unquoted keys. All of these are handled during conversion. YAML's indentation sensitivity is its biggest gotcha. If the output looks wrong, check your indentation. Uses the safe schema, so no custom types.

Privacy

Parsed and converted in your browser. Your YAML files stay local.
