Input YAML

# Kubernetes Deployment for checkout-api apiVersion: apps/v1 kind: Deployment metadata: name: checkout-api labels: app: checkout spec: replicas: 3 selector: matchLabels: app: checkout template: metadata: labels: app: checkout spec: containers: - name: api image: registry.example/checkout:2.4.1 ports: - containerPort: 8080

Minified YAML

apiVersion: apps/v1 kind: Deployment metadata: {name: checkout-api, labels: {app: checkout}} spec: {replicas: 3, selector: {matchLabels: {app: checkout}}, template: {metadata: {labels: {app: checkout}}, spec: {containers: [{name: api, image: registry.example/checkout:2.4.1, ports: [{containerPort: 8080}]}]}}}

Options

Remove Comments
When true, all # comments are stripped. When false, full-line # comments are kept and the YAML structure is still compacted.

Full-line # comments are kept when false; inline # comments are still dropped by parse

String Quotes
Minimal or double-always quoting on dump.

YAML conversion helpers

Use JSON → YAML, YAML → JSON, YAML → XML or YAML → CSV for format conversion.
