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.

FAQ — Minify YAML

Minification

Are # comments preserved?

When removeComments is false, full-line # comments are kept at the top. Inline # comments are still dropped by parse.

Beautify YAML?

See YAML beautifier — comments cannot survive parse.
