JSON & YAML Cheat Sheet (Printable PDF)

For the config that's valid and still wrong.

Use it when: a config parses but behaves differently than it reads, you need to reshape JSON with jq, YAML indentation breaks a deploy.

On the sheet: syntax, parsing and transformation with jq and yq.

Not on it: schema validation tooling.
