Overview
About YAML Validator
YAML Validator checks common YAML formatting problems such as odd indentation, tabs and missing spaces after colons. It is useful for config files, CI settings, deployment snippets and documentation examples. YAML can be strict, so use this as a quick pre-check and still test the file in the system that will read it.
