Validate pasted YAML and format it with consistent indentation using a local browser parser.
This tool validates pasted YAML and rewrites it with consistent indentation. It is useful for config files, CI snippets, front matter and Kubernetes-style examples.
Output
Format mode returns copy-ready YAML. Validate mode returns a compact validity message while keeping any parser warnings or errors separate from the copied result.
Scope
The calculator uses a local js-yaml library from /libs/. Application-specific schema validation is not included.
