YAMLCheck
A real YAML validator and toolkit. Check syntax, convert YAML to JSON, lint for style issues, and list top-level keys. Uses PyYAML when available, falls back to basic parsing when not.
Commands
| Command | Description |
|---------|-------------|
| yamlcheck validate | Validate YAML syntax β reports document count, types, key counts, file size. Falls back to basic tab/colon checks without PyYAML |
| yamlcheck to-json | Convert YAML to formatted JSON output. Handles multi-document YAML files |
| yamlcheck lint | Check for common style issues: tabs, trailing whitespace, Windows line endings, odd indentation, missing spaces after colons, long lines |
| yamlcheck keys | List top-level keys with types and value previews |
Requirements
python3 (required)PyYAML (optional β enables full parsing; install with pip3 install pyyaml)Without PyYAML, the tool still works but uses basic regex-based checks instead of full YAML parsing.
