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
INLINECODE0	Validate YAML syntax — reports document count, types, key counts, file size. Falls back to basic tab/colon checks without PyYAML
INLINECODE1

Convert YAML to formatted JSON output. Handles multi-document YAML files | | yamlcheck lint <file> | Check for common style issues: tabs, trailing whitespace, Windows line endings, odd indentation, missing spaces after colons, long lines | | yamlcheck keys <file> | List top-level keys with types and value previews |

Requirements

• - python3 (required)
• INLINECODE5 (optional — 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.
