Yamlcheck

YAMLCheck 是一个命令行工具，通过 python3 对 YAML 文件执行语法校验、风格 lint、顶层键列举和 YAML 转 JSON。优先使用 PyYAML 完整解析，缺少该库时退回基于正则的基础检查，并支持多文档 YAML 文件。

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 <file>`	Validate YAML syntax — reports document count, types, key counts, file size. Falls back to basic tab/colon checks without PyYAML
`yamlcheck to-json <file>`	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)
PyYAML (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.

Examples

# Validate a docker-compose file
yamlcheck validate docker-compose.yml

# Convert YAML config to JSON
yamlcheck to-json values.yaml

# Check for style issues
yamlcheck lint playbook.yml

# See what keys are defined
yamlcheck keys config.yaml
