YAML Validator & Converter

YAML (YAML Ain't Markup Language) is a human-friendly data serialization standard widely used for configuration files in tools like Docker Compose, Kubernetes, GitHub Actions, Ansible, and many others.

Features

YAML → JSON: Parse YAML and output minified or pretty-printed JSON
JSON → YAML: Convert JSON to clean, readable YAML format
Validate Only: Check if YAML is syntactically correct without converting
Clear error messages with line and column numbers

Common YAML Pitfalls

Tabs vs spaces: YAML forbids tabs for indentation — always use spaces
Colons in strings: Strings containing : must be quoted
Special values: yes, no, on, off are parsed as booleans
Anchors & aliases: Use &anchor and *alias to reuse values

Use Cases

Validating Kubernetes manifests, Helm charts, and GitHub Actions workflows
Converting API YAML responses to JSON for JavaScript processing
Debugging YAML parse errors in CI/CD pipelines
