📋 YAML Formatter & Validator

YAML Formatter & Validator — Online Tool

YAML (YAML Ain't Markup Language) is a human-readable data serialization format used widely in configuration files for Docker, Kubernetes, GitHub Actions, Ansible, and many other tools. Our YAML validator checks for common syntax errors like missing spaces after colons, tab character usage (YAML requires spaces), and incorrect indentation. Paste your YAML and get instant feedback.

YAML vs JSON vs XML

YAML is a superset of JSON, meaning valid JSON is also valid YAML. YAML is preferred for configuration files because it is more readable and supports comments (unlike JSON). JSON is preferred for APIs and data interchange. XML is used in enterprise systems and document formats. Each has its strengths — use YAML for configs, JSON for APIs, and XML for document-centric data.
