About this tool
Format and validate YAML configuration files with proper indentation. YAML is indentation-sensitive, making proper formatting critical for correctness. The formatter normalizes indentation, validates syntax, and shows errors with line numbers. Use it for Docker Compose files, Kubernetes manifests, GitHub Actions workflows, Ansible playbooks, and any YAML configuration.
