How It WorksYAML
Overview
This YAML formatter cleans up config files with inconsistent or hard-to-read indentation into a unified, readable style, preserving your original comments and supporting multi-document files separated by --- (common in Kubernetes manifests). Everything runs locally in your browser; your data never leaves your device.
