Clean & Accurate YAML Beautifier

YAML is notoriously strict about whitespace and indentation. A single missing space can break your Kubernetes deployments or GitHub Actions workflows. Our client-side YAML Formatter fixes inconsistent indentation, aligns multi-document streams (---), and formats nested mappings cleanly.

  • CI/CD & DevOps Ready: Optimized for Kubernetes manifests, Docker Compose, Ansible playbooks, and GitLab/GitHub CI.
  • Multi-Document Support: Seamlessly formats YAML streams separated by ---.
  • 100% Private & Secure: Formatting happens in your browser. No infrastructure configurations or secrets ever touch a server.
  • Mobile Friendly: Switch smoothly between Input and Output tabs on mobile devices.

How to Beautify YAML

Clean and validate your YAML files in 3 steps:

  1. Paste YAML: Paste your unindented or messy YAML snippet into the editor.
  2. Beautify: Click the Beautify button to automatically normalize indentation and hierarchy.
  3. Copy or Download: Copy the formatted YAML to clipboard or save it as a .yaml file.
