YAML Formatter
Format and beautify YAML data with proper indentation and validation.
Formatting and Cleaning Up YAML Files
YAML is a human-friendly configuration format commonly used in tools like Docker, Kubernetes, CI/CD pipelines, and application settings. While it’s easy to read, YAML is also very sensitive to indentation, which makes small spacing mistakes a common source of errors.
This formatter helps normalize YAML layout by cleaning up spacing around keys, fixing inline collections, and applying consistent indentation. The goal is clarity and structure—your data stays the same, but it becomes easier to review and troubleshoot.
How do I validate YAML?+
Paste your YAML and format it; syntax errors are reported.
Are my files uploaded anywhere?+
No. Formatting happens entirely in your browser. Nothing is sent to a server, so your data stays on your device.
Is it free?+
Yes. No signup, no limits, no watermarks.
