Paste messy YAML and get a clean, readable version in seconds, right in your browser.
Your code never leaves your browser. Everything runs locally on your device.
YAML copied from generated configs is often cramped into flow style or tangled with uneven indentation. The YAML Beautifier rewrites your YAML in clean block style with consistent indentation, so every nested map and list is easy to read and edit.
Everything runs in your browser, so your files are never uploaded to a server. Paste your YAML, beautify it, and copy the result straight into your project.

No. All beautifying happens in your browser on your own device, so your files never leave your computer.
The tool shows a clear error message and keeps your input untouched, so you can fix the problem and try again.
If your YAML is already tidy, try the YAML Minifier to shrink it into compact flow style.
