Clean up YAML without reformatting it by hand
YAML is easy to read when it is consistent, but hard to scan when indentation, spacing, and key order drift over time. This formatter helps you normalize messy YAML into a cleaner version you can review and reuse more confidently.
What you can control
The tool lets you choose the formatting style that best matches your project or team:
- 2-space or 4-space indentation
- optional key sorting for predictable ordering
- line width limits or unlimited output
- immediate side-by-side size feedback
Common reasons to format YAML
Formatting is useful when you want to:
- tidy configuration files before committing them
- make long YAML documents easier to review
- normalize generated YAML before sharing it
- keep team conventions consistent across environments
Formatting can change presentation
A formatter improves readability, but options like key sorting can also change the way the document is arranged. If order matters for how people review the file, take a quick look at the result before replacing the original.
