What is YAML Formatter & Beautifier?
Paste YAML and get it reformatted with clean, consistent indentation instantly — useful for cleaning up a hand-edited config file or normalizing YAML from different sources. YAML is whitespace-sensitive, so inconsistent indentation from copy-pasting between files (like a Docker Compose file or a CI pipeline config) is a common source of confusing parse errors. Formatting runs entirely in your browser as you type, and the tool surfaces the parser's real error message if the YAML isn't valid to begin with.
