Beautify and format YAML

Paste messy or minified YAML and get it back cleanly formatted with consistent indentation, spacing, and line breaks. It's powered by Prettier's standalone build, so the result matches the formatting millions of developers already use. Big files are formatted in the background, errors show the line in a syntax-coloured editor, and you can open or drop files.

Everything runs in your browser — there's no upload, no queue, and no account. Paste, format, copy, download, or send it to Code Compare to see the changes.

YAML Beautifier — frequently asked questions

How do I beautify YAML?
Paste your YAML into the left panel and the formatted result appears on the right instantly. Copy it or download it as a file.
What does the YAML beautifier do?
It re-indents and reformats your YAML with consistent spacing and line breaks, using the same battle-tested engine (Prettier) many teams run in their editors — so the output matches a widely accepted style. Indent, line width are yours to set, and the choices are remembered.
Is my code uploaded anywhere?
No. Formatting and minifying run entirely in your browser with JavaScript — your code never leaves your device. It's free with no sign-up.
