YAML Formatter
YAML prettify, minify, and validate—with clear error messages.
Output
Output will appear here.
How to use
Paste your YAML document. Prettify normalizes indentation for maps and sequences; Minify removes extra blank lines and trims indentation noise.
Validate surfaces parse errors with a readable message—try a smaller excerpt first when debugging a huge file.
Split very large payloads or paste only the fragment you need to keep the tab responsive. Copy output straight into your editor or pipeline YAML.
Keyboard: Tab / Shift+Tab to indent lines; Ctrl/Cmd+D duplicates the line below.
