  2. Read the reformatted YAML in the output pane.
  3. Copy the clean result with one click.

Frequently asked questions

Does it validate my YAML?
Yes. Invalid YAML shows a parse error instead of output so you can fix it.
Is my data uploaded anywhere?
No. All parsing and formatting run locally in your browser.
