How it works

Complete the job in three clear steps

  1. Add source code or markup to the local workspace.
  2. Choose the relevant settings and create consistently formatted source.
  3. Review the result carefully, then copy or download it before leaving the page.

Important

Check the result before relying on it

Review generated output before using it in production. Formatters and converters can validate structure, but they cannot understand every application-specific rule or guarantee that transformed content has the intended meaning.
