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.

Does this tool upload my working data?
No. The workspace processes its input in this browser and does not send the working content to Lucaden.
Should I verify the result?
