Field notes
The workflow keeps source files on the user’s machine and treats transformations as reversible history points rather than destructive edits. Its redaction system uses format checks such as Luhn, mod-97, and Verhoeff validation, then carries masked values into exports. The page also says cleanup recipes can be replayed over a later file or folder, connecting one-off spreadsheet work to repeatable operations.
