The workspace always tells users when a file is opened locally, what transformation is being performed, and whether an export changes the original.
Table mode appears only when a real record structure exists. Invalid rows remain visible instead of disappearing.
PDF, CSV, XLSX, TXT, SQL, HTML, SVG, and PNG outputs use the correct file type — not a renamed extension.
