Data Importer & Cleaner v1.0.1

This audit-hardening release aligns the downloadable Windows application with the current documented and tested product state.

Fixed

• made the selected data culture deterministic across import, profiling, validation and cleaning;
• applied a saved profile's culture before parsing source values;
• exposed profile and culture selection before file import;
• limited the interactive preview to 1,000 rows without limiting validation, cleaning, deduplication or export.

Quality
