Why the official conversion table matters
NACE-BEL 2025 applies from 1 January 2025 and conversions are not always one-to-one. The tool therefore reads the official FPS Economy conversion spreadsheet locally and keeps every 2025 candidate for an old code.
The current 2025 code descriptions already bundled with gratistools.be are added beside the mapped codes.
Is my data uploaded?
No. The conversion is performed in your browser, so nothing you add is sent to gratistools.be. See the privacy page for details.
