Ran the CSV through our deduper first. Encoded UTF-8 with no character-set surprises in Excel. Bought it while building a radiologist doctor prospecting workflow for Austria. Decent value, would tighten one or two fields.
Good to know what worked and what didn't, we hear you on the gaps — the next monthly refresh tightens those exact columns. If you want the gaps fixed sooner than the next refresh, open a support ticket and we'll spin a one-off pull.
