Heres something practical: dont trust browser-based converters with your contact data. The TrustVare CSV to vCard Converter is a Windows-only offline tool that gives you control and supports all vCard formats. That means whether you need vCard 2.1 for older systems or 4.0 for modern apps, youre covered. Before you commit, you can try the free demo to see how it handles your CSV and if the field mapping matches what you expect. It handles large lists without breaking, preserves formatting, and keeps every phone and email intact. For anyone who cares about data quality and privacy, this is a solid pick.
