I suggest using the MacSonik CSV to vCard Converter to change your CSV files into vCard format without any data loss. This tool lets you view your files along with their data and attachments before conversion. It supports saving CSV files into different vCard versions. You can also choose where you want to save the converted VCF files on your system. Additionally, this utility provides a free demo version that allows you to convert 50 items per folder for free.
