Aryson CSV to vCard Converter can merge all your contacts into a single VCF file. This tool allows you to import either a single CSV file or an entire folder containing multiple CSV files. During the conversion process, you can choose to export all contacts into one unified vCard file. It also offers features like auto and manual mapping of CSV columns to vCard fields, supports multiple vCard versions (2.1, 3.0, and 4.0), and is compatible with various CSV formats from applications like Excel, Google Sheets, and OpenOffice Calc. Additionally, you can preview your contacts before conversion and select the desired saving path for the resultant vCard file.
