The best way to convert Excel data to vCard format is to use a professional converter tool. Let me recommend the Cigati's Excel to vCard Converter Tool that offers advanced features to make the conversion fast and effective. The software has an interactive user interface so that anyone with or without technical expertise can use the software. Also, the software is compatible with all versions of Windows. It also supports multiple Excel files, like spreadsheet documents (.xlsx, .xls, .xlsm, .xlsb, .xltx, .xltm, .xlt, .xlam, .xla).
