Conversion of xls files to vcf file format

In order to convert contacts from Excel XLS spreadsheet to a vCard contact file you will have to first export xls to csv and then use any of the available csv to vcf conversion utilities to get a vCard file. If you wish, you can also rename VCF to VCARD as it is the same file format, but programs usually recognize vcf suffix only.
