spb to vcard conversion is needed when users are looking for a way to export their contacts from Kies backups (.spb) and save them in vcard format (typically .vcf)
Using Samsung Kies desktop software it is possible to extract contacts from .spb nackups and save them in vCard format (.vcf, .vcard). Some third part programs might also achieve the same thing, but using Kies is usually better choice. Some versions of the program do not offer direct export of contacts, in which case you will have to use some older one.
