I need to convert 15 million email contacts immediately. I have all the contacts in csv format. But my client needs it in vcard format. I've been searched all over the internet. I couldn't find a converter or script to convert csv file into vcard format.
I found a site that offering this conversion online. But it is not possible to convert all these 15 million online. So can anyone help me. Or tell me is there any product available online.
Or please give me some ideas to convert it immediately. Thanks to everyone who willing to help me. Waiting for your reply
