To split individual contacts from a single vCard file, I recommend WholeClear Split vCard Software. This tool is designed to split a multi-contact VCF file into separate .vcf files, one for each separate contact, without any data loss and preserves all contact details including name, number, email and address fields. The software can split vCard files exported from Android, iPhones, Gmail, Outlook and many others. It operates quickly, accurately, and is very intuitive, even for the non-technical user. I have used it in the past for bulk contact management, and it works perfectly.
