I migrated my CSV contacts to Gmail and iPhone with the help of the GainTools CSV to vCard Converter. It will instantly convert CSV to VCF without any errors or data loss. I merely imported the vCard file which I converted in Gmail, and all my contacts were perfect. The software supports vCard versions 2.1, 3.0, and 4.0, so it supports Android, Outlook and iOS. This program is extremely easy to use even for non-technical people. Plus, you can test with the free demo first before buying it. I liked that it sorted my contact list completely. In case you need to migrate CSV to VCF for phone or email systems, this is one of the easiest ways to do it.
