How to Fix CSV to vCard Conversion Errors in Windows

There are many users who want to import contacts from a CSV file to vCard (VCF) format so they can import them to Android phones, iPhones, Microsoft Outlook, Apple Contacts, Gmail, and other contact management applications. The process sounds simple but many Windows users are experiencing frustrating conversion errors. Contacts may not be converted, phone numbers may be lost, email addresses may not be transferred correctly, or the resulting VCF file may fail to open altogether.
