My full address book is saved in CSV format, but I need it in VCF so I can use it on different devices. Is there any quick utility to transfer CSV address book into VCF files that is reliable and user-friendly? Looking for simple steps.

Yes, you can use WholeClear CSV to VCF Converter for this task. It works as quick CSV to VCF software and helped me transfer my entire address book into VCF format easily. The tool also supports bulk CSV to VCF conversion, so you don’t have to convert files one by one. It keeps all details like phone numbers, emails and names intact during the process. For me it worked like a reliable CSV to vCard converter on Windows and it supports all vCard versions too.
