I encountered into the same issue when I tried to move contacts from a CSV file to my phone, which only works with the vCard (.vcf) format. After trying a few methods, I found that converting CSV to vCard manually can be really confusing, especially with all the mapping of fields and formatting issues.
Softaken CSV to VCF Converter was the best tool I could find for this task. It generates vCard file quickly that works ideal with phones and email apps after you load your CSV file and check your contact information. This was the most hassle-free way for me to convert CSV to vCard format without any errors. I definitely recommend giving it a try if you want a quick and reliable way to
export contacts from CSV to vCard format for better compatibility and easy sharing.
