Of course, you can convert saved CSV contacts from Yahoo Mail into a VCF (vCard) format compatible for iOS 17.
While iPhones—including those running iOS 17—import contacts using the VCF format Yahoo Mail allows you export your contacts as a CSV file. You have to first convert the CSV file into a VCF file before shifting your Yahoo contacts to your iPhone.
If you try to do this manually, particularly if you have many contacts or are not familiar with contact formats, this procedure can be a bit difficult. When you import any information—name, phone number, email, etc.—you would want to make sure all the contact fields match properly. Some information might not show up appropriately.
To make things easier, there are tools that can do this conversion for you in just a few clicks. These applications automatically generate a VCF file from your CSV file that you may effortlessly upload into your iPhone. One example of an advantageous tool is the
