If your Excel contacts won’t open after converting to a VCF file, the issue is usually with the file format. Many Android phones can’t read VCF files made by unreliable converters. The Softaken Excel to vCard Converter creates properly formatted VCF files that open easily on Samsung, Vivo, Oppo, and other Android phones. It holds all names, phone numbers, and emails exactly where they should be. You just copy-paste the file to your phone and then import the vcf file from the Contacts app. Everything loads correctly without missing or blank entries.
