Excel cannot open VCF contact files correctly because vCard is not a spreadsheet-supported format. When users try to open VCF files directly in Excel, the data appears disorganized or unreadable. The correct solution is to convert the VCF file into CSV format, which Excel fully supports. WholeClear VCF to CSV Converter helps users convert VCF contacts into a clean, Excel-compatible CSV file. All contact details such as names, phone numbers, email addresses, and company information are preserved and arranged properly in rows and columns, making it easy to manage contacts in Excel without errors.
