I recently tried to import my contacts from an Excel file (XLS/XLSX) into my email client, but I noticed that these formats are not directly supported. I have seen CSV or vCard (VCF) formats being recommended instead. Can someone explain why XLS and XLSX are not considered standard contact formats for email clients? Also, what is the best way to convert or import Excel contact lists so that they work smoothly with Gmail, Outlook, or other email services? I am looking for reliable methods or tools that can handle large contact lists without losing data.

The purpose of an Excel file (XLS or XLSX) is to store data in a structured manner using tables therefore, it typically will not include contact information, which makes it unreadable by email or phone contact applications. Rather, the type of file that these applications can access is known as VCF or (vCard). VCF files are created to store names, phone numbers, email addresses and other contact details in a way that apps can understand. If you try to import Excel contacts directly, some information can be lost or seem incorrect. So the simple solution is to use ToolsBaer Excel to vCard Converter. This tool converts your Excel XLS or XLSX file into a VCF file. After conversion, you can easily import it into Gmail, Android phones, iPhones, or any other contact app. This keeps all your contact information safe and organized without any duplicate files.
