You can easily convert CSV to VCF on Windows in 2026 without losing any data. First, ensure your CSV file is clean and saved in proper encoding and structure. Then, check all important fields like name, phone, email, and address are correct or not. After that, you can use manual methods to transfer spreadsheet-based/comma-separated value contacts into an Android-supported vCard format. But the problem is that the manual method works only with small or one contact at a time, which makes it time-consuming for large contact lists. The best option is using a reliable offline converter solution for fast and secure contact management, like WholeClear CSV to VCF Converter. This Windows software allows bulk conversion while preserving all contact details, supports field mapping, and handles special characters accurately, ensuring no data loss during the process. You can effortlessly try this bulk CSV to VCF Conversion.
