Yes, bulk conversion is possible without doing everything manually. I recently needed to export hundreds of contacts from an Excel sheet into a VCF file for Android import. Instead of using online tools that often mess up formatting, I used WholeClear Excel to VCF Converter. It allows bulk export of contacts from Excel into one VCF file in just a few steps. You simply load the Excel file, map fields, and convert. It handles large Excel files without slowing down and keeps all contact information intact. The interface is very simple, so even if you're not technical, you can complete the process quickly. For bulk Excel to vCard conversion with accurate results, this method works well.
