I am currently managing a large contact list stored in an Excel spreadsheet and need to convert it into VCF (vCard) format so that I can import the contacts into my mobile phone and email applications. While searching online, I found many Excel to VCF converter tools, but I am concerned about data security, malware, and reliability, especially when downloading software on a Windows system. Can anyone recommend a trusted and safe Excel to VCF Converter for Windows? It would be helpful if the solution supports bulk conversion, preserves all contact fields (name, phone number, email, and address), and works smoothly on Windows without data loss.
