I have a large list of contacts stored in an XLS file, and I want to convert them into VCF (vCard) format so that I can import them into my phone and email applications. However, most of the solutions I found online require uploading the file to a web-based converter. Because my contact list contains sensitive personal information, I’m concerned about data privacy and would prefer not to upload it to any online service. I’m specifically looking for a method or tool that can convert XLS contacts to VCF completely offline on my computer without sending data over the internet. Has anyone here done this before? What is the safest offline way to convert XLS contacts to VCF while keeping all the fields like name, phone number, email, and address intact?
