How can I convert very large Excel contact files safely to VCF?

I am currently dealing with a very large Excel file that contains thousands of contact records, including names, phone numbers, email addresses, and other details. I need to convert this Excel contact file into VCF (vCard) format so that I can import it into my mobile phone and email applications. The main challenge is that the Excel file is extremely large, and when I try online converters or basic tools, they either crash, skip contacts, or cause data corruption. I am also concerned about data privacy and security, as these contacts are important and confidential. I am looking for a safe, reliable, and efficient method to convert large Excel contact files into VCF format without losing any data or compromising security. What is the best approach or tool to handle this situation?

When an Excel file has thousands of contacts to convert to another format, it can be risky. Because an online and manual tool can not handle a large Excel file simply.
