If you need to import contacts into a CRM, in my opinion, the best option is converting VCF to CSV, because most CRM software supports the importation of CSV files, which makes it easy to map fields such as name, email, phone number, and company. You can also try to import the VCF file into Outlook and then export it to a CSV file.

In my personal experience, using a Windows offline VCF to CSV migration tool is the easiest and best choice, because a third-party tool ensures that there is no risk of data loss or data leak. There are many applications available, such as a dedicated Softaken vCard to CSV Converter. With this utility, you simply add the VCF file, choose CSV as the output, and export. The software is compatible with all Windows OS and ensures proper organization of contact information, which helps in smooth CRM field mapping.
After contact migration, you can easily open your CSV file in Excel, review the columns, and then upload it into your CRM system.
