Can CSV to VCF conversion be done without installing Outlook?

Yes, it is possible only with a third-party tool like Softaken CSV to VCF Converter. Why is this tool the best for converting spreadsheet or CSV contacts into VCF? Because this is an offline utility that works on all Windows operating systems without any compatibility issues. It also supports all vCard versions, so you can easily convert your CSV contacts into any VCF (vCard 4.0, 3.0 and 2.1). The best part is that there is no requirement for any Outlook installation. I also used this solution for CSV to VCF conversion; it works independently and provides an accurate result while maintaining data integrity and keeping it secure. It supports field mapping and bulk CSV contact migration. You can also try this solution by downloading the tool.
