Yes, you can easily do it without Lotus Notes installed. I was in the same boat recently. TrustVare NSF Contacts Manager doesn't require Lotus Notes to run. It lets users convert NSF to VCF directly by selecting the NSF file from your system. It's a fully standalone NSF to vCard converter that reads data safely and exports it in universal vCard format. I used its NSF to VCF Converter feature to move all my contacts to my new computer in just a few minutes. It's super convenient if you don't want to reinstall Notes just for conversion.
