Before buying, always check two things: license scope and refund policy. Some tools limit usage to a single system or require upgrades for future versions. Others offer lifetime licenses, which matter if you convert contacts regularly. Refund terms are equally important. Look for a clear trial or demo option so you can test accuracy first. Reputable vendors, including Softaken Excel to VCF Converter, usually explain license usage and refund conditions upfront. Reading these details takes a few minutes but can save you frustration if the tool doesn’t fit your workflow.
