Yes, and I would strongly advise that you try out a demo first before making a purchase. One of the converters I worked with a free demo for was OST to PST CSV to VCF Converter. The demo allows you to upload your CSV, get a preview, map the fields, and check the working of the CSV to VCF conversion. The only limitation is that a certain number of contacts can be exported, but otherwise, everything works normally. This way, you can ensure that the tool is able to properly convert CSV to VCF with your file. If you are concerned about compatibility or mapping accuracy, then a trial with your own CSV would be quite helpful. The demo also functions as a CSV to vCard converter, thus providing a good indication of the tool’s stability before purchasing.
