You can print the information from a vCard (mainly .vcf) file to a PDF file using the Print function and saving it to a file instead of printing it on paper. That however requires a PDF printer installed. This is only good if you need the text data and won't use them to import your contacts to a personal contact management program.

The table with program actions contains information about what each program is capable of doing with their files. This may be a good pointer for further searches for certain file conversions and help you find the converter you are looking for if our search result is insufficient for you. However, it is far from perfect and may sometimes show results which are not really usable because of the nature of the software handles the files. So a conversion that appears as possible, just because of matched actions, may in fact not be possible.
