What’s a reliable tool to convert my contact CSV file into a VCF without messing up the fields?

If​‍​‌‍​‍‌​‍​‌‍​‍‌ you are looking for something trustworthy that won’t confuse your fields, it is definitely a better idea to go with an offline tool rather than some random online converters. I had a situation where my email and phone fields were getting mixed up, but I wasn’t aware until later. The only thing that was consistently working for me was OSTtoPST CSV to VCF Converter. It allows correct field mapping, so you can manually select each CSV column that corresponds before you export. This step alone eliminates almost 90% of the errors in conversion. The program previews your file, and thus, you get to verify everything before the final CSV to VCF conversion is done. If what you want is to convert CSV to VCF in a safe manner and have a neat vCard output, then this one is a great and stable CSV to vCard converter that doesn’t corrupt ​‍​‌‍​‍‌​‍​‌‍​‍‌files.
