Why does CSV to VCF conversion remove empty or optional contact fields?

[tylerhoward]

From my experience, empty or optional fields usually disappear during CSV to VCF conversion because vCard apps only read fields that actually contain data. If you leave blanks, the converter skips them to keep the file clean and avoid errors while importing. I’d suggest using a converter that lets you preview and map fields properly, so you can control what stays or goes. Tools like WholeClear CSV to VCF Converter handle this smartly and keep your contacts well-structured. This advanced feature application works offline ,so there is no risk of data leak, it is completly safe. You can try this solution for free.
