I receive contacts from different sources in various vCard versions. Sometimes they are v2.1, other times v3.0 or v4.0. I want a single converter that can handle all these formats without manual adjustments. Also, it should allow me to combine them into one CSV file. Is there such a tool available that works well on Windows and is easy for non-technical users?

My contacts came from many devices—some in v2.1, some in v3.0—and most converters failed. I finally found GainTools Address Book Manager, a smart vCard to CSV converter that reads all vCard formats (2.1, 3.0, 4.0) and merges them into one CSV file. It can also convert VCF to CSV in bulk without losing formatting. Compatible with Outlook, Gmail, Android, and iPhone, it runs smoothly on all Windows versions. I tried the free demo first and was surprised by its speed and accuracy. For anyone dealing with mixed contact lists, this VCF to CSV Converter is a time-saving solution that keeps data 100% safe.
