I had multiple CSV contact files and wanted a single VCF. I used
GainTools CSV to vCard Converter, which handled all files smoothly. It also did a great job in assigning names, emails, and phone numbers to the right fields without making any mistakes. The
CSV to VCF converter was fast, and all contacts remained intact. Even very large files were processed in a short time, and the final VCF could be used on Android, iPhone, and Outlook. This tool was a real time-saver for me it took less than an hour compared to the manual merging process. It’s very easy to use, trustworthy, and great for merging various contact lists quickly and effortlessly.
