CSV files are plain text files that can be edited using any text editor. VCF files store information regarding your contacts, enclosing vCards (Virtual Business Cards). Such files are used to export and import contacts from and to mobile phones (Android or iPhone), Microsoft Outlook, iCloud, Gmail, etc.
Designed with simplicity in mind, “CSV to VCF Converter” can only perform one task: that of extracting the contacts from the input CSV container, then transfer it to a newly created VCF file. In other words, you just have to select the input Excel file and choose to export it to VCF format, all with just a few clicks.
All this conversion is done completely offline. You are the only controller of your private data.
No contact information is sent to internet in any case.
