How to open, merge, and convert VCF contacts
Choose one or many VCF files. Siftlet unfolds vCard records, decodes common quoted-printable names, and builds a searchable address book without uploading it.
Duplicate groups are deliberately conservative: two records must share the same normalized email address or a phone number with at least 7 digits. Names alone never trigger an automatic merge. Keep your original VCF as a backup before importing the cleaned copy.
Generic CSV works well in spreadsheets and CRMs. Google Contacts CSV uses Google's familiar column names. VCF is best for importing back into iPhone, Android, Outlook, or another contact app. Mobile browsers can offer the system share sheet for every export.
