CSV to vCard Converter

This tool converts structured CSV contact data into the vCard format used by contact managers. It accepts a CSV input and a mapping schema that aligns CSV columns to vCard properties (NAME, EMAIL, TEL, ADR, ORG, TITLE). It validates required fields, normalizes common formats (phone numbers, emails), and outputs one or more VCARD blocks suitable for mass import. Conceptually, the tool separates data representation from storage, enabling smooth transfer between systems that export CSVs and apps that import VCARD files. Users include data teams, sales operations, and IT staff performing data portability.

Core logic and features include header inference, customizable field mapping, per-row validation, handling of multi-value fields where supported by VCARD, and generation of a single downloadable .vcf or concatenated text. Optional presets reduce setup time for common schemas (contacts, leads, or customers). The tool emphasizes data integrity: it refuses rows with missing required attributes, logs specific row-level issues, and offers a dry-run to preview results before bulk creation.

Use cases span CRM data migrations, list cleanups, and personal contact consolidation. Against raw CSV, the converter guarantees consistent VCARD formatting, UTF-8 support, and compatibility with standard contact apps. It differentiates from ad-hoc scripts by providing robust error reporting, reusable mappings, and scalable output. End users range from migration specialists to developers integrating the converter into ETL pipelines. The result is portable, standards-compliant contact data ready for downstream systems.
