vCard (.vcf) Contact Parser & QR Generator
vCard (.vcf) Contact Parser & QR Generator: Parses vCard 3.0/4.0 properties, formats normalized contact fields, and compiles a mobile-scannable QR code.
About this vcard (.vcf) contact parser & qr generator
vCard (.vcf) Contact Parser & QR Generator — browser-based utility.
How this tool works
Implements client-side vCard (.vcf) Contact Parser & QR Generator operations. Parses vCard 3.0/4.0 properties, formats normalized contact fields, and compiles a mobile-scannable QR code specifically designed for a sales professional parses a `.vcf` electronic business card and creates a scannable contact qr code.
- Container Unpacking & XML Navigation: Unpacks the EPUB/iCalendar file stream, parsing root XML structures and calendar VEVENT blocks.
- Metadata & Spine Extraction: Extracts Dublin Core book metadata, manifest items, and spine reading order, or parses recurrence rules (RRULE).
- Content Transformation: Strips HTML formatting from XHTML book chapters to produce clean Markdown, or maps vCard contact fields to QR codes.
- Diagnostic Reporting: Reports broken manifest links, missing spine references, and calendar timezone offsets.
Worked example
Scenario: Read two complete vCards and make a QR for the first.
Sample input:
Processing: Regex-count complete cards, collect plain FN lines, then QR-encode first card.
Illustrative output:
Limits and verification
DRM-encrypted EPUB books (protected by Adobe Adept or FairPlay) must have encryption removed before inspecting contents. iCalendar parser supports standard recurrence rules (RRULE); complex EXDATE exclusions are noted.
Examples demonstrate an expected workflow; they do not prove every input or every branch of an external specification. Check important results with an independent source before using them for money, security, compliance, safety, or irreversible file changes.
Browser processing boundary
Tool input is processed by code running in the browser and is not intentionally sent to a CZOA processing API. The page can still request ordinary site assets, analytics, or advertising when those services are enabled. Browser extensions and managed-device software remain outside this tool's control.

Frequently asked questions
How does vCard Parser count cards and names?+
It regex-matches complete BEGIN:VCARD through END:VCARD blocks case-insensitively and collects trimmed values only from plain line-start FN:. JSON reports cards, names, and QR status; it does not normalize contact fields or parse vCard properties.
Which controls and result are present?+
The page offers a local .vcf chooser and Process locally. It displays cards, names, QR status and a 320-pixel QR image with margin 2. There is no contact editor, property picker, version switch, QR size option, save-contact action, validation mode, or multi-card QR selector.
What limits apply to this vCard and QR path?+
It does not unfold folded lines, parse FN parameters, decode escapes, validate versions or fields, merge contacts, or repair invalid cards. The QR encodes the first complete card, or all input when none exists; it does not prove that arbitrary text can be imported as a contact.
What did isolated browser verification establish?+
A local browser run read independent CRLF input with two complete cards, two plain FN lines and one parameterized FN. It returned cards 2 and exactly Ada Lovelace and Grace Hopper, showed a QR for the first card, and recorded no fixture payload request.
