vCard Contact Parser & QR Generator
Parses UTF-8 vCard 3.0/4.0 contacts, folded lines, groups, quoted parameters and text escapes. Choose any contact to view its name, phones, emails, company, title, photo and profile links; all properties remain in the vCard and JSON downloads. The form creates vCard 4.0 and a new QR for its current fields.

Document parsing & data extraction pipeline
Inspects, parses, and converts open publishing and scheduling formats conforming to IDPF EPUB 3.2 / 3.3 specifications, IETF RFC 5545 (iCalendar - .ics), and RFC 6350 (vCard v4.0 - .vcf). EPUB tools unpack the OCF (Open Container Format) ZIP package, parsing META-INF/container.xml and the OPF (Open Packaging Format) package document to extract Dublin Core metadata (dc:title, dc:creator, dc:identifier), spine order, manifest items, and table of contents (NCX / Nav doc), converting chapters to Markdown.
Worked document extraction example
Scenario: Execute vCard Contact Parser & QR Generator with sample data to verify transformation accuracy and output formatting.
Sample input:
Processing: After the page loads, processing runs locally in a Worker without uploading the file. Cancel or clear stops the task.
Illustrative output:
File size & structure constraints
Input must be smaller than 5,000,000 bytes. Up to 1,000 contacts, 50,000 physical lines, 500 properties per contact and 30 seconds including reading. QR uses byte mode and error correction M, up to 2,331 UTF-8 bytes including vCard syntax. Larger cards remain downloadable without QR. Previews show 8,000 characters per field and 16,000 per source page; files are complete. Remote photo URLs are shown as text and never loaded automatically. Embedded PNG/JPEG/GIF/WebP data up to 1,000,000 URI characters can be previewed. Legacy quoted-printable, non-UTF-8 and vCard 2.1 are unsupported. This is a scoped parser, not full RFC conformance certification. Real iOS/Android camera import has not been verified. QR contains the contact itself; it is not a hosted or remotely updatable link.
vCard Contact Parser & QR Generator parses structured OpenXML and PDF data locally. Review exported tables or sheets against original files.
Zero-upload document security boundary
File buffers and document assets in vCard Contact Parser & QR Generator are processed in-memory via local browser APIs with zero file uploads to CZOA servers.
Document schemas & interchange standards
ECMA-376 Office Open XML specifications and ISO 32000 PDF reference standards:
- RFC 6350 sections 3–6 and 8; scoped v4 writer and v3/4 content-line reader, not full conformance certification
- RFC 6868 parameter escaping

Frequently asked questions
What outputs does the vCard Contact Parser & QR Generator produce?+
It extracts structured contact details—such as names, phone numbers, email addresses, job titles, and profile links—from local vCard files, and lets you download sanitized vCard 4.0 files, structured JSON records, or generate mobile-scannable QR codes.
What limits and privacy rules apply?+
Boundary constraints concerning "What limits and privacy rules apply?" prevent invalid parameter state mutations client-side.
Which formats and interoperability limits apply?+
Runtime handling of "Which formats and interoperability limits apply?" executes synchronously in your browser tab without remote delays.
