Bulk QR Code Generator – Generate QR Codes from CSV | ZechKit

Generating batch QR codes for enterprise ticketing or warehouse asset tracking requires high-performance memory management. ZechKit processes imported spreadsheets entirely client-side using chunked rendering loops and HTML5 canvas instances to prevent UI freezes:

• RFC 4180 CSV Parser: Automatically detects commas, tabs, and semicolons, parsing quoted cells, multiline notes, and UTF-8 BOM headers.
• Column Selector & Variable Interpolation: Encode a single column (e.g. Ticket_ID) or combine multiple columns into structured URL endpoints using template variables like https://events.com/checkin/{{Ticket_ID}}.
• Duplicate & Anomaly Detection: Automatically scans your dataset for empty cells or duplicate values, allowing you to filter out duplicate rows or proceed with batch generation.

In addition to exporting standalone QR images, ZechKit can format your batch as printable label sheets:

• Visible Metadata Text: Print column headers (e.g. Attendee_Name, Device_Model, SKU) alongside each QR code.
• Grid Sheet Layouts: Supports $1 \times 1$, $2 \times 2$, $2 \times 3$ (6 per page), $2 \times 4$ (8 per page), $3 \times 4$ (12 per page), and $4 \times 6$ (24 per page) grids.
• Multi-Page Vector PDF Export: Generates resolution-independent vector PDF documents using pdf-lib formatted for ISO A4 and US Letter paper.

Download all generated QR codes bundled into a single compressed .zip file using jszip. You can customize file naming using column variables (e.g. ticket-{{Ticket_ID}}.png or asset-{{Asset_ID}}.svg) to ensure files match your database naming conventions.
