Bulk QR code generation from CSV data is useful for inventory management, event ticketing, product labeling, and marketing campaigns. This tool reads a CSV file and generates a unique QR code PNG image for each row, with configurable column selection for the data to encode. You can specify which column contains the strings to encode, or leave the selection blank to encode the full row as a single QR code. The tool renders QR codes using the qrcode library with error correction level M (15% recovery), ensuring scannability even if the code is partially damaged or obscured. Each QR code is displayed on screen in a scrollable gallery, and you can download individual codes or batch-download all codes as a ZIP archive. All rendering happens in your browser using Canvas API, with no server round-trips. The tool handles CSV files with thousands of rows, generating codes in a Web Worker to keep the interface responsive.
