Bulk QR Code Generator
Generate up to 200 high-resolution QR codes in seconds from an Excel (.xlsx) or CSV file. Map spreadsheet columns to QR fields, preview rows, and download a complete ZIP package.
Upload Your Spreadsheet
Upload CSV or Excel (.xlsx) files with up to 200 rows. All file data is processed locally in your browser and never leaves your computer.
Bulk Generation Guide & Performance Best Practices
Your spreadsheet is parsed locally on your computer using client-side SheetJS. No sensitive customer lists or inventory spreadsheets are uploaded to remote cloud servers.
To preserve browser responsiveness and prevent memory crashes, batches are capped at 200 rows per session. For larger lists, simply upload in chunks.
All generated PNG codes are compressed into a clean .zip folder using JSZip with file names matching your spreadsheet labels for fast sorting.
