🗂️Bulk QR / Barcode from CSV

Hundreds of codes from one spreadsheet

Making one QR code takes a minute. Making four hundred, one per SKU, one per order, one per shelf location, and naming every file so it can be found again takes an afternoon and ends with mistakes. Bulk QR / Barcode from CSV reads a spreadsheet export, generates a code for every row, names each file from a column of your choice and hands you a single ZIP.

How it works

1. Export your list as CSV from Excel, Google Sheets, Shopify, Amazon inventory reports or your ERP. A header row helps but is not required.
2. Drop the CSV, or switch to Paste values and paste one value per line straight from a column.
3. Map the columns: which column holds the value to encode and which column supplies the filename. Mapping SKU to both is common; mapping product URL to value and SKU to filename is how you get sku-1234.png containing a link.
4. Choose the code type: QR (with the same colour, logo and error correction options as the single generator) or a barcode symbology such as EAN-13, UPC-A, Code 128 or ITF-14.
5. Add an optional prefix or suffix. Prefixing https://yourshop.com/p/ to a column of handles turns product handles into working product-page QR codes; suffixing ?ref=box tracks scans.
6. Click Generate. A progress bar counts rows and reports invalid values, then a ZIP downloads with every PNG or SVG.

Rows are processed in a Web Worker in batches, so a few thousand codes finish in well under a minute on a normal laptop.

Why it matters

• Marketplaces and warehouses run on codes. FBA shipments want one FNSKU barcode per unit, Shopify POS scans a barcode per variant, and a WhatsApp QR code on every parcel from a Daraz order opens a support chat with the order number pre-filled.
• Filenames are the difference between usable and useless. A ZIP of 400 files named qr-001 to qr-400 forces you to open each one; files named by SKU drop straight into label software, print merges and product image folders.
• Invalid data is caught before printing. EAN-13 rows with 12 or 14 digits, or check digits that do not match, are listed in the report instead of silently producing a wrong barcode.
• Consistent styling across a catalogue looks professional. Every code in the batch gets identical size, margin and colours.

Tips

• Save the CSV as UTF-8 so non-Latin product names in the filename column survive; the tool also strips characters that are illegal in filenames.
• Use SVG output for label printers and PNG at 600 px or more for anything that will be resized.
• Keep encoded values short. A code holding a 40-character URL scans far better on a small label than one holding a 200-character one.
• Rename or convert the resulting files in bulk later with Bulk Rename + Convert, and lay them out on printable sheets with Image to PDF / PDF to Images.
• Test one value first in the QR Code Generator or Barcode Generator to settle the styling, then run the whole file here.

Privacy

Your images never leave your browser and neither does your spreadsheet. The CSV is parsed on your device, every code is rendered locally and the ZIP is built in memory, so SKU lists, customer order numbers and internal URLs are never uploaded.
