How to make barcodes in bulk
- Add your values. Paste them one per line, click Open CSV or text file, or use Make a number sequence for runs like INV-00001 to INV-00500.
- Pick the column if your file has several. We list the headers and suggest the one that looks like SKUs or barcodes.
- Choose the barcode type and size. Every barcode in the batch uses the same settings. Lines that aren't valid for the chosen type are listed with the reason, and the rest still work.
- Download the ZIP, or press Print on label sheets to send the whole list to the label maker.
From Excel or Google Sheets
Save your sheet as CSV (File → Save As → CSV in Excel, File → Download → CSV in Google Sheets) and open it here. Or just copy the column in your spreadsheet and paste it into the box. Each cell becomes one line.
Files are read in your browser, not uploaded. That makes the tool fast, and your product list stays private.
File names
Each file is named after its barcode type and value, such as code-128-SKU-01001.png, so you can match images to products. Characters that aren't allowed in file names are replaced with dashes, and duplicates get -2, -3 and so on.
Limits
- Up to 5,000 values per batch. Larger lists work, but split them so your browser stays responsive.
- The preview shows the first 60. Every valid value goes into the ZIP.
- Need the check digit added to a list of UPCs? Use the UPC-A type and enter 11-digit numbers; each gets its own check digit.
