How to generate barcodes in bulk from Excel
Put each barcode value in Column A of your Excel or CSV file, choose the barcode type and click generate. Every row becomes a high-resolution barcode PNG image, downloaded together in a single ZIP.
Which barcode type should you use?
- Code 128 — most versatile. Encodes any text or numbers. Best for inventory, shipping labels and asset tags.
- EAN-13 — international retail standard. Required by most supermarkets worldwide. Needs a GS1-registered 12-digit number.
- UPC-A — North American retail standard (USA, Canada). 11-12 digits.
- Code 39 — older alphanumeric format, common in industrial and government settings.
- ITF-14 — for shipping cartons containing multiple retail units.
- EAN-8 — compact format for very small products like cosmetics.
Common uses
- Product labelling — generate EAN/UPC codes for every SKU from your product list. Pair with bulk QR codes for dual-label packaging.
- Inventory management — Code 128 tags for warehouse shelves and stock items.
- Library systems — unique Code 39 or Code 128 per book or item.
- Shipping — ITF-14 carton labels from your dispatch spreadsheet.
For single barcodes with full customisation, use the individual barcode generator. For product QR codes alongside barcodes, try our bulk QR code generator.
Frequently asked questions
Do I need a GS1 number for EAN-13?
To sell products in retail shops, yes — EAN-13 numbers must be registered with GS1. For internal inventory use, you can use any 12-digit number as long as it doesn't conflict with real retail codes. This tool generates the barcode image; obtaining a valid GS1 number is a separate process at gs1.org.
How many barcodes can I generate at once?
Up to 1,000 per file. Split larger lists into multiple uploads — there is no daily limit.
Is my data safe?
Yes. Barcodes are generated entirely in your browser using JavaScript — your spreadsheet data never leaves your device.
What image size should I use for printing?
Use the "Wide (3px)" bar width with a height of 100px or more for print-quality labels. Always test-scan a printed sample before running a large batch.
