Need dozens of Code 128 barcodes for your products, inventory, or shipping labels? Doing that one by one can drive anyone crazy. The good news? You can generate them in bulk — right in your browser — by simply copying your data from Excel into a bulk barcode generator 128.
This guide will show youhow to use Excel data to make bulk barcodesand some handy tips to get perfect, scannable barcodes every time.
What Is a Bulk Barcode Generator and Why Code 128 Matters
A bulk barcode generator lets you create many barcodes at once — a huge time-saver for Amazon FBA, Shopify, and Etsy sellers, as well as warehouse teams that rely on barcodes for inventory tracking.
Buying official GS1 codes for every product variation can get pricey, so many businesses create internal barcodes for warehouse management, labeling, or packaging mockups.
Instead of entering codes one by one, you can manually input a dozen or more product codes into an online bulk barcode generator. Some online tools — including ours — let you copy your entire product list from Excel and generate barcodes instantly.
Code 128 is one of the most popular barcode standards used worldwide. It's compact, accurate, and can handle letters, numbers, and special characters — all in a small space. Because of that flexibility, it's the go-to format for:
• Warehouse and inventory labels
• Retail and eCommerce product labels
• Manufacturing parts and batch codes
• Shipping cartons and logistics tracking
If you need a reliable, scannable format that works everywhere, Code 128 is the safest bet.

Troubleshooting Common Barcode Generator Problems (Fix Scanning and Printing Errors)
If a barcode doesn't scan or looks blurry, it's usually a quick fix:
Problem | Likely Cause | Quick Fix |
Barcode won't scan | Wrong format | Double-check you selected “Code 128.” |
Blurry barcode | Low resolution or resizing during print | Use “Actual Size” when printing and at least 300 DPI. |
Missing barcodes | Blank lines pasted from Excel | Remove extra empty rows before copying. |
Barcode too small | Label dimensions too tight | Increase width to roughly 35–40 mm for reliable scanning. |
If in doubt, regenerate at a higher DPI or re-copy your list to remove hidden spaces.
