Who Is This For
When your catalog runs into hundreds of SKUs, generating barcodes one by one becomes painful and error-prone. This page and Labeliy's bulk label maker are for teams that want to upload a CSV and instantly get barcodes for an entire product list — ready to print on A4 or thermal sheets in one session.
Warehouses, marketplace sellers, and small ERP systems that already maintain SKU lists in Excel or Google Sheets get the most value from bulk barcode generation. The workflow is simple: export your product list from your current system as a CSV, upload it to Labeliy, map the barcode column to the label template, adjust the layout, and download a print-ready PDF. Every row becomes one perfectly formatted label — no copy-pasting, no manual entry, no alignment guesswork.
Bulk barcode generation is also valuable for new catalog setups. If you are onboarding hundreds of new products to your shop, marketplace, or warehouse, generating all barcodes in one session from your master spreadsheet ensures every product is labeled consistently and your spreadsheet data matches your printed labels exactly — eliminating the SKU mapping errors that inevitably happen with manual one-by-one generation.
Why You Need Barcodes
- Bulk generation ensures you never accidentally skip a SKU when creating barcodes for a new season or product batch.
- It keeps your internal codes and printed barcodes perfectly aligned with your master spreadsheet or ERP data.
- Automated generation saves hours of manual work and eliminates typos that can break scanning after labels are printed.
- Batch-generated labels are correctly aligned for your label sheet size, eliminating wasted sheets from manual trial and error.
Step by Step
- 1Prepare a CSV with at least one column containing the exact codes you want to encode (and an optional product name column for the label text).
- 2Upload the CSV to Labeliy's label maker, choose the barcode format, and map each column to the corresponding label field.
- 3Preview a few rows to ensure codes and label layout align correctly before generating the full batch.
- 4Download the PDF or ZIP of images and print directly on your label sheets or send to your print supplier.
Pro Tip
Include a short, stable SKU code in your CSV and use that as the barcode value — even if product names change, the SKU stays the same. This means you never have to reprint barcodes when you update titles or descriptions in your catalog.
