When batch barcode generation pays off

Operations teams run batch generation when a new catalog lands, after a WMS migration, or before a physical inventory count. Single-item generators work for spot fixes; batch mode validates hundreds of GTINs or internal codes in one pass so you catch checksum errors before labels reach the floor.

Data preparation workflow

Export SKU or location codes from your item master with one value per row. Include optional filename and label_text columns when PNG names must match ERP document numbers. Review the validation summary — rows that fail standard rules should be corrected in source data, not patched only in the ZIP output.

Worked scenario

A spare-parts distributor receives 320 new lines from a supplier CSV. They import the file, see 12 invalid EAN-13 values flagged, fix them in the source sheet, regenerate, and download a ZIP mapped to bin locations for same-day receiving labels.

Operational FAQ

Should I use Code 128 or EAN-13 for internal bins?

Use Code 128 for alphanumeric internal location codes. Reserve EAN-13 for retail-facing SKUs that may scan at customer POS.

Can I re-run the same CSV after fixing rows?

Yes. The tool does not store uploads; upload the corrected file for a fresh ZIP.
