Bulk barcode questions
Does this check EAN-13 and UPC-A check digits?
Yes. Every EAN-13 and UPC-A value is checked before it can be included in the download. Values with the wrong length, non-numeric characters, or an invalid final check digit are identified by row.
What happens to invalid rows?
The validation summary gives the original CSV row number and reason. Invalid rows are not added to the downloaded ZIP, while other valid rows continue to be processed.
Are my barcode values uploaded?
No. CSV parsing, checksum validation, PNG rendering, and ZIP creation run locally in your browser.
