How to Generate Bulk Barcodes from a CSV
Turn a spreadsheet column of SKUs or serials into a ZIP of barcode images. Prepare the CSV, pick a symbology, then print or archive the files.
One value per row is the easy path
Bulk barcode tools expect a table: headers in row 1, then one barcode payload per data row. SKUs, invoice numbers, and serials work well. Paste or upload that CSV into the Bulk Barcode Generator.

TSH-101,Navy tee
TSH-102,White tee
TSH-103,Black teeMatch the symbology to the data
Code 128 is a practical default for mixed letters and digits. EAN-13 and UPC-A expect a specific digit length and checksum. If a row is the wrong length, skip or fix that row instead of forcing an invalid barcode.
For a single value, use the Barcode Generator. For URLs and Wi-Fi payloads, use a QR Code instead of a 1D barcode.
From JSON APIs to CSV first
If your catalog is a JSON array of objects, convert it with the JSON to CSV Converter, then feed the CSV into bulk barcodes. Nested fields flatten to dotted column names.
Print and file-size notes
Download a ZIP of PNG (or SVG where offered) rather than screenshotting the page. Quiet zones around the bars matter for scanners. Very large batches can be heavy in a browser; split the CSV if the tab slows down.
