What is a bulk barcode generator?

A bulk barcode generator is an automated tool that renders hundreds of linear barcodes simultaneously from a list of product codes or spreadsheet rows.

How do I generate barcodes in bulk from an Excel or CSV file?

Export your spreadsheet column as a CSV file or paste the list of numbers, select your barcode symbology, and click 'Generate All Barcodes'.

Which barcode formats are supported in bulk mode?

Our bulk generator supports Code 128 (alphanumeric), EAN-13 (global retail), UPC-A (US retail), and Code 39 (industrial/logistics).

How does the tool calculate check digits in batch mode?

The engine automatically calculates and validates Modulo-10 check digits for UPC and EAN codes to prevent invalid retail scans.

Can I customize the dimensions and bar height of all barcodes?

Yes. Bar width, bar height, font sizes, and margin quiet zones can be configured universally across all generated barcodes.

Is there a limit on how many barcodes I can batch generate?

You can generate hundreds of barcodes in a single session smoothly directly in your browser without throttling.

How do I import the downloaded barcodes into label printing software?

Unzip the downloaded archive and import the PNG or SVG files into label printing software (such as Avery, Zebra, or Photoshop).

Are my product SKUs or barcodes sent to any external server?

No. All barcode generation and ZIP packaging execute locally in your web browser with 100% privacy.
