How do I generate barcodes from Excel?

Upload your Excel or CSV file containing barcode data. Select the column with your codes, choose your barcode type (Code 128, EAN-13, UPC, etc.), and click Download ZIP. All barcodes are generated instantly in your browser.

Does this tool preserve leading zeros in UPC codes?

Yes. Unlike Excel which strips leading zeros, our tool automatically preserves them. UPC codes starting with 0 (like 012345678905) are handled correctly without any manual formatting.

100% secure. All barcode generation happens in your browser using JavaScript. Your Excel/CSV data never leaves your device - no server uploads, no data storage, complete privacy.

What barcode formats are supported?

We support Code 128 (most versatile), EAN-13 (retail, 13 digits), UPC-A (US retail, 12 digits), Code 39 (alphanumeric), MSI (warehouse), and ITF-14 (shipping containers).

How many barcodes can I generate at once?

There is no limit. You can generate hundreds or thousands of barcodes from a single Excel file. The tool processes everything locally in your browser.
