FAQ
Frequently asked questions
Short answers about file privacy, barcode formats, PDF printing, and common spreadsheet workflows.
Is BarcodeMaker free?
Yes. The current barcode label generator is free to use and does not require an account.
Are uploaded files stored?
No. Spreadsheet files are processed in your browser. BarcodeMaker does not upload or store your Excel or CSV files on a server.
Which barcode format is supported?
The current generator supports Code128, a widely used barcode format for retail, warehouses, and internal product labels.
Can I use it for thousands of rows?
Yes, but very large files depend on your browser and device memory. The PDF is automatically split into multiple A4 pages.
Why should I print at 100% scale?
The PDF is generated for real A4 dimensions. Printer scaling such as Fit to Page can shift labels and cause alignment issues.
Recommended spreadsheet columns
- Barcode value: the number or text that will be encoded into the barcode.
- Product name: the label text shown below or near the barcode.
