Who Uses Bulk Barcode Generation from CSV?
Frequently Asked Questions
What CSV format does this generator accept?
One barcode value per row. The first column is used as the barcode content — all other columns are ignored. A header row is optional: if the first row looks like a header (contains letters), it is skipped automatically. Export from Excel or Google Sheets using File → Download → CSV, or just paste a plain list.
How many barcodes can I generate at once?
Up to 500 barcodes per generation, free, with no signup. For larger batches, split your CSV into multiple files and run in batches.
What barcode formats are supported?
CODE128, EAN-13 (with auto check digit), UPC-A, EAN-8, ITF-14 and CODE39. All formats generate print-quality PNG images at 2× resolution.
Does EAN-13 check digit get calculated automatically?
Yes. If you enter 12 digits, the 13th check digit is calculated and added automatically. If you enter a 13-digit EAN with an incorrect check digit, it is corrected automatically.
Can I download all barcodes at once?
Yes. "Download all PNG" downloads a ZIP file containing individual PNG images named by barcode value. "PDF sheet" generates a multi-page A4 PDF with barcodes arranged in a grid for label printing.
Is this free? No watermark?
100% free. No signup, no watermark, no download limit. Barcode images are clean and print-ready.
