CSV Barcode Generator — Upload Spreadsheet, Download All Barcodes
The BatchPrintGTIN CSV barcode generator processes entire spreadsheets to produce barcode images for every row simultaneously. Upload a CSV file, select your barcode format, configure display options, and download all barcodes as a ZIP archive of individual PNG files or a single multi-page PDF. Generate hundreds of barcodes in the time it would take to manually create ten.
How to Use the CSV Barcode Generator
The process takes four steps. First, prepare your CSV file — a standard comma-separated values file with one barcode per row. The minimum requirement is a column containing the barcode value (the number or code to encode). Optionally include a column for the label text to display beneath the barcode. Second, open BatchPrintGTIN and click the Batch Generator tab. Third, upload your CSV and map the columns — select which column contains the barcode value and which contains the label text. Fourth, choose your barcode format (UPC, EAN-13, Code 128, QR, etc.), set display options, and click Generate. Download the full batch as ZIP or PDF.
CSV File Format
The CSV file can be created in Microsoft Excel, Google Sheets, Apple Numbers, or any spreadsheet application. Export as .csv (comma separated values). A minimal CSV looks like this:
barcode,label
012345678905,Product A
012345678912,Product B
012345678929,Product C
The header row is optional — if your file has no header, the generator uses the first column as barcode values by default. Additional columns (price, description, SKU) are ignored unless mapped. Column order does not matter — you select which column maps to which field during the upload process.
Quick access: UPC-A · EAN-13 · Code 128 · FNSKU · ITF-14 · PDF417
Supported Barcode Formats for Batch Generation
The CSV generator supports all the same formats as the single barcode generator:
- UPC-A, EAN-13, EAN-8 — retail product barcodes
- Code 128, Code 39 — alphanumeric inventory and shipping codes
- ITF-14 — carton and case barcodes
- QR Code — URLs, text, WiFi, contact cards
- Data Matrix, PDF417 — industrial and high-density applications
All rows in a single CSV must use the same barcode format. To generate a mix of UPC and QR codes, process them in separate batches.
Download Options
ZIP archive — downloads a ZIP file containing one PNG image per barcode, named by the barcode value or label text. Suitable for importing into packaging design software, product listing tools, or asset management systems.
PDF export — generates a multi-page PDF with barcodes arranged in a grid. Use the Page Designer layout options to specify label sheet format (Avery 5160, A4, etc.) for direct printing. The PDF is vector quality, suitable for professional print production.
Excel export — exports a spreadsheet with barcode images embedded in cells alongside the source data. Useful for inventory documentation and record-keeping.
Common Use Cases
- E-commerce product catalogue — generate UPC or EAN barcodes for an entire product range from an exported product list
- Amazon FBA batch labelling — generate FNSKU Code 128 labels for a full shipment from an exported inventory list
- Retail price labelling — generate shelf labels with UPC barcode and price for a seasonal promotion
- QR code campaigns — generate unique QR codes for every store location or campaign variant from a URL list
- Asset tracking — generate Code 128 asset tag barcodes for every item in an equipment register
- Event ticketing — generate unique QR or Code 128 ticket codes for each registered attendee
Frequently Asked Questions
How many barcodes can I generate in one batch?
BatchPrintGTIN processes the entire CSV in your browser with no server-side limit. Practical limits depend on your device — most modern laptops and desktops handle 1,000–5,000 rows without issue. For very large batches (10,000+), process in chunks of 2,000–3,000 rows.
Can I use Excel (.xlsx) files instead of CSV?
The batch generator also accepts Excel files directly via the Excel upload option, in addition to CSV. The column mapping process is identical.
Are check digits calculated automatically for numeric barcodes?
Yes. For UPC-A, EAN-13, EAN-8, and ITF-14, the check digit is calculated and appended automatically if you provide the data digits without the check digit. You can also include the full number with check digit and the generator will validate it.
