CSV to Barcode Generator
Generate many barcodes at once from a column of CSV data, then download them together. It turns a spreadsheet of codes into ready-to-use barcode images in bulk.
Bulk barcodes from a spreadsheet
Making one barcode is easy; making hundreds by hand is not. If you have a CSV list of product codes, SKUs, or IDs, this tool reads the column and produces a barcode for each, so you can label an entire inventory in one pass instead of generating them one at a time.
The data you encode must match the barcode type's rules - some formats accept only digits, some a fixed length - so clean, consistent input is what makes a batch scan reliably.
Getting a reliable batch
Prepare the CSV so every code is valid.
- Make sure each value fits the barcode format's character and length rules.
- Remove stray spaces, which can be encoded and cause scan failures.
- Test-print a few before producing the whole set.

FAQs
What barcode formats are supported?▼
Common formats are supported, but each has rules - some accept only numbers, some require a fixed length or a check digit. Match your data to the format you choose.
Is my CSV uploaded?▼
No. The barcodes are generated in your browser, so your product or inventory data stays on your device.
Why does a barcode fail to scan?▼
Usually because the data did not fit the format (wrong length or invalid characters), the print is too small or low-contrast, or a stray space was encoded. Validate the input and print clearly.
How many barcodes can I generate at once?▼
It is built for bulk generation from a CSV column, so you can produce a large batch in one go.
What column should my codes be in?▼
Put the values to encode in a clear column, ideally with a header. Clean, one-code-per-row data produces the most reliable batch.
Should I leave quiet space around each barcode?▼
Yes. Barcodes need a clear margin (quiet zone) on the sides to scan. Cropping too tight is a common cause of failures.
What size should I print them?▼
Large enough that the narrowest bars stay crisp. Test-scan a printed sample at your intended size before committing to a full run.
Is a barcode the same as a QR code?▼
No. Traditional barcodes are one-dimensional and hold less data, typically a code or number. QR codes are two-dimensional and hold more, like URLs. Use the QR Code Generator for those.
