Bulk barcode generator
The bulk generator reads a list of numbers from a spreadsheet and draws one barcode for each, checking every number first and offering a fix for a wrong check digit. It is free and runs in your browser, so your list stays on your computer. The free plan exports the first 50 rows.

How to do it
- Open Bulk and drop in an Excel (.xlsx) or CSV file, or paste rows copied from a sheet.
- Match the column that holds the numbers. A column named like gtin, ean, upc, barcode, sku or code is picked up by itself.
- Choose Barcodes and then the barcode type, such as EAN-13 or Code 128.
- Fix flagged rows, or use Fix all check digits, then download a ZIP of PNG or SVG files.
What it checks
Every row is checked against the barcode type you chose. A row with an empty number is flagged as required. A number the type cannot draw is flagged with a plain-words reason. For EAN-13, EAN-8, UPC-A and ITF-14, a number of full length with a wrong check digit is flagged with the digit it should end in, and the fix is one click.
Worked example with EAN-13: a row holds 2012345678917. The check digit works out to 0, so the row says the last digit should be 0 and offers Use 2012345678910. Fix all check digits does this for every row at once. EAN-13 also accepts 12 digits and draws the check digit for you.
Files you get
The ZIP holds one file per row, named with the row number and the title, plus an index.csv listing the row, the file name and the number. Barcodes are drawn as PNG at 300 DPI, or as SVG. The free plan exports the first 50 rows, and up to 5000 rows are read from a file. Old .xls files are not read.
The barcode type list leaves out postal, banking and stacked symbols, which suit other tools.
Numbers are yours to supply
This tool draws numbers you give it and does not issue official product numbers. Numbers for goods sold in shops come from GS1 membership. Numbers starting with 2 are meant for use inside one shop only, which makes them fine for your own shelf and stock labels.
Questions
Which barcode types can I choose?
The list covers the common retail, logistics and industrial types, such as EAN-13, UPC-A, Code 128 and ITF-14. Postal, banking and stacked symbols are left out of the bulk list.
Can I get printed labels instead of loose files?
Yes. Choose Labels in Bulk, or use the label maker, to put barcodes with names and prices on A4 sticker sheets or thermal rolls.
How do I know the barcodes scan?
Each barcode is checked against its number before export, and the single-code generator reads a drawn code back. Print one sample and scan it before a long run.
Is my list uploaded?
No. The file is read in your browser and the images are made there.
