Barcode List Cleaner

Paste a list, one item per line, and tidy it in a few clicks: remove duplicates and empty lines, trim spaces, keep digits only, change the case, pad with zeros, add a prefix or suffix and sort. The result updates as you type, and it stays in your browser.

When the list is ready, send it to the Code 128 or QR code generator, or load a file in Print Label / PDF.
