Barcodeworks is a freeware plugin for Microsoft Word (97 and above). It can be used to insert UPC, EAN-8, EAN-13, JAN codes and ITF (interleaved 2 of 5) coded barcodes into your Word document.
The plugin does not need any special fonts to create a barcode, it inserts the barcode as a word-picture composed from lines and (optional) digits. Word documents prepared this way can therefore be sent to other users without them having to install or buy a special font.
Version 3.2 supports One-Click conversion of EAN-codes.
