Project Medusa sets catalogues from spreadsheets: load Excel or CSV, design one template, and each record becomes a tile, a table row or a block of paragraphs. When next year’s price list arrives, Medusa matches it by item number.

Medusa matches the new price list against the typeset pages by item number: changed prices update, new items land in their place, and the program flags hand edits instead of overwriting them. For sign-off you get a proof PDF with only the changed pages.

EAN, ISBN with price add-on, UPC, Code 128, GS1-128, QR code with logo, DataMatrix and PDF417, as vectors in any colour, with check digit and human-readable text, per record too.
