Now Christmas is already around the corner and I thought that a voucher template in Excel is perhaps even feasible . And indeed , if you load an image in the header of an Excel sheet , it is automatically displayed on the whole page in the background . Although Excel does have a background-image-function, but this shows the image only during editing and not in the putput of the printer ! Well , the Excel-template with a voucher , which I offer here for free download, contains definitely a coupon text that is customizable . The word Certificate and the framework around it , however, is in the background image and is thus fixed .
