Significance & Logos
Significance is visualized by matching a specific color with a specific picture or shape. The background color of Excel cells can than be visualized in PowerPoint using the corresponding shapes, e.g. arrows. Specific texts can automatically be replaced by images/logos. OfficeReports does this by looking for image files with the same name as the text in Excel in the folders you have specified. In case an image file is found, the image is shown instead of the text.
