Data Tags are the products core functionality. It represents fields and forms part of a data source which gets added to a template. Once a data tag has been dragged onto a template, it utilises a Microsoft form of placeholder which, in Word would be a "Rich Text Control" and in PowerPoint, a "Shape." At merge time DocGeneration populates the placeholders with data from the data source itself.

Output Tags (left arrow)
