Pranav released another drop of Open XML Diff. There are a couple of bugs fixed. Read about Open XML Diff here. This tool is a developer’s friend. When I’m writing code to generate an Open XML Document, I know how I want the document to render in Word, but am unsure about which element or attribute to tweak. So I save a copy of a doc, modify it, save it again, and compare the two. This lets me know what I want to control programmatically.
