word-to-markdown - A ruby gem to liberate content from Microsoft Word documents

Ruby

Our default content publishing workflow is terribly broken. We've all been trained to make paper, yet today, content authored once is more commonly consumed in multiple formats, and rarely, if ever, does it embody physical form. Put another way, our go-to content authoring workflow remains relatively unchanged since it was conceived in the early 80s. I'm asked regularly by government employees — knowledge workers who fire up a desktop word processor as the first step to any project — for an automated pipeline to convert Microsoft Word documents to Markdown, the lingua franca of the internet, but as my recent foray into building just such a converter proves, it's not that simple.
