Generating Fixed-Width Files With Power Query

Chris Webb shows how to generate fixed-width files using Power Query inside Excel:

While it’s fairly common to need to load fixed-width files using Power Query or Power Query (and there’s a nice walkthrough of how to do this here), occasionally you might want to use Power Query and Excel to create a fixed-width output for another system, or maybe to create some test data. You might not want to do it often but I can imagine that when/if Power Query is integrated into SSIS this will be a slightly less obscure requirement; at the very least, this post should show you how to use a couple of M functions that are under-documented.

I don’t see this being a particularly common request, but I guess I can see some scenario in which we’re loading data into a legacy system.
