edit: Added the same aproach for JSON at the bottom of this post Have you also seen alot of “Helper Queries” in Power Query when working with files from folders? I think it is very cluttered to have all these helpers laying around in the Power Query editor. What I’m used to see Above is the usual way of Power Query to handle several files in the same folder. The approach is done to have only 1 (usually the first) file to create the schema from.
The Power Query tool has just been updated and there are some pretty neat features rolled out: New Transfomation: Use Headers as First Row. Column Name field in Merge Columns dialog. Quick Access Toolbar in Query Editor dialog. Warning for stale data previews in new queries. Function Invocation from Search. Preserve Excel Number formats in the worksheet on query refresh. Along side this update – there is also an updated Salesforce connector for Power Query which you need to install after installing the above update.
