How to use Power Query to Combine Multiple Files that have different headings

When using Power Query to Combine Files from a folder there is a problem that only the 1st file's headings are used in the output. If a later file has a new heading it won't appear. 1 line of code courtesy of Gil Ravi fixes this = List.Union (List.Transform( PreExpand[Transform File], each Table.ColumnNames(_)) ) Here's Gil's post on this https://datachant.com/2017/02/07/powe... And a post relating to changing column types without referencing column names: https://datachant.com/2016/10/07/robu... Gil's book: https://www.amazon.com/Collect-Combin... Download the files: https://aasolutions.sharepoint.com/:f... Good option suggested from Muneer Marzouq on LinkedIn is that after drilling down you could just wrap the formula in Table.Combine( ) . The downside is you lose the source file names - the upside is it's easier to remember 😁 Connect with me https://wyn.bio.link https://accessanalytic.com.au/
