So I have a number of excel files in a folder that I want to bring into Power BI. I know there is a sample file to perform query steps on. My question is that some of the newer files in this folder have additional columns that the older files in the folder do not have. How will Power BI handle a situation like this?
Based on my research, to combine multiple Excel files from folder, those Excel workbooks should have the same structure and number of columns.
Here are some links for your reference:
The additional columns in the new files will appear as such in the appended dataset. See this video - https://www.youtube.com/watch?v=yL11ugShdrk
