    Table.TransformColumns(<PreviousStepName>, {{"Data", each Table.RenameColumns(_, Table.ToRows(Mappings), MissingField.Ignore)}})

Can i follow up with this question? I have the samiliar issue. The original data comes with different 2nd column name "XXkisngihudg" but it is the same column saying "FileIDs". How to handle this issue? 

 

My data looks like this. PowerBi reads in using Row2 as default header. Can I use row 1 as default header, like "Column1", "Column2","Column3",.... This dynamic FileIDs gave me a headache to merge different data files. 

 

Thanks!
