    Hi lishapruthi ,

    Replace the expanded column names with the following code:

    List.Distinct(List.Combine(List.Transform (#"Removed Other Columns1"[Transform File],each Table.ColumnNames(_))))

An automated query is executed here:

Hi Anonymous ,

 

But is there any solution to get columns dynamically because everytime new file added in the folder there willl be more columns than previous files. In that case, we cannot update in powerquery everytime. it should be added automatically.How can we solve this issue.

 

Thanks, 

Lisha

      Hi,

       

      This solution is the closest I've come to being able to do this. I'm running into an error though. I have 4 files in a folder and I'm getting the following error at this last step. It may be because only one of my files says it's setup as a table. If so, could you help guide me?
