    Actually, it's pretty easy with this line of code:

     

    = Table.AddColumn(Source, "Custom", each Table.PromoteHeaders(Csv.Document([Content],[Delimiter=";", Encoding=1252])))

     

    Replace your Step 2&3 with it.

    It will retain all the metadata from the 1st step and add the content in an additional custom column.

    If your csv's have all the same headers, you simply expand this column and the headers of the 1st file will be shown - and expand all other files on these cols as well.

     

    If there are differnt cols - just come back & I'll post the code for the auto-expand of different headers.

Hey Imke! 

 

Thanks for all the support. 

I have a slighly different problem and since I'm new to M I don't know how to proceed. 

 

In my case, I need to keep the creation date of the document, as I may benefit from it for some calculations.

How can I transform the creation date into a new column in Power Querry?

 

Thanks
