Multiple transformations on a table not yet expanded

Hello all,

 

I have any number of Excelfiles I grab from a Share Point folder. These are filtered down to filename and [table].

Before I can combine them, I need to a) Skip rows and b) Promote headers for each Table

I can do it for any single step, but I'm stuck at combining these steps (marked -->) in one single transform.

I think I only miss some code formatting rules, so please be kind with me 🙂

 

Thank you
Hoschi

#"Expanded Excel_File.Data" =
        Table.ExpandTableColumn(
            Table.TransformColumns(
                #"Source",
                {
                    {
                    "Excel_File.Data",
-->                    each Table.Skip(_,10),
-->                    each Table.PromoteHeaders(_, [PromoteAllScalars=true])
                    }
                }
            ),    
            "Excel_File.Data",
             {"Column1", "Column2", "Column3", "Column4"},
             {"Excel_File.Data.Column1", "Excel_File.Data.Column2", "Excel_File.Data.Column3", "Excel_File.Data.Column4"}
        )

Hi @Hoschi

 

You can add a step with below code to transform the table column. Then expand it. 

= Table.TransformColumns(#"previous step name", {{"Data", each Table.PromoteHeaders(Table.Skip(_,10),[PromoteAllScalars=true])}})
