    Hi Nick2,

     

    To operate one time, you can click Advanced Editor and add M code like pattern below:

    let
    Source = ......,
    #"Changed Type" = ......,
    #"Step 1" = Table.SplitColumn(#"Changed Type", "Column1", Splitter.SplitTextByDelimiter(" ", QuoteStyle.Csv), {"Column1.1", "Column1.2"}),
    #"Changed Type1" = Table.TransformColumnTypes(#"Step 1",{{"Column1.1", type text}, {"Column1.2", type text}}),
    #"Step 2" = Table.SplitColumn(#"Changed Type1", "Column2", Splitter.SplitTextByDelimiter(" ", QuoteStyle.Csv), {"Column2.1", "Column2.2"}),
    #"Changed Type2" = Table.TransformColumnTypes(#"Step 2",{{"Column2.1", type text}, {"Column2.2", type text}}),
    #"Step 3" = Table.SplitColumn(#"Changed Type2", "Column3", Splitter.SplitTextByDelimiter(" ", QuoteStyle.Csv), {"Column3.1", "Column3.2"}),
    #"Changed Type3" = Table.TransformColumnTypes(#"Step 3",{{"Column3.1", type text}, {"Column3.2", type text}})
    ......
    #"Changed TypeN" = Table.TransformColumnTypes(#"Step N",{{"ColumnN.1", type text}, {"ColumnN.2", type text}})
in
    #"Changed TypeN"

Hi Nick2,

 

Click Editor Queries-> Transform, then click on the columns you want to split and click Split Column.

    Hey

     

    that's what I wanted to do, but as soon as I select more then one column the button becomes gray and I can't use it.

    Do you have any explanation or tipp  why this might be the case and how I can solve it?

        That did work, thank you very much!
        Maybe for other people with the same problem and not much knowledge in M, what I did is do it by hand one time, copy the code and just change the adress it was referring to.
