Split several columns at once

Hey guys,

 

quick an dirty, I have a lot of columns, that need to be split. All in the same way, in several tabels. Is it possible to do this at once, at best in all tables at the same time, or at least in one table at the same time?

 

Thanks and greetings

 

Nick

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.
