Pivot the table

Hi guys,

 

I really need your help

 

I want to change the table (table one) from this one

 

Column1
1
A
B
2
C
3
D
E
4
F
G
5
H

 

to this one (table two)

 

NoManchesterArsenal
1AB
2C 
3DE
4FG
5H 


For table one, all the text below Number will go for Manchester, and All Text below text will go for Arsenal. That`s why if you see cell (2, Arsenal) or (5, Arsenal), you will see blank or null cell.

    let
    Source = Excel.CurrentWorkbook(){[Name="Table1"]}[Content],
    group = Table.Group(
        Source,
        "Column1", 
        {"x", (x) => x[Column1]},
        GroupKind.Local, 
        (s, c) => Number.From(c is number)
    ),
    z = Table.FromList(group[x], (x) => x, {"No", "Manchester", "Arsenal"})
in
    z

    You can extract the text into a new column using if each List.Contains({0..9}, [Column1])then [Column1] else null) and  then fill down that column. Then remove  any rows where Column1 = number column. Then group by filldown column, and extract to new columns. I can't write out the code right now, but logically, thats how I would do it.

      Dear Watkinnc, thanks for your reply

      I have been here

       


      and my current M code as below:

      let
      Source = Excel.CurrentWorkbook(){[Name="Table1"]}[Content],
      #"Changed Type" = Table.TransformColumnTypes(Source,{{"Column1", type any}}),
      #"Added Custom" = Table.AddColumn(#"Changed Type", "Custom", each if Value.Is(Number.From([Column1]), type number) then [Column1] else null),
      #"Replaced Errors" = Table.ReplaceErrorValues(#"Added Custom", {{"Custom", null}}),
      #"Filled Down" = Table.FillDown(#"Replaced Errors",{"Custom"}),
      #"AddedCustom" = Table.AddColumn(#"Filled Down", "IsNumeric", each if Value.Is(Value.FromText([Column1]), type number) then "Numeric" else "Non-numeric"),
      #"FilteredRows" = Table.SelectRows(#"AddedCustom", each ([IsNumeric] = "Non-numeric")),
      #"RemovedCustom" = Table.RemoveColumns(FilteredRows,{"IsNumeric"})
      in
      RemovedCustom

      I still don`t understand with : "Then group by filldown column, and extract to new columns", to return the final table I desired.
