Add sections of a table column as new Columns - Power Query - excel

Question

I am having the following Unpivoted table that contains Stat-tested % values and their Stat-letters and Stat-Letters position indicators on separate rows.
----------------------------------------
CODE | ATTR | TEXT | VALUE
----------------------------------------
1 mean I love it 0.45
2 mean I love it 0.67
3 mean I love it 0.49
4 mean I love it 0.21
5 mean I love it 0.66
1 mean I love it abd
2 mean I love it e
3 mean I love it cd
4 mean I love it a
5 mean I love it ab
1 mean I love it 1
2 mean I love it 1
3 mean I love it 1
4 mean I love it 1
5 mean I love it 1
1 wt-mean I hate it 0.22
2 wt-mean I hate it 0.56
3 wt-mean I hate it 0.13
4 wt-mean I hate it 0.89
5 wt-mean I hate it 0.50
1 wt-mean I hate it ab
2 wt-mean I hate it ae
3 wt-mean I hate it c
4 wt-mean I hate it b
5 wt-mean I hate it de
1 wt-mean I hate it 1
2 wt-mean I hate it 1
3 wt-mean I hate it 1
4 wt-mean I hate it 1
5 wt-mean I hate it 1
I want to group on the CODE column and add the Stat-tested Letters and position indicators as separate columns like below:
----------------------------------------------------------------
CODE | ATTR | TEXT | VALUE LETTERS POSITION
----------------------------------------------------------------
1 mean I love it 0.45 abd 1
2 mean I love it 0.67 e 1
3 mean I love it 0.49 cd 1
4 mean I love it 0.21 a 1
5 mean I love it 0.66 ab 1
1 wt-mean I hate it 0.22 ab 1
2 wt-mean I hate it 0.56 ae 1
3 wt-mean I hate it 0.13 c 1
4 wt-mean I hate it 0.89 b 1
5 wt-mean I hate it 0.50 de 1
The problem i am encountering while grouping the data on Value column, is that the column has mixed data types (text, number). How to split these into individual columns as shown below?

You can insert new custom-columns for this, check with try if the value is a number.
My Source is Tabelle1
let
Quelle = Excel.CurrentWorkbook(){[Name="Tabelle1"]}[Content],
Change_Type = Table.TransformColumnTypes(Quelle,{{"CODE", Int64.Type}, {"ATTR", type text}, {"TEXT", type text}, {"VALUE", type any}}),
Custom_Number = Table.AddColumn(Change_Type, "Number", each if try Number.From([VALUE]) < 1 otherwise null = true then [VALUE] else null),
Custom_Letters = Table.AddColumn(Custom_Number, "Letters", each if (try Number.From([VALUE]) >= 1 otherwise null) = null then [VALUE] else null),
#"Hinzugefügte benutzerdefinierte Spalte" = Table.AddColumn(Custom_Letters, "POSITION", each if [Number] = null and [Letters]= null then [VALUE] else null),
Grouped_Rows = Table.Group(#"Hinzugefügte benutzerdefinierte Spalte", {"CODE", "ATTR", "TEXT"}, {{"VALUE", each List.Max([Number]), type nullable number}, {"LETTERS", each List.Max([Letters]), type nullable text}, {"POSITION", each List.Max([POSITION]), type nullable number}})
in
Grouped_Rows
