How to transform excel text list to table
Hi Murat62,
I'm not sure if I get this straight, but based on what you had said, my understanding is the following:
The category column (named Column) is recursive, and whenever the sequence starts from the beginning (with "A" value), the record number increases with 1.
So, based on it, I don't know if there's any solution in the Power Query for that matter, but I figured out a way in Excel: if you create a new column with the following formula, you'll get the record numbers:
=IFERROR(IF(A1>A2;C1+1;C1);1)
If you load this table into PBI, you can create the pivot table in the Power Query you wanted. (with Column From Examples or even in Excel with the concatenate formula you can get the "record 1", "record 2"... format easily)
Let me know please if it solves your problem and whether it was helpful or not.
Best regards,
Andris

In Power Quey, you can:
buffer the table,
group on "Column", chosing operation "All Rows",
adjust the generated code to have an index column added to the nested tables,
expand the nested tables,
pivot the column "Column" with advanced option "Don't Aggregate" and
as a finishing touch you may add prefix "Record " to the record numbers.
let
Source = Table.Buffer(ExcelTextList),
#"Grouped Rows" = Table.Group(Source, {"Column"}, {{"AllRows", each Table.AddIndexColumn(_, "Record", 1, 1), type table}}),
#"Expanded AllRows" = Table.ExpandTableColumn(#"Grouped Rows", "AllRows", {"Text ", "Record"}, {"Text ", "Record"}),
#"Pivoted Column" = Table.Pivot(#"Expanded AllRows", List.Distinct(#"Expanded AllRows"[Column]), "Column", "Text "),
#"Added Prefix" = Table.TransformColumns(#"Pivoted Column", {{"Record", each "Record " & Text.From(_, "en-US"), type text}})
in
#"Added Prefix"
Hi MarcelBeug,
Your method is lovely, but according to my understanding, this - way because of the Group By - it gets the record numbers by the characters (so the first "A" will get 1, the second "A" get 2... the first "E" get 1), instead of the alphabetical order of the "sequences" (so the first sequence of 4 types "A, B, C, D" should get the record number 1, and after the second sequence of 5 "A, B, C, D, E" should get the record number 2).
Here's what Murat62 showed in the original post,And that's what you get with your formula.

andris_ Oops, you're right.
Your Excel solution, translated to Power Query, could look like:
let
Source = Table.Buffer(ExcelTextList),
Accumulation = List.Skip(List.Accumulate(Source[Column],{{Source[Column]{0},0}},(r,c) => r & {{c, if List.Last(r){0} >= c then List.Last(r){1} + 1 else List.Last(r){1}}})),
Tabled = Table.FromRows(Accumulation),
Combined = Table.FromColumns(Table.ToColumns(Source)&{Tabled[Column2]}, Value.Type(Table.AddColumn(Source, "Record", each null, Int64.Type))),
#"Pivoted Column" = Table.Pivot(Combined, List.Distinct(Combined[Column]), "Column", "Text "),
#"Added Prefix" = Table.TransformColumns(#"Pivoted Column", {{"Record", each "Record " & Text.From(_, "en-US"), type text}})
in
#"Added Prefix"Can you explain please how exactly the code works (until the pivot part), what does it exactly do? It's working to me, but I can't totally understand every step of the formulas.
