Hi,
This is an exemple of what I have :
Questions | Answers |
Id | 1 |
Question 1 | A |
Question 2 | A |
Question 3 | A |
Id | 2 |
Question 1 | B |
Question 2 | B |
Question 3 | B |
Id | 3 |
Question 1 | C |
Question 2 | C |
Question 3 | C |
And this is what I want to get :
ID | Question1 | Question2 | Question3 |
1 | A | A | A |
2 | B | B | B |
3 | C | C | C |
Thank you
Solved! Go to Solution.
Something like this (substitute YourTable with your table name):
let
Source = YourTable,
#"Changed Type" = Table.TransformColumnTypes(Source,{{"Questions", type text}, {"Answers", type text}}),
#"Grouped Rows" = Table.Group(#"Changed Type", {"Questions"}, {{"Rows", each [Answers], type {text}}}),
#"Transposed Table" = Table.Transpose(#"Grouped Rows"),
#"Promoted Headers" = Table.PromoteHeaders(#"Transposed Table", [PromoteAllScalars=true]),
#"Changed Type1" = Table.TransformColumnTypes(#"Promoted Headers",{{"Id", type any}, {"Question 1", type any}, {"Question 2", type any}, {"Question 3", type any}}),
Custom1 = Table.FromRows(List.Zip(Record.FieldValues(#"Changed Type1"{0})), Table.ColumnNames(#"Changed Type1"))
in
Custom1

Hi @artemus.,
very interesting solution, I did not even think into this direction.
I think you can slightly modify it to something like this to reduce compute-greedy transformations.
let
Source=...
#"Changed Type" = Table.TransformColumnTypes(Source,{{"Questions", type text}, {"Answers", type text}}),
#"Grouped Rows" = Table.Group(#"Changed Type", {"Questions"}, {{"Rows", each [Answers], type {text}}}),
Output = Table.FromColumns(#"Grouped Rows"[Rows], #"Grouped Rows"[Questions])
in
Output
Kind regards,
JB
You're a genius angel. Thanks a lot!
Presuming that you are power querying in excel
let
Source = Excel.CurrentWorkbook(){[Name="Table1"]}[Content],
#"Changed Type" = Table.TransformColumnTypes(Source,{{"Questions", type text}, {"Answers", type any}}),
#"Added Custom" = Table.AddColumn(#"Changed Type", "ID", each if [Questions] = "Id" then [Answers] else null),
#"Filled Down" = Table.FillDown(#"Added Custom",{"ID"}),
#"Filtered Rows" = Table.SelectRows(#"Filled Down", each ([Questions] <> "Id")),
#"Pivoted Column" = Table.Pivot(#"Filtered Rows", List.Distinct(#"Filtered Rows"[Questions]), "Questions", "Answers", List.Min)
in
#"Pivoted Column"
