Split column to rows issue
Hi there,
I thought it would be a simple matter but I have not found a solution despite a few hours spent on this.
I have a table that looks like the one below, just with many more rows and values:
Key Value
| A and B | 1 |
| A and B | 2 |
| C | 3 |
| D | 4 |
| E | 5 |
| X and Y | 6 |
| X and Y | 7 |
My desired output is as below:
Key Value
| A | 1 |
| B | 2 |
| C | 3 |
| D | 4 |
| E | 5 |
| X | 6 |
| Y | 7 |
After multiple tries of split, group, split into rows, adding index and split,... , remove duplicates, I always get the result below.
Key Value
| A | 1 |
| B | 1 |
| C | 3 |
| D | 4 |
| E | 5 |
| X | 6 |
| Y | 6 |
Would anyone be able to help me on this question?
Thanks in advance!
You can try something like the following.
let Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WclRIzEtRcFLSUTJUitVB5huB+c5AljGY5QJkmYBZrkCWKZgVAVYdCeSbofHNlWJjAQ==", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [Key = _t, Value = _t]), #"Grouped Rows" = Table.Group(Source, {"Key"}, {{"AllRows", each _[Value], type table [Key=nullable text, Value=nullable text]}}), #"Added Custom" = Table.AddColumn(#"Grouped Rows", "NewKey", each [Key], type text), #"Split Column by Delimiter" = Table.ExpandListColumn(Table.TransformColumns(#"Added Custom", {{"NewKey", Splitter.SplitTextByDelimiter(" and ", QuoteStyle.Csv), let itemType = (type nullable text) meta [Serialized.Text = true] in type {itemType}}}), "NewKey"), #"Added Custom1" = Table.AddColumn(#"Split Column by Delimiter", "Position", each [AllRows]{List.PositionOf(Text.Split([Key], " and "), [NewKey])}, type text), #"Removed Columns" = Table.RemoveColumns(#"Added Custom1",{"Key", "AllRows"}), #"Renamed Columns" = Table.RenameColumns(#"Removed Columns",{{"NewKey", "Key"}, {"Position", "Value"}}) in #"Renamed Columns"From:

RitaHL Question, why not:
A 1
A 2
B 1
B 2
C 3
D 4
...
Because that's pretty easy like so:
let Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WclRIzEtRcFLSUTJUitVB5huB+c5AljGY5QJkmYBZrkCWKZgVAVYdCeSbofHNlWJjAQ==", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [Key = _t, Value = _t]), #"Changed Type" = Table.TransformColumnTypes(Source,{{"Key", type text}, {"Value", Int64.Type}}), #"Split Column by Delimiter" = Table.SplitColumn(#"Changed Type", "Key", Splitter.SplitTextByDelimiter(" and ", QuoteStyle.Csv), {"Key.1", "Key.2"}), #"Changed Type1" = Table.TransformColumnTypes(#"Split Column by Delimiter",{{"Key.1", type text}, {"Key.2", type text}}), #"Unpivoted Columns" = Table.UnpivotOtherColumns(#"Changed Type1", {"Value"}, "Attribute", "Value.1"), #"Removed Columns" = Table.RemoveColumns(#"Unpivoted Columns",{"Attribute"}) in #"Removed Columns"Hi RitaHL,
Here's an M Code solution for your query. I'll leave the code used below. Thanks. Do ping back in case of any queries or confusion. Thanks!
Code:
let
Source = #table(
{"Key", "Value"},
{{"A and B", 1}, {"A and B", 2}, {"C", 3}, {"D", 4}, {"E", 5}, {"X and Y", 6}, {"X and Y", 7}}
),
List = List.Distinct(List.Combine(List.Transform(Source[Key], each Text.Split(_, "and")))),
Table = Table.TransformColumns(Table.AddIndexColumn(Source, "Keys", 0, 1), {"Keys", each List{_}})[
[Keys],
[Value]
]
in
Table
