Unfold a path to lines

[Ju7438]

Hello Everyone, 

Im currentky struggleling with Power BI, here is the situation, i have a table with 1 column containing multiple path with "/" as separator.

e.i :

Context

A/B/C

A1/A2/A3/A4

I need to transform it like that with 2 colums 'Name' and 'Context' :

Name	Context
A
B	A
C	A/B
A1
A2	A1
A3	A1/A2
A4	A1/A2/A3

Did someone can helping me with that ? in power query or DAX it's the same for me...

Thanks in advance !

Hi , @Ju7438 

For your need , i can be realized in Power Query Editor.

You can put this M code in "Advanced Editor" to refer to :

let
    Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WctR30ndWitUBsgz1HY30HY31HU2UYmMB", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [Context = _t]),
    #"Changed Type" = Table.TransformColumnTypes(Source,{{"Context", type text}}),
    #"Added Custom" = Table.AddColumn(#"Changed Type", "Custom", (x)=>Text.Split(x[Context],"/")       ),
    #"Added Custom1" = Table.AddColumn(#"Added Custom", "Custom2", (x)=>    
 Table.AddColumn(Table.FromColumns({{0..List.Count(x[Custom])-1}}),"test",(y)=>   Text.Combine(List.Range(x[Custom],0,y[Column1]),"/") )[test]      
  ),
    Custom1 = Table.FromColumns({List.Combine(#"Added Custom1"[Custom]) ,  List.Combine(#"Added Custom1"[Custom2])})
in
    Custom1

Then we can meet your need:

Thank you for your time and sharing, and thank you for your support and understanding of PowerBI!
