power query split column by variable positions
Hi Community
I need to split Column1 based on variable postions from Custom.1 column. Same postion values stored as a list in Custom.3 column
I have tried using the list as an argument in Splitter.SplitTextByPositions but it didn't work
Thanks in advance
| Column1 | Custom.1 |
| A B C | 0;2;4 |
| 4 5 6 | 0;2;4 |
| A B C | 0;8;16 |
| 1 2 3 | 0;8;16 |
| A B C | 0;3;8 |
| 11 22 33 | 0;3;8 |
Use below formula in a custom column
= Splitter.SplitTextByPositions(List.Transform(Text.Split([Custom.1],";"),each Number.From(_)))([Column1])See the working here - Open a blank query - Home - Advanced Editor - Remove everything from there and paste the below code to test
let Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WclRwUnBW0lEysDayNlGK1YlWMlEwVTBDEUGosbA2NAMLGSoYKRijCiFUGVtbQBQBVQGVGaMIOjo51xgaGZuYQkWBVsQCAA==", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [Column1 = _t, Custom.1 = _t]), #"Added Custom" = Table.AddColumn(Source, "Custom", each Splitter.SplitTextByPositions(List.Transform(Text.Split([Custom.1],";"),each Number.From(_)))([Column1])) in #"Added Custom"

However, I modified it to CSV rather than JSON as below
Thanks again
let Source = Csv.Document( "Column1,Custom.1 A B C,0;2;4 4 5 6,0;2;4 A B C,0;8;16 1 2 3,0;8;16 A B C,0;3;8 11 22 33,0;3;8",2,","), #"Promoted Headers" = Table.PromoteHeaders(Source, [PromoteAllScalars=true]), #"Added Custom" = Table.AddColumn(#"Promoted Headers", "Custom", each Splitter.SplitTextByPositions(List.Transform(Text.Split([Custom.1],";"),each Number.From(_)))([Column1])), #"Extracted Values" = Table.TransformColumns(#"Added Custom", {"Custom", each Text.Combine(List.Transform(_, Text.From), ":"), type text}) in #"Extracted Values"
