Use List entry in Table.SelectRows function
Hi TLGemp,
Here is query table code that I used to transform table structure based on 'transpose table' and 'remove blank row' functions to output expected table structure without specific column names as conditions, you can try it if helps:
let Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WUtKBoVgdLLyU1GJDiEhZYo4hkqgRXNQISdQYLmqsFBsLAA==", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [Column1 = _t, Column2 = _t, Column3 = _t, Column4 = _t]), #"Removed Blank Rows" = Table.SelectRows(Source, each not List.IsEmpty(List.RemoveMatchingItems(Record.FieldValues(_), {"", null}))), #"Transposed Table" = Table.Transpose(#"Removed Blank Rows"), #"Removed Blank Rows1" = Table.SelectRows(#"Transposed Table", each not List.IsEmpty(List.RemoveMatchingItems(Record.FieldValues(_), {"", null}))), #"Promoted Headers" = Table.PromoteHeaders(#"Removed Blank Rows1", [PromoteAllScalars=true]), #"Changed Type" = Table.TransformColumnTypes(#"Promoted Headers",{{"des1", type text}, {"des2", type text}, {"des3", type text}}) in #"Changed Type"Regards,

Source value - the column of des1,des2,des3 can vary and is not always the same
| null | null | null | null |
| null | null | null | null |
| null | des1 | null | val1 |
| null | des2 | null | val2 |
| null | des3 | null | val3 |
Result
| des1 | des2 | des3 |
| val1 | val2 | val3 |
let
Quelle = Excel.CurrentWorkbook(){[Name="Tabelle4"]}[Content],
#"Geänderter Typ" = Table.TransformColumnTypes(Quelle,{{"Column1", type any}, {"Column2", type text}, {"Column3", type any}, {"Column4", type text}}),
#"Tiefer gestufte Header" = Table.DemoteHeaders(#"Geänderter Typ"),
#"Transponierte Tabelle" = Table.Transpose(#"Tiefer gestufte Header"),
#"Gefilterte Zeilen" = Table.SelectRows(#"Transponierte Tabelle", each ([Column4] = "Des1")),
Column1 = #"Gefilterte Zeilen"[Column1],
Benutzerdefiniert1 = Table.SelectRows(Quelle, each ([Column2] <> null))
in
Benutzerdefiniert1
In the line Benutzerdefiniert1 I would like to use the list Column1 from the line above instead of the static [colum2]. This should make the code more dynamic.
