How to seperate particular text from a column and paste into another column.

but if you need it here's the full code from the query:

let
Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45W8sxLy7dS8DFQitWJVgpKTbNScPRxQXB8DJViYwE=", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [Column1 = _t]),
#"Changed Type" = Table.TransformColumnTypes(Source,{{"Column1", type text}}),
#"Added Custom1" = Table.AddColumn(#"Changed Type", "Custom.1", each let
L0Index = Text.PositionOf([Column1], "L0"),
L1Index = Text.PositionOf([Column1], "L1"),
L0 = if L0Index <> -1 then Text.Middle([Column1], L0Index, 2) else null,
L1 = if L1Index <> -1 then Text.Middle([Column1], L1Index, 2) else null,
Result = if L0 <> null and L1 <> null then L0 & ", " & L1 else if L0 <> null then L0 else if L1 <> null then L1 else null
in
Result)
in
#"Added Custom1"
