    TomJWhite Well, in Power Query you could split the column based on the : but there is also Text.BeforeDelimiter so you could do:

     

    if [ContentType] = "TV" then Text.BeforeDelimiter([Title],":") else [Title]

     

    In DAX you would do something like:

     

    Column = 
  IF(
    [ContentType] = "TV",
    LEFT([Title],SEARCH(":",[Title])-1),
    [Title]
  )

Hi TomJWhite 

 

Yes, M is more intuitive for text munipulation. You need to observe the data, if it is always to extract the first ":" then it is simple

let
    Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WcirKz8/OqcxT8MvMS9UFEVYKwamJxfl5CsZWCu5FqekKiXkpCj6JRUWVChquBZnF+SmpCkZGmkqxsQA=", 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 Custom" = Table.AddColumn(#"Changed Type", "Custom", each Text.BeforeDelimiter([Column1],":"))
in
    #"Added Custom"
