    Check the following code on a blank query:

    let
        Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WcvVxLSxPLSqpLM3KSE9LKU6sSC5LysrLzswH85VidTDUgMUcHR0J6nNKAipBNiHYyNDIEJeGWAA=", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [#"Item Text" = _t]),
        #"Added Custom" = Table.AddColumn(Source, "Custom", each if Text.StartsWith([Item Text], "ELE") then 
    Text.Middle([Item Text], 25, Text.Length([Item Text])) else "")
    in
        #"Added Custom"

    Hi alexpork 

     

    Starting from the table where you have the Item text column, create a custom column by:

     1.  Selecting Addcolumn --> Custom column in the menu of the Query editor (https://docs.microsoft.com/en-us/power-bi/create-reports/desktop-add-custom-column)

     2. Enter this code for the column when prompted:

    = if Text.StartsWith([Item Text], "ELE") then Text.Middle([Item Text], 24, Text.Length([Item Text])-24 )) else [Item Text]

     

    Please mark the question solved when done and consider giving a thumbs up if posts are helpful.
