@ritanoori , Try something like

if Value.Is(Text.Start([description],9) Int64.Type) then "Y" else if Value.Is(Text.Start([description],9) Text) then "X" else "N/A"

Hi @ritanoori ,

You can create this custom column in power query:

    Table.AddColumn(
        #"Changed Type", 
        "Custom", 
        each if 
            Value.Is(
                 Value.FromText(Text.Start([description],9)),Int64.Type
            ) 
        then "X"
        else if 
        Text.Length(
            Text.Remove(
                Text.Start([description],9),
                {"a".."z","A".."Z"})
            ) = 0
        then "Y"
        else "N/A"
    )

@ritanoori , Try a new column like

 

new column =
var _chk = left([description],9)
return
Switch(True(),
ISNUMBER(_chk), "Y"
ISTEXT(_chk) ,"X"
,"N/A")

Thanks. But I need this in power querey. 

@ritanoori , Try something like
