Hi @Toluhenok ,

 

Try it by deleting #"Changed Type" (second last row):

Hi @Toluhenok ,

 

Here an example. Before:

After:

Here the code in Power Query M that you can paste into the advanced editor (if you do not know, how to exactly do this, please check out this quick walkthrough)

let
    Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WMlSK1YlWyivNyQEzjFC5xqhcE1SuKRI3FgA=", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [Number = _t]),
    #"Changed Type" = Table.TransformColumnTypes(Source,{{"Number", Int64.Type}}),
    #"Replace Values" = Table.ReplaceValue(#"Changed Type",each [Number],each if [Number] = null then List.Average(#"Changed Type"[Number]) else [Number], Replacer.ReplaceValue,{"Number"})
in
    #"Replace Values"

 

Let me know if this helps 🙂
