add countblank to table.profile
Hi, I use table.profile to get the data profile of a large dataset with many columns. I believe NullCount does not count Blank cells. How can i add CountBlank to this profile? Thanks.

I don't think you can have blanks for numerical fields - they get converted to nulls, and you cannot replace values with blanks, so I am assuming this is text.let Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WSlTSUTIEYhOlWJ1opSQUXjKUB+akgBhQNoRpCGanQRUBebEA", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [#"Data 1" = _t, #"Data 2" = _t, #"Data 3" = _t]), #"Changed Type" = Table.TransformColumnTypes(Source,{{"Data 2", type number}, {"Data 3", type number}}), Custom1 = Table.Profile( #"Changed Type", { { "Blanks", each Type.Is(_, type nullable any), each List.Count(List.Select(_, each _ = "")) } } ) in Custom1This is my dummy data:
And this is the result. Note: I removed a bunch of columns Table.Profile generates to get this screenshot:
just use this:
let
Source = Sql.Database("SESKRUTDEVDB05", "REF_PDT"),
dbo_ODS_PDT_MARQUE = Source{[Schema="dbo",Item="ODS_PDT_MARQUE"]}[Data],
Custom1 =
Table.Profile(
dbo_ODS_PDT_MARQUE,
{
{
"Blanks", each Type.Is(_, type nullable any), each List.Count(List.Select(_, each _ = ""))
}
}
)
in
Custom1You don't need a Changed Type step because your data is coming from SQL Server and already has good data types.
thank you very much
