Replace value in a field type date

Anonymous, Greg_Deckler

thanks both of you for supporting me.

Well, as I told in my previous post I decided to start from scratch.

This time I selected Do not detect data type in Data Type Detection.

I was able to change in the column "Data Documento" the string "00.00.0000" into "".

Then I trasformed in the proper data type.

Now empty fields are showed as blank

Here the query in case you have some further advices.

let
    Source = Csv.Document(File.Contents("D:\Lavori\01.20_-_ POWER BI DATASOURCE\Delivery Dashboard\ZCSDLV.CSV"),[Delimiter="|", Columns=76, Encoding=1252, QuoteStyle=QuoteStyle.None]),
    #"Change Type" = Table.TransformColumnTypes(Source,{{"Column1", type text}, {"Column2", type text}, {"Column3", type text}, {"Column4", type text}, {"Column5", type text}, {"Column6", type text}, {"Column7", type text}, {"Column8", type text}, {"Column9", type text}, {"Column10", type text}, {"Column11", type text}, {"Column12", type text}, {"Column13", type text}, {"Column14", type text}, {"Column15", type text}, {"Column16", type text}, {"Column17", type text}, {"Column18", type text}, {"Column19", type text}, {"Column20", type text}, {"Column21", type text}, {"Column22", type text}, {"Column23", type text}, {"Column24", type text}, {"Column25", type text}, {"Column26", type text}, {"Column27", type text}, {"Column28", type text}, {"Column29", type text}, {"Column30", type text}, {"Column31", type text}, {"Column32", type text}, {"Column33", type text}, {"Column34", type text}, {"Column35", type text}, {"Column36", type text}, {"Column37", type text}, {"Column38", type text}, {"Column39", type text}, {"Column40", type text}, {"Column41", type text}, {"Column42", type text}, {"Column43", type text}, {"Column44", type text}, {"Column45", type text}, {"Column46", type text}, {"Column47", type text}, {"Column48", type text}, {"Column49", type text}, {"Column50", type text}, {"Column51", type text}, {"Column52", type text}, {"Column53", type text}, {"Column54", type text}, {"Column55", type text}, {"Column56", type text}, {"Column57", type text}, {"Column58", type text}, {"Column59", type text}, {"Column60", type text}, {"Column61", type text}, {"Column62", type text}, {"Column63", type text}, {"Column64", type text}, {"Column65", type text}, {"Column66", type text}, {"Column67", type text}, {"Column68", type text}, {"Column69", type text}, {"Column70", type text}, {"Column71", type text}, {"Column72", type text}, {"Column73", type text}, {"Column74", type text}, {"Column75", type text}, {"Column76", type text}}),

in
    #"Filtered Rows5"

Thanks again for your kind support
