COUNT IF in Power Query

Hi NumerENAP

You could try below M code

let
    Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WCixNLS7JzM8zVNJRikwthpN++UqxOghpI5CQviMuaWM03SAyNhYA", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type text) meta [Serialized.Text = true]) in type table [Column1 = _t, Column2 = _t, Column3 = _t, Column4 = _t]),
    #"Changed Type" = Table.TransformColumnTypes(Source,{{"Column1", type text}, {"Column2", type text}, {"Column3", type text}, {"Column4", type text}}),
    #"Unpivoted Columns" = Table.UnpivotOtherColumns(#"Changed Type", {"Column1"}, "Attribute", "Value"),
    #"Grouped Rows" = Table.Group(#"Unpivoted Columns", {"Column1", "Value"}, {{"Count", each Table.RowCount(_), type number}}),
    #"Pivoted Column" = Table.Pivot(#"Grouped Rows", List.Distinct(#"Grouped Rows"[Value]), "Value", "Count", List.Sum),
    #"Merged Queries" = Table.NestedJoin(#"Pivoted Column", {"Column1"},#"Changed Type" , {"Column1"}, "Pivoted Column", JoinKind.LeftOuter),
    #"Expanded Pivoted Column" = Table.ExpandTableColumn(#"Merged Queries", "Pivoted Column", {"Column2", "Column3", "Column4"}, {"Pivoted Column.Column2", "Pivoted Column.Column3", "Pivoted Column.Column4"})
in
    #"Expanded Pivoted Column"

If you just want to bold result in your result, you could try below M code

let
    Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WCixNLS7JzM8zVNJRikwthpN++UqxOghpI5CQviMuaWM03SAyNhYA", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type text) meta [Serialized.Text = true]) in type table [Column1 = _t, Column2 = _t, Column3 = _t, Column4 = _t]),
    #"Changed Type" = Table.TransformColumnTypes(Source,{{"Column1", type text}, {"Column2", type text}, {"Column3", type text}, {"Column4", type text}}),
    #"Unpivoted Columns" = Table.UnpivotOtherColumns(#"Changed Type", {"Column1"}, "Attribute", "Value"),
    #"Grouped Rows" = Table.Group(#"Unpivoted Columns", {"Column1", "Value"}, {{"Count", each Table.RowCount(_), type number}}),
    #"Pivoted Column" = Table.Pivot(#"Grouped Rows", List.Distinct(#"Grouped Rows"[Value]), "Value", "Count", List.Sum),
    #"Replaced Value" = Table.ReplaceValue(#"Pivoted Column",null,0,Replacer.ReplaceValue,{"Yes", "No", "N/A"})
   
  in   #"Replaced Value"
