I have a table in PowerBI which I want to transform using PowerQuery. I am trying to do the PowerQuery equivalent of applying the python function value_counts() to every column in the dataframe. However, I cannot find a way to do it.
df.apply(pd.Series.value_counts)
As an example, I have this dataframe:
When I apply the python code to it, it results in this dataframe:
I would be grateful for any ideas, thank you

Hi @Anonymous
You can use this code in Power Query, just update the Source:
let
Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WKkvMKU2NN1TSgbKM4CwTOMsUiRWrg08PdnOw6UGwjLGy8NtjjNWV+O3BZiPQbbEA", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [#"Day 1" = _t, #"Day 2" = _t, #"Day 3" = _t, #"Day 4" = _t, #"Day 5" = _t]),
UnpivotedColumns = Table.UnpivotOtherColumns(Source, {}, "Attribute", "Value"),
GroupedRows = Table.Group(UnpivotedColumns, {"Attribute", "Value"}, {{"Count", each Table.RowCount(_), type number}}),
#"Pivoted Column" = Table.Pivot(GroupedRows, List.Distinct(GroupedRows[Attribute]), "Attribute", "Count", List.Sum)
in
#"Pivoted Column"
The sample file is attached.
