Countif in power bi

[zuriqi]

Hi

I am looking for a similar to the below formula to find the count of item in each and every row in the entire column.

=COUNTIF($A$1:A2,A2)

=COUNTIF(Table1[[#Headers],[ColA]:[ColA]]:[@ColA],[@ColA])

Yes, the original order should be retained at the end

Are you zuriqi?

zuriqi last replied on 30 May. But that's how I understood the task.


But I don't care, because when I help, it's primarily to learn for myself. And I also succeeded very well with this thread

But that's how I understood the task.

But not me, in PBI it doesn't matter too much sort order

Try this:

let
    Source = Excel.CurrentWorkbook(){[Name="Tabelle1"]}[Content],
    #"Changed Type" = Table.TransformColumnTypes(Source,{{"ColA", type text}}),
    #"Duplicated Column" = Table.DuplicateColumn(#"Changed Type", "ColA", "ColA - Copy"),
    #"Added Index" = Table.AddIndexColumn(#"Duplicated Column", "Index", 0, 1),
    #"Grouped Rows" = Table.Group(#"Added Index", {"ColA - Copy"}, {{"CountAll", each _, type table [ColA=text, #"ColA - Copy"=text, Index=number]}}),
    #"Added Custom" = Table.AddColumn(#"Grouped Rows", "Index2", each Table.AddIndexColumn([CountAll], "Index2", 1, 1)),
    #"Removed Columns" = Table.RemoveColumns(#"Added Custom",{"CountAll"}),
    #"Expanded Index2" = Table.ExpandTableColumn(#"Removed Columns", "Index2", {"ColA", "Index", "Index2"}, {"ColA", "Index", "ColB"}),
    #"Sorted Rows" = Table.Sort(#"Expanded Index2",{{"Index", Order.Ascending}}),
    #"Removed Columns1" = Table.RemoveColumns(#"Sorted Rows",{"ColA", "Index"})
in
    #"Removed Columns1"

On my computer it lasts for:

Excelguru.ca solution - about 33 seconds
My solution - 5 seconds

That's a great solution, too. At the test with 960.000 lines, it took about 13 seconds. Almost identical with the first solution from cyborgski, which takes about 12 seconds on my computer. Only the second solution of cyborgski needs about 40 seconds for this amount of data.


At the test with 120.000 lines all 3 solutions are, from the feeling, equally fast.
