Hi all,
I have the following column
Category
Bear
Bear
Pig
Pig
Parrot
Parrot
And I want to add an index by category, like this:
Category Index
Bear 1
Bear 1
Pig 2
Pig 2
Parrot 3
Parrot 3
I know I could make a custom column with an if statement, but I need it to work dynamically. Could someone advice me on the M code?
Best regards,
Morten

Hi @Anonymous ,
Please refer to the following M query:
let Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WckpNLFKK1UFiBGSmo9KJRUX5JSjMWAA=", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type text) meta [Serialized.Text = true]) in type table [Category = _t]), #"Changed Type" = Table.TransformColumnTypes(Source,{{"Category", type text}}), #"Grouped Rows" = Table.Group(#"Changed Type", {"Category"}, {{"Category Index", each _, type table [Category=text]}}), #"Added Index" = Table.AddIndexColumn(#"Grouped Rows", "Index", 1, 1), #"Expanded Category Index" = Table.ExpandTableColumn(#"Added Index", "Category Index", {"Category"}, {"Category Index.Category"}), #"Changed Type1" = Table.TransformColumnTypes(#"Expanded Category Index",{{"Index", type text}}), #"Added Custom" = Table.AddColumn(#"Changed Type1", "Category Index", each [Category Index.Category] &" " &[Index]), #"Removed Columns" = Table.RemoveColumns(#"Added Custom",{"Category", "Category Index.Category", "Index"}) in #"Removed Columns"
The result will like below:

Hi @TeigeGao and @Zubair_Muhammad ,
Thank you for that.
I was actually looking for the following table (sorry for sloppy explenation):
Category | Index |
Bear | 1 |
Bear | 1 |
Pig | 2 |
Pig | 2 |
Parrot | 3 |
Parrot | 3 |
But I could still use your code to create the column.
Thank you for helping me out on this one!
Have a good day
Best ,
Morten
Hi @Anonymous
Using Query Editor..
You can Groupby the Category column >>> then add an index Column>>>then expand it
This way same category items will have same index number
