Random Sorting and Grouping into 10

Hi All, 

 

i have a list of persons i want to sort first random and then group into a group size of two persons for each group. Does anyone have a idea how to do this smart? 

 

I figured out if RandomNumber oder RandomNumberBetween or ListRandom worked, but it didn't the way i did ... 

 

see the picture below to maybe get clearer what i am trying to reach for.

Thank you for your help!

See the working here - Open a blank query - Home - Advanced Editor - Remove everything from there and paste the below code to test

let
    Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WCkgtKs7PU3BUitWBc5yQOc7IHBdkjisyxw2Z447M8UDmeCrFxgIA", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [Data = _t]),
    #"Added Custom" = Table.AddColumn(Source, "Custom", each Number.Random(), type number),
    #"Sorted Rows" = Table.Sort(Table.Buffer(#"Added Custom"),{{"Custom", Order.Ascending}}),
    #"Added Index" = Table.AddIndexColumn(#"Sorted Rows", "Index", 1, 1, Int64.Type),
    #"Divided Column" = Table.TransformColumns(#"Added Index", {{"Index", each _ / 2, type number}}),
    #"Rounded Up" = Table.TransformColumns(#"Divided Column",{{"Index", Number.RoundUp, Int64.Type}}),
    #"Added Custom1" = Table.AddColumn(#"Rounded Up", "Group", each "Group "&Text.From([Index])),
    #"Removed Columns" = Table.RemoveColumns(#"Added Custom1",{"Custom", "Index"})
in
    #"Removed Columns"

Hi Vijay_A_Verma, 

 

thanks! This is a great idea! As i had to do a similar thing with groups of ten i then added a index with steps of 0.1 and used then RoundNumbers - also worked fine and is similiar to your solution. 

 

Best regards + happy weekend!
