Generate random list without duplicates

[jaryszek]

hi Guys,

I want it generate list from 1 to 13 and after that shuffle this list to get not sorted numbers. How can I do this ?

Iist.number and number.roundbetween are generating duplicates...

Best

Thank you very much! 

Can I do this only with a list without adding new column ?

Hi @jaryszek,

Create custom column with numbers i.e. 1-100 and sort by this random column. After sort you can delete Random column.

let
    Source = Table.FromList({1..13}, Splitter.SplitByNothing(), type table[Numbers = Int64.Type]),
    Ad_Random = Table.AddColumn(Source, "Random", each Number.Round(Number.RandomBetween(1, 100), 0), Int64.Type),
    #"Sorted Rows" = Table.Sort(Ad_Random,{{"Random", Order.Ascending}})
in
    #"Sorted Rows"

I simply don't understand why - bacause you can just delete Random column after sorting... But if you don't want see that step as separate column - you can merge that steps into 1 for example: 

let
    Source = Table.FromList({1..13}, Splitter.SplitByNothing(), type table[Numbers = Int64.Type]),
    Randomized = Table.RemoveColumns(Table.Sort(Table.AddColumn(Source, "Random", each Number.Round(Number.RandomBetween(1, 100), 0), Int64.Type),{{"Random", Order.Ascending}}),{"Random"})
in
    Randomized
