Power Query: Unique values in both columns
Hello all!
I have a doubt regarding Power Query.
I have 2 columns, with duplicates. I want to keep only those that are unique in both. For instance:
If I remove duplicates from column1, I only want to remove if they stay unique in column2.
I.e, if I remove row 1 I can't remove row 3 otherwise I would have two "11".
I hope my explanation made sense.
Thanks in advance.
Use below Query to achieve this output
let Source = Excel.CurrentWorkbook(){[Name="Table1"]}[Content], #"Added Index" = Table.AddIndexColumn(Source, "Index", 0, 1, Int64.Type), #"Inserted Modulo" = Table.AddColumn(#"Added Index", "Modulo", each Number.Mod([Index], 4), type number), #"Filtered Rows" = Table.SelectRows(#"Inserted Modulo", each ([Modulo] = 0 or [Modulo] = 3)), #"Removed Columns" = Table.RemoveColumns(#"Filtered Rows",{"Index", "Modulo"}) in #"Removed Columns"To achieve the below output, replace [Modulo] = 0 or [Modulo] = 3 in 5th row of the code above
with [Modulo] = 1 or [Modulo] = 2
Updated code is below
let Source = Excel.CurrentWorkbook(){[Name="Table1"]}[Content], #"Added Index" = Table.AddIndexColumn(Source, "Index", 0, 1, Int64.Type), #"Inserted Modulo" = Table.AddColumn(#"Added Index", "Modulo", each Number.Mod([Index], 4), type number), #"Filtered Rows" = Table.SelectRows(#"Inserted Modulo", each [Modulo] = 1 or [Modulo] = 2), #"Removed Columns" = Table.RemoveColumns(#"Filtered Rows",{"Index", "Modulo"}) in #"Removed Columns"
