Removing Duplicates

[kirabray]

Hello,

I have duplicates in my data that are similar but not exact dupes (ie John_Smith and John_Smi). How am I able to consolidate these two but keep the ones that will be changing as their own distinct rows, just under the new name?

Hi @kirabray ,

Here I create a sample to have a test. I suggest you to try fuzzy merge and then do some transformations in Power Query Editor.

My Sample:

M Query:

let
    Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45W8srPyIsPzs0syVCK1UFwwZygzOT8+KiM/FIUqRJkOSS2UmwsAA==", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [Name = _t]),
    #"Changed Type" = Table.TransformColumnTypes(Source,{{"Name", type text}}),
    #"Merged Queries" = Table.FuzzyNestedJoin(#"Changed Type", {"Name"}, #"Changed Type", {"Name"}, "Changed Type", JoinKind.LeftOuter, [IgnoreCase=true, IgnoreSpace=true, Threshold=0.1]),
    #"Expanded Changed Type" = Table.ExpandTableColumn(#"Merged Queries", "Changed Type", {"Name"}, {"Changed Type.Name"}),
    #"Added Custom" = Table.AddColumn(#"Expanded Changed Type", "Custom", each Text.Length([Changed Type.Name])),
    #"Added Custom1" = Table.AddColumn(#"Added Custom", "Custom.1", each List.Max(
let _Name = [Name] in
Table.SelectRows(#"Added Custom",each _Name = [Name])[Custom])),
    #"Removed Duplicates" = Table.Distinct(#"Added Custom1", {"Custom", "Custom.1", "Changed Type.Name"}),
    #"Filtered Rows" = Table.SelectRows(#"Removed Duplicates", each ([Custom] = [Custom.1])),
    #"Removed Columns" = Table.RemoveColumns(#"Filtered Rows",{"Changed Type.Name", "Custom", "Custom.1"})
in
    #"Removed Columns"

  Result is as below.
