Query regarding merging

[SushainKoul]

FirstName	LastName	Country	Col4
Rajesh	Tejwani	India	null
S	K	Sharma	Britain
M	K	Gandhi	NewYork
Krishna	Kumar	India	null

This is the table that was given to me in a client interview. I was asked to get both SK and MK together as first name and Sharma and Gandhi as last name. Can anyone tell me how to do this and get the below mentioned output?

FirstName	LastName	Country	Col4
Rajesh	Tejwani	India	null
SK	Sharma	Britain	null
MK	Gandhi	New York	null
Krishna	Kumar	India	null

Hi, @SushainKoul 

I assume that  it will change when the name length is less than 2.

Create a copy table, add a condition column to get the first name.

Now transform table with M code:

let
    Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WCkrMSi3OUNJRCknNKk/MywSyPPNSMhOBdF5pTo5SrE60UjCQ4w3EwRmJRbkgGaeizJLEzDywpC9U0j0xLyUDpN0vtTwyvygbLOldlFmckQfS4l2am1iEYXgsAA==", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [FirstName = _t, LastName = _t, Country = _t, Col4 = _t]),
    #"Changed Type" = Table.TransformColumnTypes(Source,{{"FirstName", type text}, {"LastName", type text}, {"Country", type text}, {"Col4", type text}}),
    Custom1 = Table.ToRecords(#"Changed Type"),
    Custom2 = List.Transform(Custom1, each Record.ToList (_)),
    Custom3 = List.Transform(Custom2, each if Text.Length(_{1})<2 then List.Range(_,1,99) else _
),
    Custom4 = List.Zip(Custom3
),
    Custom5 = Table.FromColumns(Custom4
),
    #"Removed Columns1" = Table.RemoveColumns(Custom5,{"Column4"}),
    #"Added Index" = Table.AddIndexColumn(#"Removed Columns1", "Index", 0, 1, Int64.Type),
    #"Merged Queries" = Table.NestedJoin(#"Added Index", {"Index"}, _GetFirstName, {"Index"}, "Table (2)", JoinKind.LeftOuter),
    #"Expanded Table (2)" = Table.ExpandTableColumn(#"Merged Queries", "Table (2)", {"FirstName"}, {"FirstName"}),
    #"Reordered Columns" = Table.ReorderColumns(#"Expanded Table (2)",{"Column1", "FirstName", "Column2", "Column3", "Index"}),
    #"Removed Columns" = Table.RemoveColumns(#"Reordered Columns",{"Column1"})
in
    #"Removed Columns"

Result:

Finally, merge the two tables according to the Index column to get the first name

Please refer to the attachment below for details

Is this the result you want? Hope this is useful to you

Hi, @SushainKoul 

I am not sure if I understood your question correctly, but I suggest doing this in Power Query Editor.

All steps are in the sample pbix file.

@Jihwan_Kim Thank u for your help. Yes I know it has to be done in Query Editor but I failed to answer this how to do it in Power Query Editor in the client interview.
