Power Query to Concatenate Rows Based on Condition

[legalhustler]

Hi,

I have column with Names, (unique) ID, and Address. The problem is some addresses have their street address in one row and the row below it is their city, state and zip. I would like to have their street address, city, state, and zip in concatenated in on line based on their ID. For example:


Name...….....ID...……...Address

Joe Smith....123...……..25 Apple Dr.

Joe Smith.....123...…...New York City, NY, 00972

Sue Brown....445...…...90 Bayview St. Miami, FL 32423

Tim Rice...….565...…..55 Pachino St.

Tim Rice...…..565...….Rockville, MD 64310



ExpectedResult:

Joe Smith...….123......25 Apple Dr. New York City, NY, 00972
Sue Brown....445...…...90 Bayview St. Miami, FL 32423
Tim Rice...….565...…..55 Pachino St. Rockville, MD 64310


How can I transform my data to show like this?

Use Group with All Rows then List.Distinct and Extract with Space delimiter

[Table="width:, class:head"]
[tr=bgcolor:#FFFFFF][td=bgcolor:#5B9BD5]Name[/td][td=bgcolor:#5B9BD5]ID[/td][td=bgcolor:#5B9BD5]Address[/td][td][/td][td=bgcolor:#70AD47]Name[/td][td=bgcolor:#70AD47]ID[/td][td=bgcolor:#70AD47]Address[/td][/tr]

[tr=bgcolor:#FFFFFF][td=bgcolor:#DDEBF7]Joe Smith[/td][td=bgcolor:#DDEBF7]

123​

So I did Group By on the ID field > All Rows, but I don't know how to apply the List.Distinct? Should I expand the new column once I did Group By? Where do I use List.Distinct? In a Custom Column?

AS an alternative approach use Text.Combine:

let
    Source = Excel.CurrentWorkbook(){[Name="InputTable"]}[Content],
    #"Changed Type" = Table.TransformColumnTypes(Source,{{"Name", type text}, {"ID", Int64.Type}, {"Address", type text}}),
    Result=Table.Group(#"Changed Type", {"Name", "ID"}, {{"Count", each Text.Combine([Address],", "), type text}})
in
    Result

After Group you should see Table column, then use
for ID: ID = Table.AddColumn(Group, "ID", each List.Distinct(Table.Column([Count],"ID"))),
and : ExtractID = Table.TransformColumns(ID, {"ID", each Text.Combine(List.Transform(_, Text.From)), type text}),

the same for Address

Sorry Sandy666
for crossing my post with yours. I hope I haven't confused the issue.

Thank you both. I used your method as it was easy for me to understand and change the M code. Small issue, some address lines show like this in a cell:

123 Moonlight St.
Columbus, OH 57423

How can I move/display it in one line for the cell/field? Do I need to substitute hard space/line feed with regular space?

NVM, I was able to apply CLEAN and it worked. TRIM did not work.

 

[peter789]

Not sure what NVM means but I'm glad it worked and also you understood what the code was doing and helps you on your Power Query learning adventure!
