Merging text in rows per unique key

Hi all,

 

Hoping this is an easy one for some of you. I have data that looks like this in the Power Query Editor that I'd like to "merge" into one row (except this is over about 250K rows):

 

Column 1 (Key)

Column 2 (Free text field)

181

This is an

181

example of the

181

data I am trying to merge

 

Hoping you may know the easiest way to do this?

 

Thank you in advance.

    Use group by in combination with Text.Combine. See the working here - Open a blank query - Home - Advanced Editor - Remove everything from there and paste the below code to test 

    let
    Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WMrQwVNJRCsnILFYAosQ8pVgdmGBqRWJuQU6qQn6aQklGKpJESmJJooKnQmKuQklRZWZeukJJvkJualE6UE0sAA==", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [#"Column 1" = _t, #"Column 2" = _t]),
    #"Grouped Rows" = Table.Group(Source, {"Column 1"}, {{"Result", each Text.Combine([Column 2]," ")}})
in
    #"Grouped Rows"
