I have data that comes out of the system of record like this.
Item # Description
1234 Widget
1234 Blue
1234 Large
2345 Thingy
2345 Purple
3456 Gizmo
3456 Red
3456 Large
3456 Square
3456 With Buttons

How do I combine the variable number of descriptions into one field for each
item #? Each item doesn't have the same amount of descriptions.
I want the output to be like this.
Item # Description
1234 "Widget,Blue,Large"
2345 "Thingy,Purple"
3456 "Gizmo,Red,Large,Square,With Buttons"
