Just to clarify, so you have a large list like
Name Answer
aaa 1
aaa 2
bbb 3
...
And you want a list like
Name Answer
aaa 1, 2
bbb 3
...
right?
Do the following:
1. Click a cell in your list
2. Invoke Excel->DigDB->Unique->Extract Uniques->from Table Column(s)
3. Use first dropdown to select the "Name" column
4. Tick the "optional" filed, use the 2nd dropdown to select the "Answer" column
5. click ok.
You can try this in a small table a few times to get a hang of how it works, then apply it on your large table.
