How can I do text-to-columns in Numbers? I've got a column where each cell in the column contains two different pieces of data separated by a known delimiter ", ". How can I split each cell in this column around the delimiter?

Given:

COLUMN1
-------
ABC, 123
FOO, 666
ROFL, 411


I want

COLUMN1    COLUMN2
-------    -------
ABC        123
FOO        666
ROFL       411
You can also replace the delimiters with tabs:


Copy the cells and paste them to a new TextEdit document.
Replace ", " with tab. You can insert a tab by pressing option-tab.
Copy and paste the text back to Numbers.
