Data Matching in Excel

I have two sets of data that I need to match up. Each set has a common denominator, but there aren't an equal number of records so I can't just sort the columns by those numbers to match them up.

For example, I've got one set like this:

data,111222
data4,223333

and another like this:

data2,111222
data5,223333

I just want a result that looks like the following, matched by the common number:

data,data2
data4,data5

Is there a way to make Excel match two sets of data based on numbers in columns that match and then output required data in the format listed above? Thanks!
