How to convert similarity ratings data into matrix?

Dear all,
I've collected similarity data on the 7-point Likert scale for a range of items (e.g., A, B, C), where participants were rating all possible combinations of these items. The results have the following format:
A, A, 7
A, B, 4
A, C, 2
B, A, 3
B, B, 7
B, C, 5
C, A, 2
C, B, 6
C, C, 7
As you can see, rating of items in reverse order (e.g., AB and BA) is not always the same.
Is there a way I can transform the data table (item1, item2, rating) into similarity matrix (like the one below)?
A, B, C
A, 7, 4, 2
B, 3, 7, 5
C, 2, 6, 7

As parth mentioned can you tell how you have stored data and in which format? It would be easier to answer you question that way.
