Question : Convert matrix values to columns

Re MS Excel2003
Help I have a large grid of data which I would like to convert
to columns (to put into a database).

In simple terms I have
(note alpha's and numerics)
X Y Z etc
A 1 2 3
B 4 5 6
C 7 8 9
etc

Which I need to convert to (note each alpha numeric is in a separate cell)
X A 1
X A 2
X A 3
Y B 4
Y B 5
Y B 6
Z C 7
Z C 8
Z C 9
etc

In reality I have something like 600 rows and 30 columns making up the data grid.
I would b grateful for any help on this please. Thanks

This appears to be working. It uses array transfers to speed things along.
