I can't figure out to program this, please help!

I have rows of data like this:
Name | Quantity | Attribute 1 | Attribute 2
EX1 | 2 | att1 | att2
EX2 | 3 | att1 | att2
EX3 | 2 | att1 | att2

I want it to expand the quantities into rows to look like this:
Name | attribute 1 | attribute 2 | etc
EX1 | att1 | att2
EX1 | att1 | att2
EX2 | att1 | att2
EX2 | att1 | att2
EX2 | att1 | att2
EX3 | att1 | att2
EX3 | att1 | att2

The Attribute 1 column and Attribute 2 column are just columns that
hold data that needs to be copied to each row.

This is to make a mail merge with multiple labels with the same
information!
