Automatic text generation

[Paul Smith]

Dear All

I have a long spreadsheet as follows:

X1	X2	X3	X4	X5
2	6	1	1	4
2	1	3	1	5
3	3	3	4	6
4	2	5	3	4
6	6	5	1	1
5	6	4	1	3

[...]

For each number and for each X variable, there is a small piece of
text. I am looking for a program to replace, for each spreadsheet line
and for each number therein, the respective text and create a phrase
concatenating the pieces of text corresponding to the numbers. Is
there some tool to accomplish this goal?

Thanks in advance,

Paul
