Is there a way to create a script to input large amounts of data into a file or excel?

Essentially I am creating a Map. For testing purposes I would want it to be 200*600 Which is 120,000 tiles that I would like to avoid entering manually :)

I want each tile to have 10 variables and the data input to be like so:

Tile1
2
3
4
5
6
7
8
9
10
Tile2
2
3
4
5
6
7
8
9
10
Tile3
...

And so on.

I would want the script to read from different files for different variables or create random numbers between 0 and x.

IE: Variable 2 = random input from file var2.txt that has 30 different rows of different text in it all with different lengths.

Now I'm just curious how hard or complicated this would be to script. What should I script it in? I would ideally like to create something much bigger in the future, something like 2000*6000 maybe. Would MySQL be able to handle such a big database that would require an hrly refresh on certain variables?
