Best way to populate an array.

What would be the best / efficient way to populate a large 2d array? I'd like to create an array of around 50-100 'monsters' with various stats like Hit Points, Speed, Attack, Defence, something like this:

Orc

10

5

4

3

Goblin

7

8

3

3

Skeleton

12

3

5

3

etc.... At the moment I'm doing something like this:

but wondered if there's a better way?

I suspect you can do this by loading a JSON file into array (which can be a local txt imported into the files folder in your project). But I haven't done/tried this, atm I just do the same as you as my arrays are small enough.
