Questions about tilesets

I'm hijacking the topic to ask a related question. Is there any way a tilemap can easily be exported into a matrix, so that numbers and letters can represent the tiles? Or would one have to write a tool for that?

It's already the case, I think in-game it's just a single-dimension array and "lines and columns" are defined by the width and height of the map, but the game does not really have the notion of this being a 2D array. Zone Doctor can export all layers tilemaps in binary format.
