The idea was that by moving the inversion into a sperate process, your main program can just read the 'correct' format from a file handle (as shown) and the memory consumption wouldn't be a burdon on your main process. Nor would you need to change the main program, except to use the special form of open for the errent file.

How big is big?

Other than re-reading and re-spliting every line once for every column in the file, there isn't another way.
