Macro editing outside game? (or suggestion for such)

I've done some Google searches in regards to the topic, but the posts were 6+ months old and not many had an affirmative response. Anyway:

Is it possible to edit macros outside the game? Is there an editor available? Would it be possible to make the macro files text/editable? I know where they're located but have no clue on how to edit them.

It would save me a lot of time here and there, if I were able to edit my macros outside of the game.

Thanks!
