Can you view & edit macros offline?

I have an old computer that really rebels switching between the game and desktop (at least since 8.3 launched) So I want to view and edit macros out of the game.

Yeah.
Check out the macros-cache.txt file in C:\Program Files (x86)\World of Warcraft\_retail_\WTF

and Account\0000000#

and 0000000#\Realm\Char

Thanks, that is the place.
