In my RPG games I coded a simple database program to take the trouble away from me, well partially. I can just easily edit all the names, descriptions, and of course all other parameters. The program itself can output all this either into code or at least in a "language" that is very easy to parse in game. My database program even contains the feature to duplicate records so I only have to edit those fields that are actually different.
The reason I took this trouble... Because I know this pain. Now it's still a lot of work, I gotta admit that, but at least it did in the end cut the time I needed in half, it it wasn't even cut into less time.
For enemies you meet in an RPG I also often whip up a quick program that allows me to quickly enter all stats and abilities and link for alternate strategies certain enemies can use against you (so I only have to code those).
Of course, that's my working style, and for me it works.
