Or just write your own custom extractor, which is a lot easier than it sounds.
VB has some nice string functionality that translates nicely into working with tables.
I can't program.

The only reason that Romjuice won't work is that the game uses a variable, so to speak, to change from hiragana to katakana. Use a code, and everything changes to katakana. Use it again, and it goes back to hiragana. But by default, the text begins as hiragana, so if a string ends in katakana the engine reboots the variable back into hiragana mode.
Romjuice can handle table swapping, but not when it acts like this.
