You could try https://www.plogue.com/products/sforzando/ which is free and should convert sf2 to sfz.
I already recommended it in another thread, he's not interested.
When you drop an SF2 file in SForzando it converts it to SFZ. For some reason he doesn't want this.
From that thread:
joden Shouldn't have to convert to sfz files and most convertors do a poor job anyway
However I was under the impression, the only thing that is converted is a text file, not the actual sample.
So that makes no sense to me.
