That's it. As I remember it, there's one included in one of the later patches that's not in the Forge Tools, but none for Entrenchment.
The convertdata.exe for entrenchment and the original sins of a solar empire is always (as far as im aware, it is for the most recent builds of sins atleast) included in the Sins directory, by default: C:\Program Files\Stardock Games\Sins of a Solar Empire (on XP).
