Convert STEP assembly in to separate STEP files without CAD

Dear all,

is there a way to convert a STEP assembly in to separate STEP files without CAD? I'm using Creo Parametric my self. Some of my colleagues use the CREO viewer and they often ask me to convert STEP assemblies in to separate STEP parts which can be send to suppliers. So I'm looking for an alternative :-)

Is there a "standalone" tool or CAD viewer or another solutions for this?

Thx
