Download SolidWorks (.sldprt) file with selected configuration as .stl file?

With GrabCad Workbench, I can download SolidWorks (.sldprt) file as .stl file. However, with SolidWorks file containing multiple configurations, I can only download default configuration. How can I download each configuration in SolidWorks file as .stl file? Is there any free online solution, something is similar to GrabCad Workbench?

I don't understand the quastion

.STL file is a binary file, only file from which you can create for 3d printing.
.Sldprt is part model which is a tree of task features list of model creation
