Why convert VSJ to VSB?
A lone .vsj breaks if its model files move, while a .vsb carries everything in one archive. Converting means letting ViewSTL gather the referenced STL meshes and pack them with the scene JSON into one Zip.
About these formats
.VSJ
ViewSTL JSON Model
A .vsj file is a ViewStl JSON scene file created by the ViewSTL online 3D viewer and its JavaScript plugin. It stores the state of a 3D scene as plain-text JSON, including canvas and…

Virtual Sampler Bank
A .VSB file is associated with Virtual Sampler Bank, a audio file.

- The conversion only works if the STL models the VSJ references are available, because the VSB must embed them.
- A
.vsbis larger than the.vsjsince it now carries the full model geometry, not just references. - The scene itself is unchanged - VSB simply wraps the same VSJ plus the models into one portable Zip.
Frequently asked questions
What's the difference between VSJ and VSB?
VSJ is just the JSON scene status; VSB is a Zip that adds the actual STL models so the scene is self-contained.
Why convert VSJ to VSB?
So the scene travels as a single file - a VSJ breaks if its referenced models are missing, while a VSB embeds them.
Do I need the original models?
Yes. ViewSTL has to load the referenced STL models to pack them into the VSB.
Can I open a VSB without ViewSTL?
You can rename it to
.zip and extract the .vsj and STL files, but ViewSTL is what actually renders it.
