Convert JSON to STEP File

JSON to STEP ......

Provided below is a list of supplementary resources focusing on the interoperability and exchange between JSON and STEP files. Utilize these to streamline the JSON to STEP file conversion.


JSON (CityJSON) is an optimized version of the CityGML OGC (Open Geospatial Consortium) file format, designed for the efficient storage and exchange of 3D city models and landscapes. The CityJSON file format supports city object names, nested hierarchy, reusable geometry component instances, and custom materials with texture images. Our Autoconverter JSON file converter facilitates seamless reading and writing of CityJSON JSON geometries with custom attributes. It also allows for smooth conversion between other common 3D mesh file formats.


The STEP (STandardized Exchange of Product) file format is extensively used for the exchange of 3D data across various computer systems, including CAD, CAM, and CAE. As STEP geometry data is stored in a text-based format, exporting triangular meshes with thousands or even millions of faces using Autoconverter software may lead to larger file sizes. However, if your geometry defines a manifold solid, our software will strive to create an optimized faceted BREP representation, potentially reducing the STEP file size by up to one-third. It’s crucial to note that while the STEP file format supports colors per assembly, it lacks an alpha component. Consequently, any transparency settings will not be retained in the final STEP file.
