How to Convert JSON to FBX?
Follow this beginner-friendly step-by-step guide to convert JSON to FBX accurately and efficiently using our dedicated conversion tool:
📥 Download and Install
Download and install Autoconverter on your system. This application will let you to convert your JSON files to FBX format - no additional CAD software required.
📂 Open Your JSON File
Go to File > Open… to load your JSON file (*.json, *.cityjson), or drag and drop it directly into the application window. The model loads into the 3D viewport for inspection before converting.
💾 Save As FBX Format
Go to File > Save As…, select FBX (*.fbx) as the output format, choose your destination folder and filename, then click Save to complete the JSON to FBX conversion.
3D City Model (CityJSON) File
The CityJSON file format is a modern, JSON-based (JavaScript Object Notation) standard designed for storing and exchanging 3D city models. It efficiently encodes buildings, roads, bridges, urban furniture, and other city objects, offering strong support for textures, semantics, and detailed metadata. CityJSON is a lightweight alternative to CityGML, optimized for simplicity, web integration, and high-performance applications.
Key Features of CityJSON Files
- JSON Simplicity: CityJSON files are lightweight, human-readable, and easily parsed by common programming languages, avoiding the complexity of XML structures like in CityGML.
- Semantic Data: Preserves rich metadata, including building heights, roof shapes, material classifications, and road types, enhancing 3D GIS and urban analysis.
- LOD (Level of Detail) Support: Manages multiple levels of detail (LOD1 through LOD4) to suit diverse visualization, simulation, and analysis needs.
- Web-Friendly Format: Perfect for 3D web visualization and integration with JavaScript libraries like Cesium and Three.js.
- Open and Extensible: Developed by the 3D Geoinformation Group (Delft University of Technology), CityJSON is an open standard that promotes interoperability and innovation.
- File Extension Note: Both CityJSON and GeoJSON use the .json extension - ensure you verify the file structure before processing to avoid errors.

Filmbox (FBX) 3D Model File Format
The FBX file format is a proprietary, industry-standard format for 3D models, assets, and animations. Originally developed by Kaydara and later acquired by Autodesk, FBX has become a universal 3D interchange format. It enables seamless transfer of 3D data - including complex hierarchies, materials, textures, and animations - between modeling, animation, and rendering software, ensuring consistent and efficient 3D workflows.
Key Features of FBX Files
- Embedded Textures: FBX files store texture images directly within the 3D file, eliminating the need for external assets and ensuring consistent model appearance across different platforms and applications.
- Reusable Geometry Components: FBX supports modular storage of geometry components, enhancing model consistency, reusability, and efficiency.
- Hierarchical Assembly Structures: The format captures complex assembly structures and object hierarchies, enabling detailed and organized 3D scenes.
- Animation Support: FBX files can embed animation data - including skeletons, keyframes, and motion capture - making them ideal for game development, film production, and AR/VR applications (though animation support may vary between software).
