About JSON Machine
JSON Machine is a high-performance, developer-first productivity tool designed to simplify the way you
interact with JSON data and schemas. What started as a simple visualizer has evolved into a
comprehensive Round-Trip Editor that bridges the gap between raw code and visual
design.
The Round-Trip Advantage
Most JSON tools force you to choose between a text editor and a visual builder. JSON Machine is designed
for a seamless flow:
- Full Import Fidelity: Paste existing JSON and watch it instantly transform into a
visual tree, preserving all your actual data values.
- Preserved Values: Unlike generic schema builders, we handle strings, numbers, and
booleans as first-class citizens, ensuring your data remains intact throughout the editing process.
- Deep Nesting Support: Easily manage complex, deeply nested objects and multi-item
arrays with responsive drag-and-drop interactions.
- JSON Schema Generation: Automatically generate valid Draft-07 JSON Schemas to
document your data structures.
Key Features
- Visual CRUD: Add, move, edit, and delete fields using an intuitive canvas.
- Smart JSON Repair: Our built-in repair engine automatically fixes broken syntax,
trailing commas, and unbalanced brackets during import.
- Empty Values Mode: Convert data-heavy JSON into structure-only templates with one
click.
- Instant Previews: Real-time synchronization between the builder, the generated
JSON, and the schema.
Privacy by Design
We understand that your data is sensitive. JSON Machine runs entirely locally in your
browser. No data is ever sent to our servers. Your imports, edits, and exports stay on your machine,
ensuring 100% privacy and security.
Built for Developers
Whether you're designing API responses, prototyping application state, or documenting data structures,
JSON Machine provides the precision of a code editor with the speed of a visual tool.
