The Future of JSON Engineering
In the modern era of web development, JSON (JavaScript Object Notation) has become the de-facto standard for data exchange. However, working with complex JSON structures can often be cumbersome. JSONGen was engineered to bridge the gap between raw data and developer productivity.

Our tools run entirely in your browser. Your sensitive data never leaves your machine, ensuring 100% privacy and compliance with data security standards like GDPR and HIPAA at the source.
High-Performance Engine
Optimized V8-level algorithms handle massive JSON files without freezing your browser. Experience near-instant processing even with multi-megabyte datasets that crash other online formatters.
Input Data
Paste your raw JSON, XML, or YAML into our high-performance editors.
Instant Engine
Our local processing engine applies transformations in microseconds.
Deploy Ready
Copy the optimized output directly into your production environment.
Frequently Asked Questions

Can I use this for commercial projects?
Absolutely. JSONGen is free for both personal and commercial use without any restrictive licensing.
What is the file size limit?
There is no hard limit on our end. It depends on your browser's memory capacity. We've tested up to 50MB files successfully.
