Frequently asked questions

Does this support nested JSON objects?
Yes. Each nested object becomes a separate named struct in both Go and Rust output.
How are JSON number types mapped?
Integers map to int64 (Go) or i64 (Rust). Floats map to float64 (Go) or f64 (Rust). Detection is based on whether the value has a decimal point.
Is my data sent to a server?
No. All conversion runs entirely in your browser using JavaScript. Your JSON never leaves your device.
