Usage

Features

Based on quicktype engine, this tool automatically converts JSON data to Rust serde struct definitions with type inference and Option type auto-detection.

Steps

Enter or paste JSON data in the left text box, set the root type name, adjust field visibility and code density. Rust code will be generated in real time.

Options

Field visibility: controls struct field visibility modifiers - private (default), crate, or public.
Code density: standard mode writes fields on separate lines; dense mode compresses into tighter layout.
Derive Debug/Clone/PartialEq: adds derive macros for the corresponding traits.
Skip None serialization: skips Option fields with None values during serialization.

Notes

Requires serde dependency in Cargo.toml. Numbers inferred as i64 or f64. null fields become Option type.
