Frequently Asked Questions

What is JSON to Rust Struct?
Generate Rust structs with serde Serialize and Deserialize derive macros from JSON data online for free. Proper Rust types from any JSON sample. No signup required.
Are comments preserved during conversion?
Comment handling depends on the source and target formats. Formats that support comments (like YAML and TOML) will have them parsed, but since most data interchange formats like JSON do not support comments, they may be stripped during conversion.
What happens with invalid input?
The tool validates your input before conversion and displays clear error messages if the data is malformed. This helps you identify and fix syntax issues before attempting the conversion.
Can I convert between nested formats?
Yes, deeply nested and complex data structures are fully supported. The converter preserves the hierarchy, arrays, and key-value pairs from your source format and maps them accurately into the target format.
Is JSON to Rust Struct free to use?
Yes, all format conversions are free and unlimited. No account is required, and the tool works entirely in your browser.
Is my data safe when using JSON to Rust Struct?
Yes, your data stays on your device. The conversion runs entirely in your browser, and no data is uploaded to any server.
