JSON to Rust Serde
Generate Rust structs or a Root alias with Serde serialization and deserialization. Shortened unique field names preserve original keys through serde rename attributes or explicit map lookups for long keys; mixed arrays and null use serde_json::Value.
About this json to rust serde
Generate Rust structs or a Root alias with Serde serialization and deserialization. Shortened unique field names preserve original keys through serde rename attributes or explicit map lookups for long keys; mixed arrays and null use serde_json::Value Transforms and validates developer data structures locally, preventing confidential payload exposure during data wrangling.
Syntax parsing & data transformation logic
Performs semantic analysis on dynamic structured data (JSON, YAML) to synthesize statically typed code definitions across TypeScript (interfaces, types), Zod (runtime validation schemas), Python (Pydantic v2 BaseModels, Dataclasses), Go (structs with json tags), and Rust (serde structs). The type inference engine scans array elements to infer union types, detects optional fields by comparing presence across multiple objects, resolves snake_case/camelCase identifier mappings, and normalizes reserved keyword conflicts.
Worked conversion & output example
Scenario: Rust Serde: Generate a model for the displayed object and retain every original property.
Sample input:
Processing: Infer types from the JSON sample and emit Rust Serde source code. This page does not run the target compiler or library; validate the generated code and sample in your own target environment.
Illustrative output:
Syntax constraints & input size limits
Accepts JSON text up to 1,000,000 UTF-16 code units and 100 nesting levels; output is limited to 8,388,608 code units. Invalid syntax, duplicate keys, invalid Unicode, unsafe integer values, overflow, underflow and decimal precision loss are rejected. Quote exact large numbers as strings. Dates remain strings. Inference describes the supplied sample, not every possible API response. Enable serde’s derive feature and add serde_json. Deserialize into Root with serde_json::from_str. Integer tokens use i64; decimal or exponent tokens use f64. Empty arrays, mixed arrays and null use generic JSON values where needed, so those positions are not constrained to the sample shape. Structs reject unknown fields. JSON keys longer than 512 UTF-16 code units use explicit typed Serialize and Deserialize implementations to avoid excessive compiler memory.
Data conversions and formatting in JSON to Rust Serde reflect standard structured syntax. Verify parsed outputs against your target runtime before deployment.
Local client execution boundary
Data parsing and transformations in JSON to Rust Serde execute in the local browser tab without remote data transmission.

How to use it
- Paste one complete JSON value or load the sample.
- Run locally to generate code, then copy the complete result.
- Compile or validate the code in your target project and review inferred types before use.
Frequently asked questions
What Rust Serde code is generated for id, name, and active?+
The browser emits a Root struct with `#[derive(Debug, Serialize, Deserialize)]`, `#[serde(deny_unknown_fields)]`, and renamed public fields: id is i64, name is String, and active is bool.
How does the Rust generator keep original JSON property names?+
Each emitted field receives `#[serde(rename = "...")]`. Rust identifiers are made safe while deserialization still expects the original JSON property spelling.
Does generated Rust define the whole data contract?+
No. Types are inferred from the supplied JSON sample. A heterogeneous or later-added field can need a different representation, so compile and review generated code with real contract cases.
Does JSON to Rust Serde compile Cargo or upload my sample?+
It emits Rust source text in the browser; it does not invoke Cargo, run a compiler, or send the JSON to a code-generation API. Ordinary page-resource requests are separate.
