JSON to Rust Struct Generator (Serde)
Generate Rust structs with Serde derives from JSON. Field names follow Rust conventions and are mapped back to the original keys automatically.
How it works
- 1
Paste or open your data
Paste text, drop a file onto the editor or click Open file. Load sample shows how the tool works.
- 2
Adjust the options
The result updates as you type. Change the options to get exactly the output you need.
- 3
Copy or download
Copy the result to the clipboard or download it as a file.
Why PixNudge
Nothing is uploaded
Your data is processed in your browser and never sent to a server, so API keys, tokens and customer data stay private.
Instant, even for large files
There is no round trip to a server: results appear as you type, and files of several megabytes are handled smoothly.
Exact numbers
Long numbers such as 64-bit IDs are kept exactly as written instead of being rounded.
Frequently asked questions
Which crates do I need?
serde with the derive feature, and serde_json. The structs derive Serialize and Deserialize, as well as Debug and Clone.
How are field names converted?
Keys become snake_case field names, and a #[serde(rename_all = ...)] attribute maps them back to the original JSON keys, so isActive becomes is_active.
How are optional fields typed?
Keys that are missing from some items or can be null become Option<T>.
