Two data converters tools, side-by-side. See which fits your task.
Data Converters
Generate Kotlin data classes from JSON. Handles nested objects, arrays, and nullable fields.
Open JSON to KotlinYour specific task is generate kotlin data classes from json. Open the page, drop your input, get the result — typically under a second.
Your goal is generate rust structs with serde attributes from json. Same approach: paste in, get the result, move on. No account, no upload.
Both tools live in the same category, so the choice depends on the exact subtask. JSON to Kotlin focuses on generate kotlin data classes from json; JSON to Rust focuses on generate rust structs with serde attributes from json. Try whichever description matches your goal more closely — they're both free.
Yes — both tools are free for unlimited personal use. The Pro plan unlocks higher limits and batch features but the core functionality stays free forever.
Absolutely. Many users chain multiple tools together — process a file with one, then feed the result into another. Nothing is uploaded, so chaining is essentially instant.
No. Both JSON to Kotlin and JSON to Rust work without signup. We only ask for an email if you decide to subscribe to a paid plan.
