使用方法
- Paste a JSON object into the left panel。
- Set the root interface name and choose interface or type alias。
- Toggle readonly or null-to-optional as needed。
- Copy the generated TypeScript definitions from the right panel — conversion runs entirely in your browser。
範例
- Pasting {"id":1,"tags":["dev"],"address":{"city":"Seoul"}} with root name Root produces a Root interface with nested Address interface inferred automatically。
- Enabling "null → optional" changes fields whose value is null from `field: null` to `field?: unknown`。
