A tool for working with structured data: parsing, format conversion, and TypeScript type generation.
- JSON → TypeScript types — Generate TypeScript interfaces and types from JSON (and other formats).
- YAML support — Parse and serialize YAML alongside JSON and XML.
- Cross-format conversion — Convert between JSON, XML, YAML, etc. (e.g. JSON → XML, JSON → YAML, XML → JSON).
| Feature | Status |
|---|---|
| JSON parsing | ✅ Done |
| XML parsing | ✅ Done |
| YAML parsing | ✅ Basic (JSON-like subset) |
| TypeScript type generation from JSON/XML | ✅ Done |
| Serialization (JSON → XML, JSON → YAML, XML → JSON, etc.) | 🔲 Planned |
JSON, XML, and YAML (basic) parsers are implemented. The web UI lets you paste raw data, auto-detects the format, and shows the parsed result as JSON.
