Mastering JSON to CSV Conversion
1 Deep Nested Support
Our tool automatically flattens multi-level nested objects. For example, {"user": {"name": "John"}} becomes a column named user.name. You can also choose to stringify nested objects if you prefer.
2 Batch Processing
Upload multiple JSON files at once. The tool will merge them into a single CSV if they share similar structures, or you can process them individually.
3 High Performance
Built with Web Workers, the conversion happens in a background thread. This keeps your browser responsive even when processing large files (up to 50MB).
4 Privacy First
Your data never leaves your computer. All processing is done locally in your browser, ensuring total privacy for sensitive data.
