Our tool intelligently handles nested JSON objects by flattening them with dot notation (e.g., 'user.address.city'). Arrays are converted to comma-separated values within cells.

For deeply nested structures, the converter automatically creates columns for all paths, ensuring no data is lost during conversion. This makes it perfect for complex API responses and multi-level data structures.

All JSON processing happens entirely in your browser using JavaScript. Your data never leaves your device, and we don't store, view, or have access to any content you convert.

This makes our tool perfect for sensitive data like customer information, financial records, API credentials, or confidential business data that cannot be uploaded to external servers.
