Can this tool handle nested JSON?

Yes, the converter supports nested JSON objects. You can choose to flatten nested structures into separate columns with dot notation (e.g., user.name, user.email).

Is my JSON data secure?

Absolutely. All conversion happens entirely in your browser. Your JSON data never leaves your device.

What Excel format is generated?

The tool generates .xlsx files (Excel 2007+), which are compatible with Microsoft Excel, Google Sheets, LibreOffice Calc, and other spreadsheet applications.
