About This Tool

Paste any JSON array of objects and convert it to a well-structured Excel file instantly. The tool automatically detects all keys across all objects and uses them as column headers, ensuring no data is missed even when objects have different fields. A built-in preview lets you verify the table structure before downloading. Supports deeply nested value flattening and handles null or undefined values gracefully. Ideal for developers, data analysts, and anyone who needs to share JSON data in spreadsheet format. The generated .xlsx file opens in Excel, Google Sheets, and LibreOffice Calc.
