Steps
- Paste or upload JSON - Use an array of objects for the cleanest spreadsheet output.
- Review flattened fields - Nested object keys become column names using dot notation.
- Preview rows - Check the first rows before creating the workbook.
- Download XLSX - Save the generated Excel file locally.
Before You Start
- Arrays become rows and object keys become column headers.
- Nested arrays are preserved as JSON strings inside cells.
- Invalid JSON must be fixed before conversion can run.
