Frequently asked questions
- What JSON formats are accepted?
- You can paste a JSON array of objects (e.g., [{"name": "Alice", "age": 30}]) or a single JSON object. The keys become column headers in the Excel file.
- Can I also download as CSV?
- Yes. After parsing your JSON, you can download the data as either XLSX or CSV using the buttons below the preview table.
- Is my data uploaded anywhere?
- No. All processing happens locally in your browser using the SheetJS library. Your data never leaves your device.
