Frequently asked questions

What JSON shape is expected?+

An array of flat objects works best — keys become the column headers and each object becomes a row. A single object is exported as one row.

Is the output a real Excel file?+

Yes. It is a genuine .xlsx workbook that opens natively in Excel, Google Sheets and Apple Numbers.

Are my files uploaded?+

No. The conversion runs entirely in your browser on your device — your JSON is never uploaded.
