Good to know
Which spreadsheet files can I choose?
The spreadsheet tools accept XLSX, XLS, ODS, CSV and TSV. JSON to Excel expects a JSON array of objects, with one object per row.
How do I choose a worksheet?
Where a sheet-name option is shown, leave it empty for the first sheet, enter a sheet name, or enter * for all sheets. Multiple output files may be packed into a ZIP.
Are formulas and formatting preserved?
CSV, JSON and other table formats do not preserve a complete workbook. They export cell values and structure supported by the chosen format. Check formulas, dates and formatting in the downloaded file before replacing the original.
