Preguntas frecuentes

Is my data uploaded to a server?

No. The conversion runs entirely in your browser with SheetJS, so your spreadsheet never leaves your device.

Does it keep multiple sheets?

When converting Excel to CSV, you can pick which sheet to export, since CSV holds a single table. CSV to Excel produces a workbook with one sheet.

Which Excel formats are supported?

Modern .xlsx files and older .xls files can be read. Output is always the modern .xlsx format.
