Frequently Asked Questions
Does the Excel file support formatting? ▼
The generated XLSX file contains the data in a clean spreadsheet. Advanced formatting like merged cells or formulas are not added - just the raw data ready to open in Excel or Google Sheets.
Is my data sent to a server? ▼
No. The conversion uses SheetJS entirely in your browser.
