Is every sheet exported?

Only the first sheet, with a note telling you the sheet name if there is more than one.

Yes, to YYYY-MM-DD, or YYYY-MM-DD HH:MM:SS when a time is present.

What about currency formatting?

Numbers use their underlying value without currency symbols or thousands separators.

Can I export CSV instead?

Yes. Switch to the CSV tab, or open the Excel to CSV page.

Excel to Markdown table

Drop an .xlsx file and the first sheet becomes a Markdown table ready for a README or a wiki. Dates come through as YYYY-MM-DD, calculated formula values are used, and cells with leading zeros keep them.

Excel parsing runs locally in a Web Worker, so a large workbook does not lock up the page and the file is never transmitted.
