Questions

What happens to dates?

A cell in the standard short date format of Excel is written as 2026-09-17. A cell with a custom date format is written the way that format displays it.

Do formulas survive?

Their results do. CSV has no formulas.

Can I pick one sheet by name?

Choose all sheets; each becomes a file named after the sheet, and you keep the one you need.

Is the file uploaded?

No.
