Frequently asked questions

What happens to multiple sheets?

CSV holds a single table, so the first sheet is exported and the tool tells you when others were left out. Convert each sheet separately if you need them all.

Are dates preserved?

Dates are written as the text your spreadsheet displays, which avoids the classic problem of them arriving as raw serial numbers.
