Frequently asked
Does every chunk keep the header row? +
Yes. The first row of the first sheet is the header, and it gets copied onto the top of every workbook. Each chunk stands on its own.
Does it handle multi-sheet workbooks? +
It splits the first sheet only. If your workbook has several sheets, save the one you want as its own file first, then split that.
