RE: Number formating (format-number) and string to num

string to num
As far as I can see, Excel expects to see numeric cells formatted something
like this:

<Cell ss:StyleID="s50"><Data

I suspect you are trying to format the number in the way it appears on the
screen when Excel displays the spreadsheet. That's determined by format and
style information, not by the number itself. To generate the number, I think
the standard XSLT number-to-string conversion will almost certainly work
fine. I've no idea how you generate style information in the XML, but
looking at XML output by Excel will give you some clues. If all else fails,
there's probably some documentation somewhere.
