Since this question was asked nine days ago, you probably aren't going to
get a real useful answer here, but I did a Google search on: excel.to.pdf hyperlinks
The periods join words together could have used: "excel to pdf" hyperlinks
There are lots of packages to convert to PDF, and since it looks like many
of them appear to include hyperlinks that in itself might not be the problem.
There are object hyperlinks, where you include a hyperlink Ctrl+K,
and there are HYPERLINK Worksheet Functions. I would not expect
you to have much luck with a Worksheet Function in a conversion.
Consider what you are hyperlinking to, is it
1) A complete link to a web page -- this should be the easiest
and most straight forward.
2) A link to cell in another workbook, or to a worksheet including the
the same worksheet could present lots of problems (IMO).
You might have to save as HTML and then convert the HTML to PDF.
