I have created a PDF from an Excel spreadsheet.
All the cells on one column on the spreadsheet have links to data on a
website. The links are not transferred to the PDF file.

I know how to place the links on the PDF file:
Tools Advanced Editing LinkTool
Then open up a rectangle on the required cells in the PDF and place the link.
BUT, if I make changes to the spreadsheet, then I have to re-create all the
links again in the new PDF file.

What is the procedure to place the links in the cells of the spreasheet such
that they are active in the generated PDF file from the spreadsheet?

Thanks
Erich
