Please Note: This article is written for users of the following Microsoft Excel versions: 97, 2000, 2002, and 2003. If you are using a later version (Excel 2007 or later), this tip may not work for you. For a version of this tip written specifically for later versions of Excel, click here: Special Characters In Hyperlinks.
As you learn in other issues of ExcelTips, Excel allows you to create hyperlinks to other Excel workbooks. If you create a workbook that uses the pound sign (#) in the file name, Excel has no problem with that. It will have a problem, however, if you try to create a hyperlink that references that workbook.
The reason for this is because the pound sign is a valid character for a file name, but it is not a valid character for use in a hyperlink. Since hyperlinks are closely related to URLs, you may think that replacing the pound sign with its hexadecimal equivalent (%23) in the hyperlink might do the trick. For instance, you might use the name My%23File.xls in the hyperlink instead of My#File.xls. This potential solution won't work, however. Excel still complains that it cannot find the file when you click on the hyperlink.
According to Microsoft sources, there are only two potential solutions. The first is to rename the target workbook so it doesn't include the pound sign in the file name. If this is not possible, then the second solution is to create a hyperlink by pasting instead of by using the Insert Hyperlink command. Follow these steps:
Your hyperlink appears, complete with the pound sign, and it will work.

That's correct for your browser but Excel will ignore the pound sign and truncate the hyperlink from there. So your hyperlink is executed as it where simply www.somewebsite.com/myPDF.pdf without #page=2 .

The pound sign is a valid character for a hyperlink, for example, "www.somewebsite.com/myPDF.pdf#page=2"

Excel does work with the # sign when it is in the target but not when in the relative link. Extremely buggy behaviour. And don't get me started about folder-path length...
so =hyperlink("\blah#blahmeh","blah") won't work BUT =hyperlink("..meh","blah") will if the excel doc is in a different child folder to meh and even if the target root folder is \blah#blah - Tested
or =hyperlink(".","blah") may work if in same folder - Not Tested
Relative works, absolute does not. I suspect it occurs when excel pastes the string together in the backend wmi processes using win3.1 code.

I consider this a bug in Office. The %xx encoding was specifically designed to avoid this kind of issue. MS goofed here; the %23 should work.
This is more of a problem for me because I'm creating links to files other than Excel workbooks. Their "Paste as" workaround doesn't work for other file types.

Got a version of Excel that uses the menu interface (Excel 97, Excel 2000, Excel 2002, or Excel 2003)? This site is for you! If you use a later version of Excel, visit our ExcelTips site focusing on the ribbon interface.
