Not knowing exactly what you have in those cells, expect they are
complete email addresses, what version of Excel, and your options
would suggest the following:
If you have Excel 2002 (Excel XL) or higher:
you can suppress hyperlink generation under the Auto Correct from the Tools menu.
Tools (menu), Autocorrect Options, Autoformat as you type (Tab).
so you want to do the opposite.
Next just in case the email addresses have spaces I would try the TRIMALL macro

it might just recreate the hyperlinks since it will reenter the cells in your selection.
Essentially in addition to trimming text cells it will act like F2 then Enter
To generate hyperlinks in each cell based on the current value when run
Creating Hyperlinks for all Cells in a Selection (#MakeHyperlinks)

And just to help other that might want to remove current hyperlinks (full circle)
