Errrr, the function is the link. There's no such thing as a clickable link without that function. (Consider this: which value would you expect when pasting something that is both a clickable link and a title? C2 or A2?)
You could replace the function with just C2. After that, using Paste Values will give you a non-clickable link. (But: you would already have that very same non-clickable link in C2 itself, so in the end that's useless.)
Or, if you expect some HTML magic: use something like the following, which is not clickable in Excel, but may be helpful when you use the result elsewhere:
= "<a href='" & C2 & "'>" & A2 & "</a>"
(Where &
is the short notation for function CONCATENATE.)
