Link single word to a Website

[golfertel]

How do I link a single word in table/excel to a Website. At the moment trying to link a word ends up with the whole page ling to the site. Any ideas please.
It is an hour later, I have now found that pasted excel sheet "words" will not link. Putting in a separate word outside the sheet will link however it would still be nice to link a word within the sheet, any ideas please.
