You can actually do this and have Excel show a clickable link. Use this format in the CSV file:
=HYPERLINK("URL")
So the CSV would look like:
1,23.4,=HYPERLINK("http://www.google.com")
However, I’m trying to get some links with commas in them to work properly and it doesn’t look like there’s a way to escape them and still have Excel make the link clickable.
Does anyone know how?
