The hyperlink function allows you to create a working link with a formula. It takes two arguments: link_location and, optionally, friendly_name.
Working from the inside out, VLOOKUP looks up and retrieves a link value from column 2 of the named range "link_table" (B5:C8). The lookup value comes from column E, and VLOOKUP is configured for exact match.
