Spreadsheet: advanced and superb (9)
I believe the answer is:
excellent
'superb' is the definition.
(thesaurus)
'spreadsheet advanced' is the wordplay.
'spreadsheet' becomes 'Excel' (Microsoft Excel is spreadsheet software).
'advanced' becomes 'lent' (advance can mean to lend).
'excel'+'lent'='EXCELLENT'
'and' is the link.
(Other definitions for excellent that I've seen before include "Admirable, first-rate" , "Outstanding, very good" , "magic" , "First-class" , "Fine" .)
