Sorry, but the above instructions were for an MS Access query grid.
Using MS Query in Excel the SQL would be along the lines of:
SELECT RANGENAME.PersonName & ',' AS PersonName
FROM `C:\WORKBOOKNAME`.WORKSHEETNAME RANGENAME
WHERE RANGENAME.PersonName Like 'ROB%'
or
SELECT RANGENAME.PersonName & ',' AS PersonName
FROM `C:\WORKBOOKNAME`.WORKSHEETNAME RANGENAME
WHERE RANGENAME.PersonName & ',' Like 'ROB%,'
