The following table was used by a personnel department to lookup the salary of an employee. The employee can be entered as a Name or as a Numeric value. The =ISNUMBER() function has been used to identify the type of entry made, and then the =IF() decides which VLOOKUP to perform.
|Type Employee Name or ID :||eric|
|The Salary is :||#######|
|=IF(ISNUMBER(E35), VLOOKUP(E35,C29:E33,3, FALSE), VLOOKUP(E35,D29:E33,2, FALSE))|
