Another way to use VLOOKUP to streamline your work is to look up data from different sources, such as other worksheets or workbooks. To do this, you need to include the name of the worksheet or workbook in the table_array argument. For example, you can use this formula to look up the salary of an employee from a workbook named "Payroll.xlsx" and a worksheet named "Salaries": =VLOOKUP("Smith",'[Payroll.xlsx]Salaries'!A2:B10,2,FALSE) You can also use named ranges to refer to the table_array more easily. For example, you can name the range A2:B10 in the "Salaries" worksheet as "SalaryTable" and use this formula to look up the salary of an employee: =VLOOKUP("Smith",SalaryTable,2,FALSE) To use VLOOKUP with different sources, you need to make sure that the sources are open and accessible, that the lookup_value is in the same format and case as in the sources, and that the col_index_num is valid for the sources.
