To filter data to extract matching values in two lists, you can use the FILTER function and the COUNTIF or COUNTIFS function. In the example shown, the formula in F5 is: =FILTER(list1,COUNTIF(list2,list1)) where list1 (B5:B16) and list2 (D5:D14) are named ranges. The result returned by FILTER includes only the values in list1 that appear in list2. Note: FILTER is a new dynamic array function in Excel 365.
