       1001    3
       2344             


        

Answer 1

Here is a solution to get a list of unique items from your tables

There is two parts to this solution.

Part 1) Unique Count

{=SUM(IF(FREQUENCY(IF($A$2:$A$10<>"",MATCH($A$2:$A$10,$A$2:$A$10,0)),ROW($A$2:$A$10)-ROW($A$2)+1),1))}

This will count the number of unique items in your data table and will ignore any blanks

*Note this is an array formula and you will need to use "Ctrl" + "Shift" + "Enter" to use

Part 2) Unique List

This formula will give you the list of unique items in your table

={IF(ROWS($E$5:E5)>$E$2,"",INDEX($A$2:$A$10,SMALL(IF(FREQUENCY(IF($A$2:$A$10<>"",MATCH($A$2:$A$10,$A$2:$A$10,0)),ROW($A$2:$A$10)-ROW($A$2)+1),ROW($A$2:$A$10)-ROW($A$2)+1),ROWS($E$5:E5))))}

again this is an array formula. You can then drag this formula down to get all the unique items.

This formula is a dynamic formula, meaning you can set the data range past your current data range and the list will update as you enter new values.
