So type say "Unique items from the table" in A1 and enter the following formula as an array into A2 and copy it down as far as necessary.(it is supposed column A to be free) =INDEX(tbl,MIN(IF(COUNTIF($A$1:A1,tbl)=0,ROW(tbl)-MIN(ROW(tbl)) +1)),MATCH(0,COUNTIF($A$1:A1,INDEX(tbl,MIN(IF(COUNTIF($A$1:A1,tbl)=0,ROW(tbl)-MIN (ROW(tbl))+1)),,1)),0),1) A slightly different approach to extract unique items from a N*M table (named as "tbl" in the formula).
