## Extract a unique distinct list sorted from A-Z from range

The image above shows an array formula in cell B8 that extracts unique distinct values sorted alphabetically from cell range B2:E5.

**Array formula in B8:**

Copy cell B8 and paste it to cells below as far as necessary.

To enter an array formula, type the formula in a cell then press and hold CTRL + SHIFT simultaneously, now press Enter once. Release all keys.

The formula bar now shows the formula with a beginning and ending curly bracket telling you that you entered the formula successfully. Don't enter the curly brackets yourself.

### Explaining formula in cell B11

This formula consists of two parts, one extracts the row number and the other the column number needed to return the correct value.

INDEX(*reference*, *row*, *col*)

Step 1 to 6 shows how the row number is calculated, step 7 to 11 demonstrates how to calculate the column number.

#### Step 1 - Prevent duplicates

The COUNTIF function counts values based on a condition or criteria, in this case, we take into account previously displayed values in order to prevent duplicates in our output list.

COUNTIF($B$7:B7, $B$2:$E$5)=0

becomes

COUNTIF("Unique distinct", {"Banana", "Raspberry", "Banana", "Raspberry";"Grapefruit", "Banana", "Apple", "Grapefruit";"Blueberry", "Kiwifruit", "Raspberry", "Blackberry";"Raspberry", "Blueberry", "Blueberry", "Banana"})

becomes

{0,0,0,0;0,0,0,0;0,0,0,0;0,0,0,0}=0

and returns

{TRUE, TRUE, TRUE, TRUE;TRUE, TRUE, TRUE, TRUE;TRUE, TRUE, TRUE, TRUE;TRUE, TRUE, TRUE, TRUE}.

#### Step 2 - Replace TRUE with the corresponding rank order

The following IF function returns the corresponding sort order if the list had been sorted from A to Z based on the logical expression. FALSE returns "" (nothing).

IF(COUNTIF($B$7:B7,$B$2:$E$5)=0,COUNTIF($B$2:$E$5,"<"&$B$2:$E$5)+1,"")

becomes

IF({TRUE, TRUE, TRUE, TRUE;TRUE, TRUE, TRUE, TRUE;TRUE, TRUE, TRUE, TRUE;TRUE, TRUE, TRUE, TRUE}, {1,12,1,12;9,1,0,9;6,11,12,5;12,6,6,1}+1,"")

becomes

IF({TRUE, TRUE, TRUE, TRUE;TRUE, TRUE, TRUE, TRUE;TRUE, TRUE, TRUE, TRUE;TRUE, TRUE, TRUE, TRUE}, {1,12,1,12;9,1,0,9;6,11,12,5;12,6,6,1}+1,"")

becomes

IF({TRUE, TRUE, TRUE, TRUE;TRUE, TRUE, TRUE, TRUE;TRUE, TRUE, TRUE, TRUE;TRUE, TRUE, TRUE, TRUE}, {2,13,2,13;10,2,1,10;7,12,13,6;13,7,7,2},"")

and returns

{2,13,2,13;10,2,1,10;7,12,13,6;13,7,7,2}

#### Step 3 - Extract smallest value in array

The SMALL function extracts the k-th small number in array, in this case the second argument (k) is 1.

SMALL(IF(COUNTIF($B$7:B7, $B$2:$E$5)=0, COUNTIF($B$2:$E$5, "<"&$B$2:$E$5)+1, ""), 1)

becomes

SMALL({2,13,2,13;10,2,1,10;7,12,13,6;13,7,7,2}, 1)

and returns 1.

#### Step 4 - Replace TRUE with the corresponding row number

The IF function uses a logical expression to determine which value (argument) to return.

IF(SMALL(IF(COUNTIF($B$7:B7,$B$2:$E$5)=0,COUNTIF($B$2:$E$5,"<"&$B$2:$E$5)+1,""),1)=COUNTIF($B$2:$E$5,"<"&$B$2:$E$5)+1,ROW($B$2:$E$5)-MIN(ROW($B$2:$E$5))+1)

becomes

IF(1=COUNTIF($B$2:$E$5, "<"&$B$2:$E$5)+1, ROW($B$2:$E$5)-MIN(ROW($B$2:$E$5))+1)

becomes

IF(1={2,13,2,13;10,2,1,10;7,12,13,6;13,7,7,2}, ROW($B$2:$E$5)-MIN(ROW($B$2:$E$5))+1)

becomes

IF({FALSE,FALSE,FALSE,FALSE;FALSE,FALSE,TRUE,FALSE;FALSE,FALSE,FALSE,FALSE;FALSE,FALSE,FALSE,FALSE}, ROW($B$2:$E$5)-MIN(ROW($B$2:$E$5))+1)

becomes

IF({FALSE,FALSE,FALSE,FALSE;FALSE,FALSE,TRUE,FALSE;FALSE,FALSE,FALSE,FALSE;FALSE,FALSE,FALSE,FALSE}, {1;2;3;4})

and returns

{FALSE,FALSE,FALSE,FALSE;FALSE,FALSE,2,FALSE;FALSE,FALSE,FALSE,FALSE;FALSE,FALSE,FALSE,FALSE}

#### Step 5 - Find smallest value

The SMALL function finds the smallest value in the array ignoring the boolean values

SMALL(IF(SMALL(IF(COUNTIF($B$7:B7,$B$2:$E$5)=0,COUNTIF($B$2:$E$5,"<"&$B$2:$E$5)+1,""),1)=COUNTIF($B$2:$E$5,"<"&$B$2:$E$5)+1,ROW($B$2:$E$5)-MIN(ROW($B$2:$E$5))+1),1)

becomes

SMALL({FALSE,FALSE,FALSE,FALSE;FALSE,FALSE,2,FALSE;FALSE,FALSE,FALSE,FALSE;FALSE,FALSE,FALSE,FALSE},1)

and returns 2. This is the row number we need to extract the correct value from cell range B2:E5.

#### Step 6 - Return array

This step uses the INDEX function to return an array from a given row in cell range B2:E5.

INDEX(COUNTIF($B$2:$E$5, "<"&$B$2:$E$5)+1, SMALL(IF(SMALL(IF(COUNTIF($B$7:B7, $B$2:$E$5)=0, COUNTIF($B$2:$E$5, "<"&$B$2:$E$5)+1, ""), 1)=COUNTIF($B$2:$E$5, "<"&$B$2:$E$5)+1, ROW($B$2:$E$5)-MIN(ROW($B$2:$E$5))+1), 1), , 1)

becomes

INDEX(COUNTIF($B$2:$E$5, "<"&$B$2:$E$5)+1, 2, , 1)

becomes

INDEX({2,13,2,13;10,2,1,10;7,12,13,6;13,7,7,2}, 2, , 1)

and returns

{10,2,1,10}

#### Step 7 - Match value in array

This step uses the MATCH function to return the correct column number needed to extract the value we need from cell range B2:E5.

MATCH(MIN(IF(COUNTIF($B$7:B7, $B$2:$E$5)>0, "", COUNTIF($B$2:$E$5, "<"&$B$2:$E$5)+1)), INDEX(COUNTIF($B$2:$E$5, "<"&$B$2:$E$5)+1, SMALL(IF(SMALL(IF(COUNTIF($B$7:B7, $B$2:$E$5)=0, COUNTIF($B$2:$E$5, "<"&$B$2:$E$5)+1, ""), 1)=COUNTIF($B$2:$E$5, "<"&$B$2:$E$5)+1, ROW($B$2:$E$5)-MIN(ROW($B$2:$E$5))+1), 1), , 1), 0)

becomes

MATCH(MIN(IF(COUNTIF($B$7:B7, $B$2:$E$5)>0, "", COUNTIF($B$2:$E$5, "<"&$B$2:$E$5)+1)), {10,2,1,10}, 0)

becomes

MATCH(1, {10,2,1,10}, 0)

and returns 3. This is the column number we need.

#### Step 8 - Return value

INDEX($B$2:$E$5, SMALL(IF(SMALL(IF(COUNTIF($B$7:B7, $B$2:$E$5)=0, COUNTIF($B$2:$E$5, "<"&$B$2:$E$5)+1, ""), 1)=COUNTIF($B$2:$E$5, "<"&$B$2:$E$5)+1, ROW($B$2:$E$5)-MIN(ROW($B$2:$E$5))+1), 1), MATCH(MIN(IF(COUNTIF($B$7:B7, $B$2:$E$5)>0, "", COUNTIF($B$2:$E$5, "<"&$B$2:$E$5)+1)), INDEX(COUNTIF($B$2:$E$5, "<"&$B$2:$E$5)+1, SMALL(IF(SMALL(IF(COUNTIF($B$7:B7, $B$2:$E$5)=0, COUNTIF($B$2:$E$5, "<"&$B$2:$E$5)+1, ""), 1)=COUNTIF($B$2:$E$5, "<"&$B$2:$E$5)+1, ROW($B$2:$E$5)-MIN(ROW($B$2:$E$5))+1), 1), , 1), 0), 1)

becomes

=INDEX($B$2:$E$5, 3, 2)

and returns "Apple" in cell B8.

This is exactly what I've been looking for... almost. It breaks if there are blank cells in the named range. Is there a way to get this to work if there are blanks in the range?

Thanks.

Dave,

Oscar,

I need to sort from largest value to smallest and continue to have issues. I'm working with values and have flipped SMALL to LARGE and Min to MAX. I must be missing something simple, could you please point me in the correct direction?.

Appreciate all the help.

Alex
