Explaining array formula in cell D3
Step 1 - Remove duplicates
=INDEX(List, MATCH(LARGE(IF(COUNTIF($D$2:D2, List)=0, COUNTIF(List, List), ""), 1), COUNTIF(List, List)*(COUNTIF($D$2:D2, List)=0), 0))
IF(COUNTIF($D$2:D2, List)=0, COUNTIF(List, List), "")
becomes
IF(COUNTIF("List sorted by occurrances", {"DD";"AA";"AA";"BB";"AA"; "DD";"EE";"AA";"BB";"EE";"CC";"EE"})=0, COUNTIF({"DD";"AA";"AA";"BB";"AA"; "DD";"EE";"AA";"BB";"EE";"CC";"EE"}, {"DD";"AA";"AA";"BB";"AA"; "DD";"EE";"AA";"BB";"EE";"CC";"EE"}), "")
becomes
IF({0;0;0;0;0;0;0;0;0;0;0;0}=0, {2;4;4;2;4;2;3;4;2;3;1;3}, "")
becomes
IF({TRUE;TRUE;TRUE;TRUE;TRUE; TRUE;TRUE;TRUE;TRUE;TRUE;TRUE;TRUE}, {2;4;4;2;4;2; 3;4;2;3;1;3}, "")
and returns
{2;4;4;2;4;2;3;4;2;3;1;3}
Checks if a logical expression is met. Returns a specific value if TRUE and another specific value if FALSE.

Step 2 - Find maximum value
=INDEX(List, MATCH(LARGE(IF(COUNTIF($D$2:D2, List)=0, COUNTIF(List, List), ""), 1), COUNTIF(List, List)*(COUNTIF($D$2:D2, List)=0), 0))
LARGE(IF(COUNTIF($D$2:D2, List)=0, COUNTIF(List, List), ""), 1)
becomes
LARGE({2;4;4;2;4;2;3;4;2;3;1;3}, 1)
and returns 4.
The SMALL function lets you extract a number in a cell range based on how small it is compared to the other numbers in the group.
Step 3 - Return the relative position of an item in an array that matches a specified value
=INDEX(List, MATCH(LARGE(IF(COUNTIF($D$2:D2, List)=0, COUNTIF(List, List), ""), 1), COUNTIF(List, List)*(COUNTIF($D$2:D2, List)=0), 0))
MATCH(LARGE(IF(COUNTIF($D$2:D2, List)=0, COUNTIF(List, List), ""), 1), COUNTIF(List, List)*(COUNTIF($D$2:D2, List)=0), 0)
becomes
MATCH(4, COUNTIF(List, List)*(COUNTIF($D$2:D2, List)=0), 0)
becomes
MATCH(4, {2;4;4;2;4;2;3;4;2;3;1;3}), 0)
and returns 2.
Identify the position of a value in an array.
Step 4 - Return a value in a specific position in a given range
=INDEX(List, MATCH(LARGE(IF(COUNTIF($D$2:D2, List)=0, COUNTIF(List, List), ""), 1), COUNTIF(List, List)*(COUNTIF($D$2:D2, List)=0), 0))
becomes
=INDEX(List, 2)
becomes
=INDEX({"DD";"AA";"AA";"BB";"AA";"DD"; "EE";"VV";"BB";"EE";"VV";"EE"}, 2)
and returns "AA".
Gets a value in a specific cell range based on a row and column number.

Narend,
find missing numbers range 1-49 from each row or the whole range?

Hello,
I just stumbled over this website and it's fascinating.
Still I hope you can help me with the topic above since I get a #NUM error when using the formula. I want to extrac an unique list of data sorted by their occurance. For me it seems it works only partially.
Hope you can help. Thanks
Irina,
I have pretty much changed everyting in this post. I hope it works now.
Thanks for your comment!
How can you use large with multiple criteria?? Example looking for top 5 of a list based on name, state and city..
Sara,
See this post: https://www.get-digital-help.com/2012/04/23/unique-distinct-records-sorted-by-frequency/
Hi Oscar, how do you exclude blanks from this? The formula to create the unique distinct list, sorted by occurrences from large to small is almost exactly what I'm looking for...I just can't seem to figure out where to wrap the IF(ISBLANK() to get this thing to exclude blanks.
Joe,

Hi Oscar,
brilliant formulas here. Helped me out a lot.
Is it actually possible to sort list elements with an equal number of occurrence in alphabetical order?
Thanks in advance,
Gerald.
Gerald,
Great question!

Fantastic! Thanks a lot Oscar.

Hi,
How do I create a new unique distinct list from their income?
Client A -$5
Client A -$5
Client B - $1
Client C - $2
Client A - $2
Results will be:
Client A $12
Client C $2
Client B $1
This is a very good formula. At first, it was hard to understand.
With the help of debugger key F9, I was able to analyze it to gain
a better understanding.
Here is my notes using cell D5 as an example.
In cell D5, we have:
=INDEX(List, MATCH(LARGE(IF(COUNTIF($D$2:$D4, List)=0, COUNTIF(List, List),
""), 1), COUNTIF(List, List)*(COUNTIF($D$2:$D4, List)=0), 0))
To make it more readable, we substitute them with array formula:
=INDEX(List,MATCH(LARGE(occurArrayExLargerB,1),occurArrayExLarger0,0))
where
occurArray = COUNTIF(List,List)
occurArrayExLarger0 = (COUNTIF($D$2:$D4,List)=0)*occurArray
occurArrayExLargerB =IF(COUNTIF($D$2:$D4,List)=0, occurArray,"")
To debug, we highlight the individual array formula and press F9 to get their intermediate values:
COUNTIF($D$2:$D4,List) = {0;1;1;0;1;0;1;1;0;1;0;1}
COUNTIF($D$2:$D4,List)=0 (exclusion logic)
{TRUE;FALSE;FALSE;TRUE;FALSE;TRUE;FALSE;FALSE;TRUE;FALSE;TRUE;FALSE}
occurArray = {2;4;4;2;4;2;3;4;2;3;1;3}
occurArrayExLarger0 = {2;0;0;2;0;2;0;0;2;0;1;0}
which means to Exclude Larger occurrences (3 and 4) with 0
occurArrayExLargerB = {2;"";"";2;"";2;"";"";2;"";1;""}
which means to Exclude Larger occurrences (3 and 4) with Blank ""
=INDEX(List, MATCH(2,occurArrayExLarger0,0)))
=INDEX(List, 1) = "DD"
This will result in #NUM! for cell beyond D7 because there are only
5 unique cells. To expand dynamically, we wrap it around with ISERROR:
=IF(ISERROR(
INDEX(List,MATCH(LARGE(occurArrayExLargerB,1),occurArrayExLarger0,0))),"",
INDEX(List,MATCH(LARGE(occurArrayExLargerB,1),occurArrayExLarger0,0)))
Now we can copy and paste it to any cell in column D.
This is the reason we need to define occurArrayExLargerB in addition to
occurArrayExLarger0 because function LARGE(all"",1) will result in #NUM!.
If it wasn't for #NUM! showing in cells beyond D7, we could simplify it to:
=INDEX(List,MATCH(LARGE(occurArrayExLarger0,1),occurArrayExLarger0,0))
without defining a new array formula occurArrayExLargerB.
