In this article I will show you how to extract the most frequent value (text or number) between two dates in a column.

Array formula in D18:

=INDEX($C$3:$C$12, MATCH(MODE.SNGL(IF(($B$3:$B$12<=$C$16)*($B$3:$B$12>=$C$15), COUNTIF($C$3:$C$12, "<"&$C$3:$C$12), "")), COUNTIF($C$3:$C$12, "<"&$C$3:$C$12),0))

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 D18

Step 1 - Calculate rank order if sorted

The COUNTIF function counts values based on a condition or criteria, the < less than sign makes the COUNTIF calculate a rank number if the list were sorted from A to Z.



COUNTIF({"BB"; "CC"; "AA"; "CC"; "AA"; "EE"; "DD"; "EE"; "BB"; "AA"},"<"&{"BB"; "CC"; "AA"; "CC"; "AA"; "EE"; "DD"; "EE"; "BB"; "AA"})


COUNTIF({"BB"; "CC"; "AA"; "CC"; "AA"; "EE"; "DD"; "EE"; "BB"; "AA"}, {"<BB";"<CC";"<AA";"<CC";"<AA";"<EE";"<DD";"<EE";"<BB";"<AA"})

and returns


Step 2 - Check which values are in range

The IF function returns the rank number number based on a logical expression. It returns boolean value TRUE if the value is in the date range. If boolean value is FALSE the IF function returns "" (nothing).





IF({1;0;0;0;1;1;0;1;0;0}, {3; 5; 0; 5; 0; 8; 7; 8; 3; 0},"")

and returns

{3; ""; ""; ""; 0; 8; ""; 8; ""; ""}.

Step 3 - Calculate the most frequent number

The MODE.SNGL function returns the most frequent number in a cell range or array.



MODE.SNGL({3; ""; ""; ""; 0; 8; ""; 8; ""; ""})

and returns 8.

Step 4 - Find position of most frequent number in array

The MATCH function finds the relative position of a value in an array or cell range.

MATCH(MODE.SNGL(IF(($B$3:$B$12<=$C$16)*($B$3:$B$12>=$C$15), COUNTIF($C$3:$C$12, "<"&$C$3:$C$12), "")), COUNTIF($C$3:$C$12, "<"&$C$3:$C$12),0)


MATCH(8, COUNTIF($C$3:$C$12, "<"&$C$3:$C$12),0)


MATCH(8, {3; 5; 0; 5; 0; 8; 7; 8; 3; 0},0)

and returns 6.

Step 5 - Return value

The INDEX function returns a value based on row number (and column number if needed)

INDEX($C$3:$C$12, MATCH(MODE.SNGL(IF(($B$3:$B$12<=$C$16)*($B$3:$B$12>=$C$15), COUNTIF($C$3:$C$12, "<"&$C$3:$C$12), "")), COUNTIF($C$3:$C$12, "<"&$C$3:$C$12),0))


INDEX($C$3:$C$12, 6)

and returns "EE" in cell D18.
