Extracting all rows based on a value of cell without VBA

Question

I\'m really struggling to find an answer to this as online I\'ve really only found VBA solutions to this problem which isn\'t what I wish to learn how to do.

Answer 1

Try this standard formula:

= IFERROR( INDEX( A$2:A$11, AGGREGATE( 15, 6,
ROW($A:$A) / ( $A$2:$A$11 = "O" ), ROWS( $A$2:$A2 ) ) ), "" )

or if you want to limit the size of size of column A

= IFERROR( INDEX( A$2:A$11, AGGREGATE( 15, 6,
ROW($A$1:$A$11) / ( $A$2:$A$11 = "O" ), ROWS( $A$2:$A2 ) ) ), "" )

Enter the formula in G2 then copy it to G2:J10

Answer 2

This does not use array formulas, but does use a helper column. Assuming data in cols A through D, in E2 enter:

=IF(A2="O",1+MAX($E$1:E1),"")

and copy down:

Each of the O rows is marked with a simple sequential value. This makes it easy for the usual MATCH() / INDEX() methods.

Pick some other cell and enter:

=IFERROR(INDEX(A:A,MATCH(ROWS($1:1),$E:$E,0)),"")

and copy this cell both across and down:

Answer 3

The following array formula can be put in row 2 (anywhere from column E onward) and copied across 3 columns and down as far as is necessary:

=IFERROR(INDEX(A:A,SMALL(IF(ISNUMBER(SEARCH("O",$A$2:$A$11)),ROW($A$2:$A$11),""),ROW()-1)),"")

This is entered using Ctrl + Shift + Enter and uses a fixed array (A2:A11). If your array is going to change size, you can make the reference to it dynamic by using INDIRECT and COUNTA so that it always encompasses the used range, like so:

=IFERROR(INDEX(A:A,SMALL(IF(ISNUMBER(SEARCH("O",INDIRECT("$A2:$A"&COUNTA(A:A)))),ROW(INDIRECT("$A2:$A"&COUNTA(A:A))),""),ROW()-1)),"")

What is happening:

The SEARCH function is looking for "O"s, then the IF returns the row number if an "O" was found and nothing if no "O" was found.

The SMALL function is looking for the nth instance of the results returned by the SEARCH function, where n = ROW()-1.

The INDEX function returns the nth value from the array A:A, B:B, etc, where n = the row number returned by the SMALL function.

The IFERROR function is not necessary but it makes for a cleaner dataset, all it does is replace the formulas that didn't return anything useful with a blank instead.

Answer 4

Here is a solution with array formulas. It will calculate extremely slowly, and honestly VBA is a much better solution. You will need to tell excel these are array formulas by hitting "Ctrl + Shift + Enter" after inputting the formulas, this will add the {} around the equation. Finally, drag down the array formulas to see the first "X" results with blood type "O":

First cell formula for "Blood" --> assumes blood is in column A of sheet1 {=IFERROR(INDEX(Sheet1!$A:$D,SMALL(IF(Sheet1!$A:$A="O",ROW(Sheet1!$A:$A)),ROW(1:1)),1,1),"")}

First cell formula for "Name" --> assumes name is in column B of sheet1 {=IFERROR(INDEX(Sheet1!$A:$D,SMALL(IF(Sheet1!$A:$A="O",ROW(Sheet1!$A:$A)),ROW(1:1)),2,1),"")}

First cell formula for "Age" --> assumes age is in column c of sheet1 {=IFERROR(INDEX(Sheet1!$A:$D,SMALL(IF(Sheet1!$A:$A="O",ROW(Sheet1!$A:$A)),ROW(1:1)),3,1),"")}

First cell formula for "Gender" --> assumes gender is in column d of sheet1 {=IFERROR(INDEX(Sheet1!$A:$D,SMALL(IF(Sheet1!$A:$A="O",ROW(Sheet1!$A:$A)),ROW(1:1)),4,1),"")}

Results:

BLOOD   NAME    AGE GENDER
O       Lucy    32  Female
O       John    11  Male
O       Amy     23  Female
O       Linda   11  Female
