need help to fine-tune a formula that removes blank cells in a column range

[naira]

hi!

I need help in fine tuning a formula that removes blank cells from a column range.

Code: =IF(ROWS(B$2:B2)>COUNTIF($A$2:$A$52,"?*"),"",INDEX($A$2:$A$52,MATCH(1,INDEX(($A$2:$A$52<>"")*ISNA(MATCH($A$2:$A$52,$B$1:$B1,1)),0),0)))

Problem is that each value is appearing uniquely in the result, even though it might be appearing multiple times in the original range. Any suggestions to make the values appear sequentially in the order they appear and multiple times.

Alternately, if someone has a better formula would appreciate if it can be shared.

Following limitations may please be considered:
1. No VBA/ Macros please since they are volatile and tend to disable undo option.
2. No array formulas please (those committed with CTRL+SHIFT+ENTER), since my current solution already uses array formula and that has considerably slowed down calculations. My actual worksheet has about 100,000 cells with the array formula updated on a real time basis.
3. The blank cells will actually not be blank but will be containing a formula and the cells are blank since the result of their calculation is blank.


Regards,

Naira

Sheet1 is assumed to house the relevant data. (Adjust to suit.)

Define Ivec using Formulas | Name Manager as referring to:

=ROW(Sheet1!$A$2:$A$52)-ROW(Sheet1!$A$2)+1

B2, control+shift+enter, not just enter, and copy down:

=IFERROR(INDEX($A$2:$A$52,SMALL(IF($A$2:$A$52="","",Ivec),ROWS($B$2:B2))),"")

Hi Aladin,

Thank you for your prompt reply. Checked your solution and it works perfectly well.
However, in point-2 of my post I had requested that I already have an array solution that is working but it is slowing down my calculations.

Any other solution that avoids arrays and macros?

Check whether the following would be faster with this task...

B1: 0

B2, just enter and copy down:

=IF(A2="","",LOOKUP(9.99999999999999E+307,$B$1:B1)+1)

C1, just enter:

=LOOKUP(9.99999999999999E+307,B:B)

C2, just enter and copy down:

=IF(ROWS($C$2:C2)<=$C$1,LOOKUP(ROWS($C$2:C2),B:B,A:A),"")

Did you try the above set up?
