Excel数组公式，仅复制包含字符串的单元格

Question

I would prefer to use an excel array formula (but if it can only be done in VBA, so be it) that copies ALL cells from a column array that contains specific text. The picture below shows what I am after and what I have tried. I'm getting close (thanks to similar, but different questions) but can't quite get to where I want. At the moment, I am getting only the first cell instead of all the cells. In my actual application, I am searching through about 20,000 cells and will have a few hundred search terms. I expect most search terms to give me about 8 - 12 cells with that value.

formula I am using:

=INDEX($A$4:$A$10,MATCH(FALSE,ISERROR(SEARCH($C$1,$A$4:$A$10)),0))

Answer 1

To make this work efficiently, I recommend having a separate cell holding the results count (I used cell C2) which has this formula:

=COUNTIF(A:A,"*"&C1&"*")

Then in cell C4 and copied down use this array formula (The -3 is just because the header row is row 3. If the header row was row 1, it would be -1 ):

=IF(ROW(A1)>$C$2,"",INDEX($A$4:$A$21000,SMALL(IF(ISNUMBER(SEARCH($C$1,$A$4:$A$21000)),ROW($A$4:$A$21000)-3),ROW(C1))))

I tested this with 21000 rows of data in column A with an average of 30 results per search string and the formula is copied down for 60 cells in column C. With that much data, this takes about 1-2 seconds to finish recalculating. Recalculation time can vary widely depending on other factors in your workbook (additional formulas, nested dependencies, use of volatile functions, etc) as well as your hardware.

Alternately, you could just use the built-in Filter functionality, but I hope this helps.

Answer 2

You need to get the ROWS. Put this in C4 and copy down.

=IFERROR(AGGREGATE(15,6, IF(SEARCH($C$1, $A$4:$A$10)>0, ROW($A$4:$A$10)), ROW($C4)-ROW($A$4)+1), "")
