How to Filter Odd or Even Rows only? [Quick Tips]

Ashish sends out this SOS thru email,

I need your help in putting filters . Can we filter the cells on the basis of their even or odd character.

i.e in the table of 1-1000, i wish to filter, 1,3,5,7,…

An odd request, I must say.

But nevertheless, possible in Excel.

If you want to filter odd or even rows only in a list of values,

Assuming your data looks like this:

  1. Just a heads up, you do need to have the Analysis ToolPak add-in activated to use the ISEVEN / ISODD functions. An alternative to ISEVEN would be:
    =MOD(ROW(),2)=0

  2. rather than use a formula, couldn’t you enter “true” in first cell and “false” in the second and drag it down and than filter on true or false.

  3. Nice support by chandoo and team as a helpdesk. Give us more to learn and make us awesome. Always be helpful…….

  4. In case you want to delete instead of filter,

    IF your data is in Sheet1 column A
    Put this in Sheet2 column A and drag down
    =OFFSET(Sheet1!A$1,(ROWS($1:1)-1)*2,,)
    (This is to delete even rows)

    To delete odd rows :
    =OFFSET(Sheet1!A$2,(ROWS($1:1)-1)*2,,)

  5. If your numbered cells did not correspond to rows, the answer would be even simpler:
    =MOD([cell address],2), then filter by 0 to see evens or 1 to see odds.

  6. I sometimes do this using an even simpler method. I add a new column called “Sign” and put the value of 1 in the first row, say cell C2 if C1 contains the header. Then in C3 I put the formula =-1 * C2, which I copy and paste into the rest of the rows (so C4 has =-1 * C3 and so forth). Now I can just apply a filter and pick either +1 or -1 to see half the rows.

    Another way, which works if I want three possibilities: in C2 I put the value 1, in C3 I put the value 2, in C4 I put the value 3, then in C5 I put the formula =C2 then I copy C5 and paste into all the remaining rows (so C6 gets =C3, C7 gets =C4, etc.). Now I can apply a filter and pick the value 1, 2, or 3 to see a third of the rows.

    Extending this approach to more than 3 cases is left as an exercise for the reader.

  7. Hi Chandoo- First of all thanks for the trick. It helped me a lot. Here I have one more challenge. Having filtered the data based on odd. I want to paste data in another sheet adjacent to it. How can I do that?
    For Example-
    A 1 odd
    B 3 odd
    C 4 even
    D 6 even
    I have fileted the above data for odd and want to copy the “This is odd number” text in adjacent/next sheet here. How can I do that. After doing this my data should look like this
    A 1 odd This is odd number
    B 3 odd This is odd number
    C 4 even
    D 6 even

  8. Chandoo SIR,

    I HAVE A DATA IN EXCEL ROWS LIKE BELOW IS THERE ANY FORMULA OR A WAY WHERE I CAN INSTRUCT I CAN MAKE CHANGES , MEANS I WANT TO WRITE ONLY , THE FIG IS FRESH, BUT IN BELOW ROW IT WILL AUTOMATICALLY TAKE THE SOME WORDS FROM FIGS AND MAKE IN PLURAL FORM , WHILE USING ” ARE” LIKE BELOW

    The fig is fresh – row 1
    Figs are fresh – row 2
    The Pomegranate is red – row 3
    Pomegranates are red – row 4

  9. =IF(EVEN(A1)=A1,”EVEN – do something”,”ODD – do something else”) with iferron (for blank Cell)
