If this Excel problem is a Bollywood (Indian movie) plot, it would go like this:
Situation: Your boss gave you a worksheet. It has a lot of number chunks. And you need to calculate the sum of each chunk. Quickly!
Twist #1: The villain (your boss, who else) has abducted your spouse. For every extra hour you spend on the problem, your boss will make your spouse go thru one of the boring 97 slide strategy presentations. And his laptop is full of those strategy presentations.
Twist #2: The F1 key on your keyboard is missing.
Twist #3: The coffee machine in your floor is broken again.
Twist #4: And just when you are pressing CTRL+S, the movie steers in to an item song.

Fortunately, no one abducted your spouse. And hopefully the coffee machine is working. But the Excel problem remains unsolved.
Sporadic totals
This problem is based on a call I received last week from one of our readers in UK. He had a worksheet full of numbers with blank rows between every few numbers. And he wants to calculate the totals of individual chunks of numbers quickly. He cannot write one formula and paste it everywhere as the chunks are not uniformly sized. He cannot write individual formulas as the data is very large.
So what to do?
If we are still in a Bollywood film, you can write all the 10,000 formulas and simultaneously sipping screwdrivers & shimmying to a snazzy song with sexy starlets.
Alas, this is not a movie.
But we still manage to look awesome. Thanks to superb sidekicks – Goto Special & Autosum.
Calculating Sporadic Totals in a second
See this short video to understand how to calculate sporadic totals in a few seconds. With the time saved, you could fix yourself a cocktail (or coffee) and hum a beautiful song.
Watch the video on our YouTube Channel or Facebook Page.
Sporadic Totals – Alternative treatment
It is an awesome co-incidence that both MrExcel (Bill Jelen) and Kevin Lehrbass also published videos about this concept around the same time. MrExcel shows how to use VBA to do this, where as Kevin talks about using formulas. Check out both videos too.

Leave the drama to movies, Learn Excel
We all love film drama like blowing up cars, high-speed chases, super-human stunts and spicy songs. But you sure don’t want that in your life. So learn Excel. Save time, use that to enjoy the drama elsewhere.

Infact, instead of using =ISEVEN(B3), how about to use =ISEVEN(ROW())
So it takes away any chance of wrong referencing.
I like Daily Dose of Excel
I like it.
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
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.
Just for clarification, is Ashish looking to filter by even or odd Characters or rows?
so many functions to learn!
Nice support by chandoo and team as a helpdesk. Give us more to learn and make us awesome. Always be helpful.......
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,,)
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.
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.
Another way =MOD(ROW();2). In this case, must to choose betwen 1 and 0.

Thanks for the tip, it worked like magic, saved having to delete row by row in my database.

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
Hi! Could you please help me find a formula to filter by language?
Thank you!
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
=IF(EVEN(A1)=A1,"EVEN - do something","ODD - do something else") with iferron (for blank Cell)
