Yesterday in Formula Forensics 008 we looked at Elkhans MaxIf problem.
However the solution/formula as presented is the final solution to his problem.
Elkhans original worksheet contained other problems and today we will look at this:
I have attached the orginal file as a sample file you can Download Here.
You will see that the MaxIf cell F13 is returning 0, where it should be showing 0.246
Houston, We’ve Had a Problem!
Cell F13 has the same formula we looked at in yesterday’s Formula Forensics: =MAX(IF((Parameter_3=D13)*(Parameter_4=E13),Parameter_5,0))
A quick check of the formula reveals that everything was technically right with the formula, yet the answer is wrong?
To solve this I tried several steps which is the topic of this post:
Examine the logic of the If’s Criteria
The formula =MAX(IF((Parameter_3=D13)*(Parameter_4=E13),Parameter_5,0)) works by calculating the maximum value from the If array.
So step 1 was to look at the logic in the If’s Criteria
That is (Parameter_3=D13)*(Parameter_4=E13)
In cell F15 I entered = (Parameter_3=D13)*(Parameter_4=E13) followed by F9
Excel returns: = {0;0;0;0;0;0;0;0;0;0;0}
This tells me that none of the Cells match the criteria, strange?
Yet manually I can see 4 matching records, below:
Check Cell Length
The next quick step was to look at the length of the text in each cell.
In Column I, I added a =Len(E2) and copied down, there was only 2 characters in each cell, this step eliminated leading or trailing spaces.
Retype the Data
Elkham supplied the source data in an Excel file.
But the Criteria was manually typed by me.
So the next step was to retype some of the original data in Cell E2
Wow an Answer, So obviously there was a difference?
What is Wrong Here?
So obviously there was a difference between the C1 in cell E2 and the C1 in cell E13?
I checked this in 3 ways
1. Type the value “C1” into Cell E2, without the quotes
This returned an answer 0.08 from F2 as it should have.
2. Copy an old “C1” value to E13
This resulted in the correct answer of 0.246 in F13
3. Use a quick Formula
Entering a quick formula
In F17 type =E2=E13
Excel returns False
Showing that the value of cell E2 does not match E13
So what is in E2:E12 ?
As I had typed the values into the Criteria Cells D13:E13, I knew what they were, they were a plain and simple “C1”
So what was in E2:E12 ?
Next step was to look at the Ascii values of the 2 characters in Column E.
In K2: =Code(Left(E2,1))
In L2: =Code(Right(E2,1))
Copy both down to Row 13
Bingo !
The Character C in cell E2 wasn’t the same as the Character C in E13 ?
Yet both cells contained a Calibri Font.
If I now type in a spare cells:
F18 =Char(63), Excel displays a “?”
F19 =Char(67), Excel displays a “C”
Yet Cell E2 is clearly displaying C1 with a First Character Ascii code of 63 which should be a ? mark.
I suspected that it had been copied and pasted from MS Access, So I shot an email back to Elkhan, asking “What the source of the data was?”.
The response came back that “The data had been copied from a Russian (Cyrillic) version of an MS Word File and pasted into an English version of Excel.”
I can’t explain what has happened but somehow the character sets and associated values got scrambled when copied the data from the Russian Word Document into Excel
If you have had experiences like this or can explain what has happened please do so in the comments below:
Solution
The Solution was now easy
Use Search/Replace
Copy the contents of cell E1,
goto Search/Replace or Ctrl H
Find: Paste the contents of Cell E1
Replace with: C1
Conclusions:
- Be careful when receiving data from foreign language files, including word and Excel files
- Check summations based on such data to ensure its integrity
- Be methodical in tracking down problem cells

I’d suggest simply using the subtotal function and filtering the data using the Win/Loss column. You get the same results and the formula is more comprehensible.
@John
That is one option.
There are times however when you want to see the whole data table or a filtered subset and still want to produce summary reports against an unfiltered field.
Is there a particular reason why you are using a comma and the unary (–) operator for the second array in the SUMPRODUCT formula? It seems to work the same if you were to string the arrays together using the asterisk (*). The advantage is that SUMPRODUCT treats the entire string of arrays as a single array.
@Mathew
Your correct, There is no difference.
I thought it may have been easier to explain this method.
Is there a way to do this on a large set of data? As in ~100,000 rows? When I try I get an error because the formula becomes too long. It says the max length of a formula is 8,192 characters. Excel 2010.
How do I incorporate a specific text within a cell for the second array. For instance, – -(C7:C13=”Apple”)
when I chose a specific text the formula does not work.
@RB
I am not sure what is the issue as if I use the sample data in the post the following work fine
Count:
=SUMPRODUCT(SUBTOTAL(3,OFFSET(C7:C13,ROW(C7:C13)-MIN(ROW(C7:C13)),,1)), –(C7:C13=”L”))
Sum:
=SUMPRODUCT(SUBTOTAL(3,OFFSET(C7:C13,ROW(C7:C13)-MIN(ROW(C7:C13)),,1)),(C7:C13=”L”)*(D7:D13))
You may want to check that there are no leading or trailing spaces in your list of Apples
I should have given a better explanation. Heres my situation. I have a column with cells filled with names like Column 1, Column 2, Pier 1, Pier 2, etc. If the cell just contained Pier and searched for that it works. But because it has other characters in the cell its not recognizing the pier. So how can I extract specific characters of a string of text in this formula?
Hopefully this was a better explanation
Hello-
This formula works pretty well for me except that it slow down excel and prevents some of my macros from working. I was wondering if there was a way to program this in VBA so that excel isn’t always trying to recalculate it. I would like to use a push of a button to get it to run then paste in a cell.
Thanks!
I am trying to sum filtered data in a column, but would want to ignore the negative values in the column. How to go about doing this?
@Akshay
Why not just add a filter to that column to only show the values greater than zero?
The negative values are required for reporting purposes, but their effect on the total is distorting the required output. Please advise.
@Akshay
I’d suggest making a post in the Chandoo.org Forums

I have this working for counting and summing, however, I have a list and for the second array, I need a criteria. That is, I’m looking for b13:b200=”01.??.??” or =left((a1,2) or something like that. These types of criteria matches do not appear to work as I get a blank as a result.
Thanks!
@Bob
As your formula b13:b200=”01.??.??” looks like you are trying to check the first day of the month of the range
What about trying Day(B13:B200)=1
Hai Experts,
i understood this formula well and working fine in MS Excel 2013
but when the same am trying to place in google Spreadsheet it shows error as
“SUMPRODUCT has mismatched range sizes. Expected row count: 1. column count: 1. Actual row count: 2014, column count: 1.” and as a result #VALUE! Appears in cell.
Can anyone please help me how would i get it done in Google Spread sheet
or is there any other formula as a substitute for this.
Thank you very much.
thanks for providing this.. but why does excel keeps on prompting Circular referencing in cell D3?
@Vivek
I don’t know
I just downloaded the file and it is working fine and not showing that error
Goto the Formulas, Calculation Options Tab and check that Calculation is set to Automatic
What version of Excel and Windows are you using ?
I know that this forum is for MS Excel, but I am trying to help someone who is working in Google Sheets. The below formula works in Excel but Google Sheets returns:
“SUMPRODUCT has mismatched range sizes. Expected row count: 1. column count: 1. Actual row count: 39000, column count: 1.” and as a result #VALUE! Appears in cell.
This is the same problem asked by Srichirin above. Does anyone know if there is a formula for Google Sheets that will replicate what MS Excel does?
=SUMPRODUCT(SUBTOTAL(3,OFFSET($C$6:$C$39500,ROW($C$6:$C$39500)-MIN(ROW($C$6:$C$39500)),,1)),- -($C$6:$C$39500=H1),($D$6:$D$39500))
Trying to find a SUMPRODUCT formula that counts the word Closed by date for the last 7 days in a filtered list.
=COUNTIF(M:M,”>”&TODAY()-7) works ok for unfiltered count Column M contains Closure dates (blank if open) and Column L is Status Open or Closed

I used this formula and worked like a charm! But, now I’ve been requested to use it but adding not one but two criteria in the same formula. For instance the sum I was doing added negative and positive numbers. I’ve been asked to use the exact same formula but adding that only positive numbers were considered… any idea on how to do this?
How exactly do you do sum filtered cells when two criteria are need not just one?
Thank you so much brother literally I have been struggling since morning to get the sum of the filtered category, however, after reading your blog attentively i got my solution, so thanks a lot once again.
