Remember Excel School? It was all I talked about between Jan last week and middle of Feb. Then as if someone has pressed mute button, there was not even a single mention about the school. So I thought, why not give you all an update on Excel School and tell you how the classes are going.
Some stats about the program:
- A total of 147 students signed up for the program.
- 3 Students dropped out for various reasons.
- Out of total 12 weeks, we have finished 8 weeks of lessons now.
- We have covered extensively on topics like excel formulas, charting, conditional formatting, formatting, tables and pivot tables until now. We also did a class project.
- In the next 4 weeks we will be talking about data validation, filters, importing data, advanced formulas, macros and do another class project.
- There were a total of 25 lessons, with roughly 800 minutes of video lessons and several downloadable excel workbooks.
- A total of 219 comments were posted by students discussing lesson topics, asking questions and doubts.
What is the student feedback?
While it is a little early, I am very happy to tell you that students are really enjoying Excel School and have been liking what is shared so far. Some encouraging comments I have received are,
I just wanted to give you some feedback on our lessons so far. While I wouldn’t consider Excel school to be a beginner’s 101 course, I wish I had found something with this level of instruction years ago.
I’m having a blast looking at things that I thought I understood well. You have given some new insight into several things that I’ve been able to apply to some workbooks at my job. Just with one powerful little formula tweaks I figured you saved me and a colleague 475 minutes per month on a monthly report that we have to prepare. Over a years time that equates to over $3500. That’s only one instance.
This is the best instruction that I’ve ever come across. You make Excel fun! THANK YOU! Thank you for being so generous with all of the great information that you share. You truly are awesome!
I am a member of your Excel School and continuously watching your postings. I just want to thank you personally for providing me such a good excel tutorials.
I really am learning a lot…I am stubborn and will keep trying till I get the ideas. And you have so many wonderful tricks I never knew about. I got started with you in charting and I have learned so much and done some nifty charts. I am looking forward to learning a lot more from you in the future. I am amazed how much you know and how well you are able to explain things. I thought I was pretty proficient in formatting till I watched week 2 and I have discovered that there is much more I do not know than I do. Can’t wait for the rest of the classes.
I just wanted to tell you that so far in the Excel School, I am blown away with the quality and amount of information I’m getting out of the course. I have always been the excel expert where ever I work, and it’s inspiring to see what you’ve been able to do with it. I didn’t realize there was so much more to learn.
Been taking an online class in Excel. About 6 weeks into it and wow, I have learned a lot. And I am the best Excel user in my department at work. Class is hosted by Chandoo and he is good, really good. Runs a great blog called Pointy Haired Dilbert. A lot of value in this thing: class was approximately $100 for 15 weeks of awesome-ness. … I am loving it. … The surprising thing I have learned is how to better present information for others. I have always taken pride in making good spreadsheets instinctively, but this has made me much better.
My thoughts on the program so far,
To be frank I was *very* nervous when I closed the signups for the excel school. Having 147 students in the class, each with different and probably very high expectations psyched me a bit. To top it, after running barely one week of the program, I had to move from Denmark to India and that posed different challenges (mainly on bandwidth, internet connectivity, free time fronts). Having 2 small babies at home didn’t help either.
But, the students are generous, eager and fun. They lapped up the lessons with enthusiasm and discussed topics with a sense of humor. They supported me when I told them I had to lie low on comment replies during my transit from DK to IN. They didnt mind when a video link was broken or download went 404. They just gave me time to correct it. Few enthusiastic fellas even emailed me and told how *awesome* the classes are and helped me gain confidence. Thank you.
The promised goodies…
I am hoping to start the next batch of Excel School at End of May 2010. I am actively looking for students now…

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.
