I didn’t receive any sample formulas from Friday’s post that included a Friday Challenge, so maybe I stumped everyone when asking you to create an AverageIF Formula Excluding Zeros Across Worksheet Tabs.

Here is the post so that you can learn more about the multi-worksheet tab range reference that was demonstrated.

The Question

In that post I asked if you could create a formula that would calculate the Average excluding zeros (0) across several Excel worksheet tabs using the simple range reference shown in that posting and video.

Maybe everyone thought that AverageIF would work and why bother finding a formula that will work.  However… using the simple multi-sheet / multi-tab reference doesn’t work with AverageIF.

The Solution

We need to go back tot he basics like you may have had to use in Excel 2003, before there was an AverageIF statement.





One such solution is to Sum all values across all sheets and divide it by the count of non zero or non-blank values.

We will use a simple sum function for the numerator.

Then we will use a combination of Index and Frequency to count the number of non-blank and non-zero values across all sheets.

The AverageIF Formula Excluding Zeros Across Worksheet Tabs

Assuming your data is in Cell A2 across sheets grouped between “Dec” and “Jan” as you see here:

Multiple Excel Tabs December to January

Here is the entire formula:

=Sum(Dec:Jan!A2)/INDEX(FREQUENCY(Dec:Jan!A2,0),2)

You can use the Formulas>Evaluate Formula action to check out the results step by step:

The numerator of the formula would as follows:

=Sum(Dec:Jan!A2)/

The denominator of he formula would be as follows:





INDEX(FREQUENCY(Dec:Jan!A2,0),2)

  • Let’s break this formula down.  Try and start from the inner most parts and move out when evaluating formulas:
    • Frequency, this part of the formula will group all the values in cell A2 across the worksheets into those that have a value of zero and those that don’t.

  1. Right out of the box: Please speak in English and leave out the jargon. What is an averageIF and why should I be interested. One look at your first page and you lose me. I have used excel for 25+ years and am still a klutz with it. What I have become proficient with has not been from the books. Hands on trying has been the only way forward. With no example that applies to my line of work and that’s the end. I am a scientist who deals with large spreadsheets with a great deal of inter-cell functions.

    Being a teacher requires you think like your students. You have got to understand that! Anything new has to be presented in the light of relevance, not as if you expect us to already know all about your topic.
