This is a guest post by Vijay, our in-house VBA Expert.
Hello Everyone,
This post shows how to make project risk maps using VBA. If you have modern versions of Excel (365, 2019 or 2016 with TEXTJOIN() function), see the Excel Risk Map Template page.
We all have some projects to manage every now and then and there are needs of various trackers that help us in gauging the progress of the same. One of the most important things are heat maps that quickly help us in visually displaying the names of the projects that need special attention and resolve issues that are impacting them.
So go ahead and grab a cup of coffee and read this article that would help you in creating a Risk Heat Map in excel (will use some double shot espresso in the form of VBA code) to help us to the target.
Before we begin – Data for Project Risk Maps
First of all we will understand what we are trying to create here by looking at the image below.
You would have seen a picture like this while managing project risks.
So today we will be learn how to create this in Excel to become more awesome in managing projects.
What is important here is how your data for the projects/entities being tracked laid out. We will use the Excel data tables [structured references] to help us here.
There is a Setup sheet in the excel file where we can add the names of the projects that we will use on the data table, as well as the Probability and Impact have been defined as data tables. This helps us in using their contents as drop down options in the data table.
Adding Named Ranges
We need to use the Name Manager to create named ranges to be able to use the data table columns as drop down items, this is show below.
- 1.Type this in a blank cell and then copy “=tblProject[Project]”.
- 2.Bring up the Name Manager by pressing CTRL + F3, or by going to the Formula’s Tab and clicking on Name Manager.
- 3.Click on New
- 4.Type the name lstProject in the Name box
- 5.Paste “=tblProject[Project]” in the Refers To box and the click on OK.
Repeat this process for “=tblProbability[Probability]” and “tblImpact[Impact]”
Now you can go the actual risk data table and select the Project columns first blank cell and put in Data Validation List here, choose List and put the Source as lstProject. Repeat this for Probability and Impact cells. You will only need to this one time for the first row, new rows when added to the table will automatically contain these settings.
After we have created the above data table, we need to add 3 columns to the right side where we will setup the calculation that will be used to update the risk map.
a) First Column is named as “ProbabilityScore” Since probability has been marked as “A, B, C or D”, we would need to convert this into a number. This is done by using the below formula.
=IFERROR(CHOOSE(MATCH([@Probability],lstProbability,0),4,3,2,1),””)
b) Second Column is named as “SearchString”
=IF([@Status]=”Open”,CONCATENATE(“x”,[@ProbabilityScore]^4+[@Impact]),””)
c) Third column is named as “DisplayName”
=CONCATENATE([@ID],” “,LEFT([@Project],20),IF(LEN([@Project])>20,”…”,””))
Understanding the SearchString Table
When creating the SearchString we are raising the probability score to the power of 4, this is what I have chosen you may select any number that you need. Below is the resulting matrix of numbers that we obtain by doing this.
The last columns in only used for trimming the name of the project to 20 characters of there is a big name, else the actual name of the project is used to display in the Risk Map.
Understanding the Code
So now we are ready to look into the VBA code that helps us in creating the Risk Map.
Public Function showRiskMap(inputRange As Range, searchString As String, dataRange As Range, separator As String)
Dim cntr As Long
Dim tempArray() As Variant
Dim tempDataArray() As Variant
Dim tempString As String
tempArray = inputRange.Value
tempDataArray = dataRange.Value
For cntr = LBound(tempArray) To UBound(tempArray)
If tempArray(cntr, 1) = searchString Then
tempString = tempString & tempDataArray(cntr, 1) & separator
End If
Next
showRiskMap = tempString
End Function
We are sending 4 parameters to this function which are
- inputRange – this is the SearchString columns data
- SearchString – this is a manual enrty such as “x257”
- dataRange – this is the Display Name column from where we will pick the name of the project to display
- separator – this is CHAR(10) which is a line break in case we have multiple projects falling in the same category
We are making use of Array’s here to pass the data from the Table column into the array and then a simple For loop to parse them and show us the results.
I hope you will enjoy this article and this assist in managing your projects in a much efficient way.

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.
