Gantt charts are useful for visualizing a project’s timeline and activity flow. In this article, learn how to create an interactive project gantt chart with drill-down capability using Excel. Here is a demo of the gantt chart we will be creating.

Step by Step Tutorial - Gantt Chart with Drill-down
Please watch below short tutorial to learn how to create an interactive multi-level project gantt chart in Excel. Alternatively, just read on to get the instructions.
If you want to create a similar gantt chart from your data, Please follow below steps.
Step 1: Get your data
You need at least these four columns of data.
Step 2: Make a pivot table from the data
Insert a pivot table from this data. Set it up as shown below. You need,
- Slicer on “module”
- Activity on row labels
- Start date min on values
- End date max on values
Step 3: Create a gantt chart empty outline
In a new worksheet, set up gantt chart outline like below.
You need,
- 4 columns to display activity, start date, end date and duration
- another 90 narrow columns to show the project plan. Feel free to adjust the number of columns based on your needs.
Step 4: Making the left side of gantt chart
The left side portion of our project plan is rather simple to make. We just need to refer to Pivot Table values to get first three columns (Activity, Start and Finish).
We can then calculate the duration using =NETWORKDAYS(start, finish)
After the duration is calculated, add conditional formatting > data bars to it, so that we can easily spot activities that take too long to complete.
Step 5: Gantt chart grid (right side portion)
Now that our gantt chart is ready on the left, let’s complete the grid.
Start by calculating the earliest project start date using min formula =MIN(plan[Start date])
Place this formula in the grid top left cell, as shown below.
Calculate remaining 89 dates by adding +1 working day. Use =WORKDAY(previous date, 1) formula for this.
This will give us a bunch of dates.
Use the next two rows to show month & day portion of this date by referring to the date calculation row. As the cells are too small, merge 2 or 3 of them and show the values.
Now that all the dates are ready, let’s figure out the logic for making gantt chart view.
As shown above, we need a rule to highlight any cell if the date in top row falls between start and finish dates for the corresponding project activity.
To do this, select the entire grid of 100 rows x 90 columns and apply a new conditional formatting rule.
Use “formula” type rule and apply this formula.
=MEDIAN($C6, $D6, M$3) = M$3
Adjust cell references based on your gantt chart setup.

Apply necessary formatting and your gantt chart will be ready.
Step 6: Move the slicer to the gantt chart worksheet
This is the last and easiest step.
Just cut and paste the slicer near the gantt chart. Your interactive chart is ready.
Bells & whistles:
- You can add a conditional formatting rule to highlight current date
- Another rule to highlight alternative rows (zebra-shading)
- Adjust the conditional formatting rule to show completed activities in a different color.
How to update the Gantt Chart?
When ever you have new data, simply update the input data worksheet. Then refresh pivot tables (shortcut: Alt+Ctrl+F5). Your Gantt chart will be updated too.

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.

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.
