Imagine you are the head of training department at ACME Inc. You arrange training programs round the year to empower your team. It is hard work, coordinating between employees, trainers, department heads, venues and coffee machines. What if there is something to help you keep track of all this? I am not talking about getting you a shiny new iPad, you silly. I am talking about a tracker & calendar built in Excel that ties everything together (well, almost everything, you still have to fill the coffee machine.)
This is what we are going to build:

Please watch this 8 minute video before moving on. It explains how the workbook is setup and what it does.

Employee training tracker & calendar – how is it made?
Step 1: Get the data
The first step is to figure out what types of data we need. At the very least, we need 3 sets of data:
- A list of people
- A list of training courses
Let’s assume our data looks like this:
![]()
![]()
All of this data is maintained in Excel tables (named people and courses)
Step 2: Set up a tracker to assign people to training programs
Once we have all the data, we can create a tracker (another Excel table). This allows us to map people to various courses.
Error checking at tracker level:
When you map people to training courses, there are 3 possibilities:
- The mapping could be duplicate
- The course is over capacity
- The mapping is OK
We can use conditional formatting to show these errorsin the tracker so that users will know if everything is ok or not.
We end up with something like this:
![]()
Step 3: Design calendar view on paper
We need to define goals for calendar view. Let’s say the calendar view should answer these questions:
- What courses are happening right now (3 month window)
- How many people have attended the courses?
- What is the total cost
- What is the feedback rating of the courses?
- Show summaries for individual departments or all
Next step is to sketch the calendar view. Here is what I came up with.
![]()
Step 4: Set up slicer & scroll bar form control
Using the instructions in introduction to slicers and introduction to form controls, we set up a slicer on department and a scroll bar to select month.
Step 5: Calculate all the necessary values for calendar view
This is the engine of our calendar view. There are a lot of calculations that go in to showing various summaries and monthly values. Explaining all of them will take forever. Instead, let me summarize the key techniques.
- SMALL formula to fetch the courses scheduled in a particular month
- INDEX formula to fetch various values from people, courses & tracker table.
- SUMIFS (and COUNTIFS) formula to sum & count various things that meet conditions.
- SUMPRODUCT formula when sumifs won’t just get what we want.
- Calculating average rating by selected department employees for a particular course
- TEXT formula to display currency values in the calendar view.
- REPT formula along with star symbols to show rating.
- IFERROR, because #DIV/0! is not the prettiest value on your output worksheet.
Once the calculations are ready, we move to next step.
Step 6: Plug the values in to Calendar view and format
One all the values are loaded to calendar view (thru linked cells, of course), we need to format.
- Use conditional formatting to show borders, fill colors only if a cell has value
- Use conditional formatting to change the color of star rating depending on the slicer selection.
- Set header portion apart with colors and spacer rows.
- Clean up and hide un-necessary stuff.
And the calendar view is ready.

Of course, it’s not that simple.
I have summarized only the key steps. The actual process of making this calendar is a bit more lengthy and time consuming.

I've just taught yesterday to a colleague of mine how to convert amounts in local currency into another by pasting special the ROE.
great thing to know !!!
Chandoo - this is such a great trick and helps save time. If you don't use this shortcut, you have to take can create a formula where =(ref cell /100), copy that all the way down, covert it to a percentage and then copy/paste values to the original column. This does it all much faster. Nice job!
I was just asking peers yesterday if anyone know if an easy way to do this, I've been editing each cell and adding a % manually vs setting the cell to Percentage for months and just finally reached my wits end. What perfect timing! Thanks, great tip!
If it's just appearance you care about, another alternative is to use this custom number format:
0"%"
By adding the percent sign in quotes, it gets treated as text and won't do what you warned about here: "You can not just format the cells to % format either, excel shows 23 as 2300% then."
Dear Jon S. You are the reason I love the internet. 3 year old comments making my life easier.
Thank you.
Here is a quicker protocol.
Enter 10000% into the extra cell, copy this cell, select the range you need to convert to percentages, and use paste special > divide. Since the Paste > All option is selected, it not only divides by 10000% (i.e. 100), it also applies the % format to the cells being pasted on.
@Martin: That is another very good use of Divide / Multiply operations.
@Tony, @Jody: Thank you 🙂
@Jon S: Good one...
@Jon... now why didnt I think of that.. Excellent
Thank You so much. it is really helped me.
Big help...Thanks
Thanks. That really saved me a lot of time!
Is Show Formulas is turned on in the Formula Ribbon, it will stay in decimal form until that is turned off. Drove me batty for an hour until I just figured it out.
