Today, lets learn how to make a simple timer app using Excel. First some background…,
Recently, I learned how to solve Rubik’s cube from my nephew. As a budding cuber, I wanted to track my progress. Initially I used the stopwatch in my iPhone. But it wont let me track previous times. So I thought, “Well, I can use Excel for this”.
So I made a small timer app using Excel. Its quite minimalistic. It has a single button. I press it and it tracks the start time (date & time stamp). If I press the button again, it records the duration.
This way, I can see my progress over next few weeks and may be plot the trend.
Demo of the Excel VBA timer
Here is a short demo. This is what we will be building.
Tutorial to make a timer in Excel
To make a timer app in Excel, first we need to understand the logic for this. If VBA apps can be defined on a scale of 1 to 10 (1 being easiest to develop and 10 being most complex), our timer app can be classified as 1.5. It is really simple. But nevertheless, it is a good idea to list down various ingredients and basic logic to follow.
So we need,
- A table to store the time stamps & durations
- A button (simple text box will do) to start & stop the timer
Set up the timer worksheet
In a blank worksheet, make space for a 2 column table. Type Time stamp & Duration as column headings and make a table from these (CTRL+T to insert the table)
Note: For the macro to work, you do not need a table. Any 2 column range will do. A table makes our timer app look sexy.
Also, insert a rounded rectangle and format it to look like a button (from Format Ribbon > Shape Styles, select something slick and pretty)
In a blank cell, type the word “Start”. Name this cell as timer.button.label
Now, click on the rounded rectangle button, go to formula bar and type =timer.button.label
💡 Tip: Yes, you can assign names or cell references to shapes. This way, whatever text is in the cell will be shown inside the shape.
Other names to make:
Although we can write VBA code without creating these names, our code will be readable with these names. So here we go:
- Select the header “Timestamp” of the table and name it as time.stamp.start
- Name the table as Durations from Table Design ribbon
- In a blank cell, write the formula =COUNTA(Durations[Timestamp])
- This counts how many timestamps are already inserted.
- Now name this cell as count.of.timestamps
We are done. Lets roll in to VBA.
Writing the VBA code for timer
Open VBE (Visual Basic Editor) and insert a new module in your timer workbook. There write this code.
Sub startStopTimer()
If Range("timer.button.label") = "Start" Then
Range("time.stamp.start").Offset(Range("count.of.timestamps") + 1).Value = Now
Range("timer.button.label") = "Stop"
Else
Range("time.stamp.start").Offset(Range("count.of.timestamps"), 1).Value = Now - Range("time.stamp.start").Offset(Range("count.of.timestamps"))
Range("timer.button.label") = "Start"
End If
End Sub
Assign this macro to the timer button
Right click on timer button and choose “Assign macro”. Select the startStopTimer sub from the list and click ok.
Now go ahead and test it. Assuming you have used same names as per this post, your timer should work.
How this macro works?
When you click on the timer button, you want one of the 2 things to happen.
- You want to start the timer
- You want to stop the timer
What you want to do can be checked with this logical check.
Range("timer.button.label") = "Start"
If this is true, then you want to start the timer.
Else, you want to stop the timer.
If you want to start the timer
Then, we need to go to the last row of the table + 1 and insert current time (now) in that cell.
This is done by,
Range("time.stamp.start").Offset(Range("count.of.timestamps") + 1).Value = Now
Once we do that, we need to change timer button’s text to “Stop”.
This is done by,
Range("timer.button.label") = "Stop"
If you want to stop the timer
Then, we need to go to the last row’s 2nd column of the table and print the difference between latest time (now) and starting time (last row, first column value)
This is done by,
Range("time.stamp.start").Offset(Range("count.of.timestamps"), 1).Value = Now - Range("time.stamp.start").Offset(Range("count.of.timestamps"))
Once we do that, we need to change the button text to “Start” by using this code:
Range("timer.button.label") = "Start"
That’s all. Our VBA code is rather simple.
One last step, formatting the duration
If you look at the duration, it could read something like 0.0042354. This is because duration is displayed as a fraction of day. So 0.0042354 means the duration is 0.42% of a day.
Now, wouldn’t it be better if we can show this in minutes and seconds?
To do that, select the entire table column of durations, press CTRL+1
Then, set formatting as custom and type code as [mm]:ss
And you are done!

Do you use Excel for tracking time?
I know many companies use Excel based trackers to keep track of employee time. I personally use time tracking features of Excel for needs like this all the time.
What about you? Do you use Excel time functions like NOW, TODAY and VBA to track progress? What techniques you apply? Please share using comments.

the templates are great (I bought the combo).
What I'm missing is a way to have the project gantt chart and reporting with the data per resource, in such a way that I can also show the occupation per resource on an extended gantt chart.
So with hours entered per person per project or sub-activity, to show a gantt chart of how many hours/days a person spent on which project (or plans to spend).

Hi Chandoo,
Funny I have a post on the value of MS project lined up which I will post when the current monster project I'm working on finishes and I get some free time!
I'm not sure this would help with any of the projects I've worked on, closing down a to do list seems like more effort than it's worth, but it might be useful for some things. I guessing it doesn't, but does the time stamp not update when you recalculate the work book?
keep up the good work!
Ross
@Ross.. Thanks for sharing your ideas... I think to do lists are a great way to keep up with project activities and ensure accountability from individual team members, when they are implemented right.
"I guessing it doesn’t, but does the time stamp not update when you recalculate the work book?"
Your guess is right. When you change the calculation mode to "iterative", excel takes care of the nittygritties and retains older values in circular references in formulas.

Chandoo,
I really do not see any befit to this function in Excel unless it was somehow tied into some other chart. That is say a scheduled activities % complete is based on the to-do list.
The only way this chart would be useful is if no one was assigned none dependent task that could be done by anyone. The cases were both of these conditions are true are so few and far between it really makes this chart worthless.
@Brian... Once you have a todo list up and running, it is easy to get metrics out of it. I didnt propose it as it might look a bit too micro-management-ish.
I am able to understand what you meant by "The only way this chart would be useful is if no one was assigned none dependent task that could be done by anyone. The cases were both of these conditions are true are so few and far between it really makes this chart worthless."
Can you explain?
"Chandoo"
What I mean is this. Lets say you have 10 task which are part of one activity/WBS that is in your schedule. One there are very few cases were many people would be assigned to complete this one scheduled activity with no direction being given who should what of the 10 task. It is poor management, and the task 90% of the time would not get done in a timely manner if say 4 people were responsible. Secondly, you are assuming all 10 task are independent of each other. You might need to do task 1 thru 3 before you can do task 4, and to do task 7 you might need to do 4 and 6. Thirdly, the time it would take to compile and then fill out the to-do-list even in limited applications is really not worth it.
I just see almost no applications why a team would need to inform others separate from the schedule that they have completed a task on a to-do list unless anyone of the 4 people could of completed that task.
My point is, there might be a few very limited applications for this type of list but this list would be worthless as a Project Management tool in every other case.
However, change this from a to-do-list to a document change log and it is perfect. Instead of to-do it is the documents name or summary of what changed in the document. The person is who edited the document, and the time stamp is when they checked it in. But I do not know why you would use excel when there is free software you can use commercially that is 10 times better that does document management.
I think using excel to do Project Management over a real Project Management application is a bad idea. Unless you are running a very small, simple project, the time and effort is a lot more to use excel compared to the cost of the Project Management software.
This comes back to my point, I love your site, however, just because you can do something in excel does not mean you should do it. To often the time it takes to use excel is wasted 10 times over from the cost of doing it in an application designed to for the specific application.
@Brian: The todo list mentioned here is meant to keep track of all the tasks for which detailed planning is not necessary but some sort of tracking is needed. These are not be confused with project activities (a la gantt chart).
I like your suggestion about using this as a document tracker. Pretty cool use.
Coming to your point about excel as a real project management tool, well, I have my views, but in a serious project environment, it would surely payoff to have a dedicated project management application.

Chandoo,
Wonder how the timestamp column will maintain its previous data. Both Today() and Now() functions will update as and when the next timestamp happens.

I've combined this with the issue tracker since I like the automatic date stamp, but one thing I'm noticing is that I can't replicate the chart that goes along with the issue tracker because the cells that are referenced have the formula that inserts the time stamp instead of a the actual date value. All the dates of the last 30 days display 0 when they should have a value.
Is there a way around this?
I have edited the chart so that my team members can update the percentage completion of the assigned tasks. When the cell is updated, i would like the time stamp to update. How would I manipulate the formula to update whenever the drop-down list is changed?

Excel is great however sometimes you need to get a better idea of what tasks each person on your team is working on at any given time. We've developed a web app that can do just that! Each person has a list of tasks, listed in the order they have to complete them.
HII,
I want to expand the database through excel where i am working on 11 cities as of now and i want to expand it upto 50 cities and hence forth the data related to it will also expand so i want to make it precise where i can get updates also that this work is required to be done at that particular day or date
Thanks for making all of this information available for free. I am currently using excel to track everything for the first time. I later plan to output our information here with a more visual presentation. Wish me luck!
Can some one point me out to some additional direction on the "Who Finished it?" column? Something more 'basic' for a newbie excel guy? lol I got everything else working on this tutorial but that column. I can't seem to recreate it and I know a lot of it is due to lack of knowledge with VB code. I'd like to recreate this column very much 🙁
Dear Chandoo,
Thanks for the team to do list, kindly let me know how to set the column who " finished it " from another work sheet
Hi Chandoo,
Unable to download it - can you please check the link and confirm.
Great inhisgt! That's the answer we've been looking for.
Hi Team,
I know u all are the best programmers in the world!!! that's I am here to rectify my issues. here is my question please ans me as soon as possible before 8-3-2017 its really urgent.
I have a project named the production tracker.
1) I require the user form which shows the names of the Associates which are linked to the different tracks. when the user is selected the particular track related details and dropdowns should appear.
2) I need to track the associate needs how much of the time to complete the particular task. with start stop and pause and resume timer.
3) It should display the daily count of the production and save the data to the another Excel file.
this production tracker should save all the data no matter how many people logs in into it.
Please help me for this it will be very appreciated.
you can directly email me on my mail ID: tusharkch694@gmail.com
