Today, lets learn how to make a simple timer app using Excel. First some background…,

Rubik's CubeRecently, 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.

Building a simple timer using Excel VBA to track time - demo

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.

  1. You want to start the timer
  2. 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.

    Great stuff! I can understand how to add a slicer to the pivot table, but how do you implement the departmental selector on the 'Filter' formula scheme?

  2. Claus Andersen says:

    Just saw this on your Youtube channel, and it’s areat idea...!

    An easy way to overcome the "ugliness" of pivot tables and get it to look nice (in the format of the Output sheet), would be to simply build a sheet with the nice map at the top, a pivot underneath it and a slicer next to formatted map and then reference each of the 9 cells in the formatted map to the “related” cell in the Pivot.

    Keep up the good work!

    Hi Chandoo,

    This is great! Curious how to make additional columns operate the same as the Department column (ex. have a "manager column") that would allow you to sort a 9 box by manager, area, or team in addition to department?

    Feel free to email me if needed! mfry01@minnetronixmedical.com

    Happy New Year

    • Ed says:

      I am curious about the smae thing. I would like to populate the 9 box with other views as well by adding additional columns. IE., I would like to add location, region, etc. Thank you.

  4. Matt says:

    This is great, thank you!

  5. Al says:

    How can i see the whole data set of all the teams in the output table. Need a formula that will pick up all the employees

  6. Heather says:

    Hello,
    Love the template. Thank you. Question - the drop down to pick a department on the Output tab does not seem to work on the downloadable template. Am I doing something incorrectly?
    Thank you!

    • Chandoo says:

      Hi Heather... Thank you. I am using Excel 365 to make the calculations. If you are using an older version of Excel, then the drop-down filter won't work.

  7. Rose says:

    Hi
    I was able to follow your 9 box grid and modified based my needs. However, you tutorial did not show how to you create the filter for the "Pick a department. Can you kindly share how to create that filter that updated the grid. Thank you.

  8. Rose says:

    I am working on this project but I am struggling with the data validation for the department. I copy the worksheets data entry and output as the managers want to see different tabs for each managers.
    I updated the source reference for each tab but It does not update the grid based on the new source. The list was updated but it does not populate the grid based on the performance and potential listed.
    In addition the hyperlink Update Data and View Talent Map no longer works. Can you please help me.

  9. Emmanuel Jose Vasquez says:

    I keep getting this error message in the pivot table:

    This formula is invalid or incomplete: 'The expression is not valid or appears to be incomplete. Please review and correct the expression.
    The following syntax error occurred during parsing: Invalid token, Line 1, Offset 14, ‘.

  10. Hi, I used your 9-box excel template with excel 365. First off, thank you so very much. It is incredibly helpful!! My only question is that the boxes aren't big enough for all of the employees (specifically the middle which we call 'Core Employee'). Is there a way to make the boxes larger? Even though it is in excel, I am not able to increase row height (like I normally do in a speadsheet). Any ideas? Thanks again, Jody

  11. Prish says:

    Hi Chandoo,

    Thanks for the great content. Re. 9 box grid, pls advise how do I increase the size of the box to accommodate more names?

  12. Nabil says:

    Merci Chandoo pour le modèle proposé,
    j'ai une question et un souhait est il possible de développer davantage ce modèle en insérant la photo de chaque employé.

  13. Leah says:

    Hi Chandoo!

    Great tutorial and tool, thank you! Your tutorial didn't include how to create additional filters on the "Output" tab. Could you please share how you did it?

  14. Geno says:

    Can this be done exactly in google sheets?

  15. Joanne says:

    Hi Chandoo,
    Thanks for the video it was really helpful. Is there any way to multi select the dropdown to display multiple or all departments rather than just one at once?

  16. Dana says:

    Hello Prish

    I have Microsoft 365 and I am struggling to make the boxes larger/unable to increase row height; any idea how you made this work? Specifically in the Output tab where the map is?

    Many thanks

  18. Connie Richards says:

    Is there a way to change the 9 box wording descriptions, i.e. Work Horses, to our own internal langauge?

  19. Zee says:

    Hi Chandoo, this is awesome and has worked perfectly. Due to a big organisation the 9 box grid on the output file is too small. I tried adjusting using the row/width ribbon under the format ribbon however it doesn't seem to work. Is there an easier way to adjust this?

    Thanks!

  20. Huy Nghi?a says:

    When I drag the formula, it doesn't work, and the order I use with the data changes. In the beginning, the order is it is " candidates," " potential," and " performance," but when it goes to another column, it is " Potential," Performance," and "Candidates."Can you help me? Thank you very much, sending love from vietnam

  21. Lucia says:

    Hi- I am working on the 9 grid project and I am trying to expand the box since I have over 100 names on a few of the columns. How do I do that?

  22. Zara says:

    Hi, Thank you this is great stuff and really useful.

    As well as department as demonstrated on your clip, how can I display all candidates on the grid at once?

    Many thanks in advance
