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.

  1. Hui... says:

    The best improvement by far is the Collapse Ribbon ^ button !

  2. Alex Kerin says:

    Kind of a shame that some of the best improvements are actually returns to old functionality. One thing I don't like is that to get to recent files I need to do an extra click after File - apart from Save As, that's why I'm usually in the File menu. I like the sparkline options, though they are still as not fully featured as some of the free and pay options out there.

  3. Arti says:

    The collapse button for the ribbon menu is good news. Can you make the ribbon menus stick too?

  4. Jon Peltier says:

    Nine improvements, not ten. You can also select multiple objects in 2007. Click on the Find & Select item at the far right of the Home tab, and the dropdown looks remarkably like your 2010 screenshot.

  5. Chandoo says:

    @Jon.. Thank you. Dumb me, I somehow thought we couldnt select objects in Excel 2007. Just saw the "select menu" and it is there. I have corrected the post and removed the point. I have added the "you can make your own ribbons" instead. Thanks once again.

    @Arti: what do you mean by make ribbons stick?

    @Alex: May be it is my installation, but when I go to "File menu" I see "recent files" by default.

  6. Arti says:

    For example, if I am working with one of the contextual ribbon menus (Pivot tables, Drawing/Chart etc), as soon as I click away from the selected object, the menu tabs vanish. If I click on the object again immediately, then Excel will remember what I was looking at, but if I wander away and click on a Pivot, then back again on the Chart, the menus will 'appear' but not get activated, thereby causing much annoyance and additional clicking.

    I want to "pin" the whole menu (not invididual commands) somehow, so that I can have the menu there for the length of the time I am working with graphics. Excel 2003 used to have the Drawing toolbar you could detach and hover while you were working, but this functionality disappeared in Excel 2007.

    My thought was Excel should just allow a 'pin', similar to the Recently Opened files menu, for the Ribbon Menus as well. If I have not selected any Drawing object, the commands can be greyed out, but I want the menu as a whole to 'stick'.

  7. Chandoo says:

    @Arti... I think MS solved this problem differently. When I select a pivot and go to "design" tab Excel 2010 remembers this and automatically takes me to "design" tab when I reselect the pivot.

    Apart from this you can also define your own ribbon with all the things you normally do. See the above article (I have added this after Jon's comments)

  8. Stephen says:

    Nice feature. About time for a upgrade for MS Office

  9. Arti says:

    Oh... okay. That might be a start. I'd probably just copy-paste the Drawing tab haha. Thanks. I'll definitely give Excel 2010 a try.

    Btw - have you considered getting into / gotten into the world of Excel as it meets SharePoint?

  10. Jon Peltier says:

    Actually, the replacement new thing is probably better than all the rest. One thing that the designers of the Office 2007 ignored was allowing regular users to customize their own interface. Office 2010's interface was expanded in this way to address the huge uproar.

  11. jeff weir says:

    Is there still a limit on how many things you can add to the QAT bar? (I'm too lazy to look myself.)

  12. Chandoo says:

    @Jeff.. it seems to take quite a few, but only shows one line and gives a little arrow button at the end. (summary: shucks!)

  13. Squiggler says:

    The best thing is you can edit the ribbon directly from excel, so now i can create my own bar with just the things I use regularly!

  14. John says:

    One of the annoying things in 07 for me is the Add-Ins menu bar - in 03 I could keystroke directly to menu add ins.. In 07 I needed an extra keystroke just to activate the add-in menu, then the keystrokes as normal.. Hope this marek sense..

  15. Jon Peltier says:

    John -
     
    If you remember the old Excel 2003 Alt-key shortcuts, you can still use them in 2007. To get to the Add-In dialog:
     
    Alt-T-I

  16. Gagan says:

    Dear Arti & Chandoo

    Seen your comments over some issues. Hope you are form India, gone through your comment expecting a pin to command it as a whole, great, hope if someone out of MS have read it, it may be kept in mind while the next R & D of Office Ver. 16

  17. Loranga says:

    Just incase someone forgot CTRL+F1 will collapse the ribbon.

  18. [...] was pleasantly surprised when I ran Microsoft Excel 2010 for first time. It felt smooth, fast, responsive and looked great on my [...]

  19. DK Samuel says:

    I like the sparklines, and the ability to modify the charts

  20. CHRIS LUNA says:

    How do you get rid of the advertisment on the right hand side? If you upgrade then will it take off the ads?

  21. Derek says:

    Once again Microsoft has re-decorated the Office and we are NOT pleased!

    The graphics object selector can be found in the Home ribbon under Find & Select, Select Objects near the bottom of the drop down. You can make it part of the Quick Access toolbar by right click over it and selecting Add to Quick Access toolbar.

    The graphics "cursor" will now appear on the mini-toolbar at the top left of the window.

  22. Vladimir says:

    How to get rid of "Add-Ins" button in Backstage (File)" menu by means of XML code, i.e. to hide, to delete or to disable this button?

    This button is usually situated in the Backstage menu between "Help" and "Options" buttons.

    • Pete Kies says:

      Vladimir, did you ever get an answer to your question?

      I am tying to customize the ribbon UI for a file using XML, and this is precisely the piece I can't figure out. I can hide other tabs, remove items from QAT and backstage - all except the options that are showing up under add-ins in backstage. If there is an XML syntax for referencing this thing and making it invisible, I cannot find it.
