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.

    Its possible to display up to 4 text values.

    Have a look at the screen shot of an example that I had posted way back at the EHA and figure out how its done !

  2. ruve1k says:

    With Excel 2010 you can use Conditional Formatting to apply custom number formats which can display text. (In older versions you can only modify text color and cell background color, but not number formats.) Using CF allows for an even larger number of different display values.

    Hey,
    Thanks, this helps. But how do you do it for multiple values where there is a huge amount of non repeating  text? 

  4. [...] Pivot Tables take tables of data and allow the user to summarise and consolidate the data at the same time. This is a great and very fast method of analysis but is restricted to handling mathematical functions on the value field resulting in numerical summaries. – read more [...]

  6. Jon Gali says:

    There is a very good way actually for handling text inside values area.
    First you create a special column on the very left side and call it ID, and put unique ID (numbers only), and then create a pivot table with:

    Row Labels and Column labels as you like, and in the Values labels use the unique ID number.

    Move the unique ID number (copy paste) somewhere to the right and use vlookup to load the data you need using the ID as reference.

    It is a bit longer way but for me it works perfectly to combine values as you like in any moment.

    hope helps.

    Regards,

    Jon

    Good Day. This is exactly what i have been looking for. However when i try it on my pivot table or even when i try to recreate this exercise using the sample worksheet, i get this error:

    "Microsoft Excel cannot use the number format you typed. Try using one of the built-in number formats."

  11. Letitgo says:

    I found an easy way to get text values in pivot table.

    I create an other worksheet in wich each cell has a formula that copy the pivot table. The trick is that the formula does a lookup for the numbers in the pivot table.

    The formula looks like that:
    =IF(ISNUMBER(table!A1);VLOOKUP(table!A1;Code!$A$1:$B$65;2);IF(ISBLANK(table!A1);" ";table!A1))

    Code is a worksheet where there is a liste of text /numbers correspondance.

    As a bonus The new sheet is easier to format

    Additional trick:
    In my case, i encoded differents codeid with a power(2, codeId-1) so that summing then is equivalent to concatenate them.

    1-A
    2-B
    4-C
    8-D

    yields :

    5 - AC
    14 - BCD

    Hi
    I want to ask if pivot can display dates in pivot field. As in a column i have customers and in row different items i want to know there last purchase date. anyone help in this??

  13. Tushar says:

    Hello Guys, Need your help
    I am doing some analysis of the cycle time of the product i.e how much time a product takes from manufacturing to the central warehouse.
    I have batch numbers for the product and against them i have to pull out the diff. dates
    Like the base date is from where the manufacturing start. So i have the batch number,against it's manuf. date. Now i have to pull out the date when it was quality released.
    I have the quality released data but the data have duplicates, like i will have two dates or may be three for the same batch. So my main objective is to pull out the date which is latest among them.

    BATCH NO. DATE of Mfg. DATE of Quality release
    A1 12/4/2014 (HERE I HAVE TO PULL value)

    Next Sheet
    BATCH NO. DATE of Quality Release
    A1 14/5/2014
    a2 23/5/2016
    A1 12/5/2014
    A1 13/6/2014

    From this sheet i have to pull up the latest date format of date here is dd/mm/yyy

    TIA
