Automatically insert timestamps in excel sheet using formulas

What is a time stamp?

Often when you use excel to track a particular item (like expenses, exercise schedules, investments) you usually enter the current date (and time). This is nothing but timestamping. Once the item is time stamped, it is much more easier to analyze it.

So how do I generate timestamps in Excel?

We all know about the now() formula in excel and how it tells you the current date and time. The only problem with it is that, when you press F9 or recalculate formulas, the now() will be changed to reflect latest date and time. Thus we cannot use NOW() as a time stamp.

A good alternative (although manual) is to use keyboard shortcuts CTRL + ; or CTRL + : to insert current date and time in the active cell. Since this places the value, we don’t need to worry even if the date or time changes. But the only issue is, every time you need a time stamp you have to press the 2 keys.

A better way to get timestamps in excel is to use a special type of formulas, called as circular formulas.

What the heck is a circular formula?

A circular formula refers to itself (or to another cell which in turn refers to this cell). Confused ? Well, let me give you an example.

=if(A2<1000, A2+1,A2)

Now the above formula is normal, but the moment you write it in the cell A2, you have made it a circular formula. So, each time you run the formula (by pressing F9) the value in A2 will go up by 1, just like an incrementing counter.

But here is a thing you should be aware of: There is a setting called “iterations”, it tells excel how many times it should run a formula before finalizing the result.

This setting wouldn’t make any sense in case of regular formulas. But it is very important for circular formulas. If not for this, excel would go in to an infinite loop and stall.

Now, by default iterations in formula computation is turned off. That means when you write a circular formula or create a circular reference, excel shows you a message warning you and it doesn’t evaluate the formula.To turn the iterative calculation, and thus enable usage of circular formulas, go to menu > tools > options > calculation tab and check the iteration box. In excel 2007, you can go to office button > excel options > formulas > iteration area.

formula-calc-iterations

As you can see the default max. iterations per formula execution is 100, which means, every time you run the circular formula, excel calculates it 100 times before presenting the value. So our formula =if(A2<1000, A2+1,A2) written in cell A2 would go up by 100 every time you run.

Back to Generating Time Stamps

Now that you are knowledgeable about circular formulas, here is how we can refine the “time stamp generation” problem:

if the cell doesn’t already have time stamp, insert current date time using now(), otherwise leave the value as it is

and we will trigger the formula once we make certain changes, for eg. whenever you  enter data, you can tell excel enter timestamps. See this:

timestamps-in-excel-formula

The formula itself is very simple:

=IF(C3<>"",IF(B3="",NOW(),B3),"") in cell B3.

What it does?

It checks cell C3 and whenever it is not empty it runs the circular formula IF(B3="",NOW(),B3) which fetches NOW() value only if the cell B3 doesn’t already have a value, thus serving timestamps.

The above formula works only if you have enabled iterative calculation mode as described above.

    Why didn't you include the mitigation or risk IDs in the chart?

    • Chandoo says:

      You can easily add such detail by modifying the TEXTJOIN function. Another way to use them is to add a slicer to highlight all risks that have a specific mitigation strategy or team member assigned to them. I left out those bits fto keep the article short.

      • Rajesh says:

        I tried adding a slicer filter for the mitigation step but the TEXTJOIN is not affected by it. I added a helper column called "Visible" using the AGGREGATE function but I am unable to think of a method to pass that on to the map.
        Could you please help, Chandoo?

        Thanks

        Hello everyone,

        Another amazing tutorial, great content and tips! My question is about slicers. How do you add slicers to this matrix? I've added 2 columns in my workbook table (Work Stream and Project Name) and I want to be able to filter (slice) the matrix on Project Name, but having some trouble with this. The slicer works fine in the data table, but how do I connect it to the risk matrix, so that only risk titles show up for the selected project?

        Many thanks in advance for your guidance,
        MyvJ

    Hi

    I've tried to get your formula to work, but likelihood / impact 1/1 does not seem to work.

  4. Sally says:

    Hi Chandoo

    Awesome instructions! Thank you so much, this really helped me.

    I was wondering if it would be possible to list the Risk ID number along with the Risk Title with a dash in between, rather than a bullet point? I have had a try at this but I keep getting a #VALUE error. I can see it's wrong but can't figure out what it should be instead. If you have time do you mind letting me know what I'm doing wrong?

    {=" - " & TEXTJOIN(CHAR(10)&" - ",TRUE,
    IF(RiskRegister[Likelihood]=$A17,IF(RiskRegister[Consequence]=F$3,CONCAT(RiskRegister[ID],RiskRegister[Risk Title]),""),""))}

    Thank you!

    Sally

    • Chandoo says:

      Hey Sally, You are welcome.

      I think the CONCAT inside TEXTJOIN is the culprit. Try this and hopefully you should see the ID too.

      {=" - " & TEXTJOIN(CHAR(10)&" - ",TRUE,
      IF(RiskRegister[Likelihood]=$A17,IF(RiskRegister[Consequence]=F$3,RiskRegister[ID]&RiskRegister[Risk Title],""),""))}

      • Sally says:

        Hi Chandoo
        You're a legend! Thank you so much! I had to make a minor tweak but otherwise it worked perfectly. Here is the tweaked version in case it helps anyone else:

        =TEXTJOIN(CHAR(10),TRUE,
        IF(RiskRegister[Likelihood]=$A8,IF(RiskRegister[Consequence]=C$3,RiskRegister[ID]&" - "&RiskRegister[Risk Title],""),""))

        Thank you again!

        • Ruben says:

          Hi, Im not able to change the formula when trying to add risk Id instead of bullet point.

          trying this: ="• "&TEXTJOIN(CHAR(10)&"• ";TRUE;IF(risks[Probability of Occurance *]=$C5;IF(risks[Severity of potential Impact *]=H$8;risks[Risk ID]&". "[Title *];"");""))

          Cant see any solution on this.

          thankful for help

  5. kris says:

    Hi Chandoo,

    This is perfect - One quick question, How can I add a hyperlink to the risks - So that I can click on the particular risk and it takes me to the actual row of that item.

    Many thanks in advance.

  6. SY says:

    HI Chandoo,

    Is there a way to only display filtered item. Once the list gets big, it's hard to see all risk.

    Kind regards,
    SinYen

  7. Jim says:

    Hi Chandoo,

    Quick question

    1) Is there a way to remove duplicates within each risk block?
    2) Is there a way to have the results in the chart update based on a filter or slicer?

    Thanks a lot

  8. Lebo says:

    Hi Chandoo,

    The risk map is a brilliant tool, and I wanted to the risk map to only show Open risks. How can I do that?

  9. Eric M says:

    Just found this today as I am making a risk matrix as well. I got the formula to work with this, where a risk score is above 30. Risk score = probability*impact*modifier.

    So this works flawlessly, ="- "&TEXTJOIN(CHAR(10)&"- ",TRUE,IF('Risk tracker'!G4:G27>=30,IF(Table1[Urgency]="Now",'Risk tracker'!A4:A27,""),""))

    I am trying to find a range now. Risk score in between 21-29. I tried using the AND function, but I couldnt get it to work. Is there anyway to get this formula to work with a range as mentioned above?

    • Chandoo says:

      Thanks Eric.

      You can't use AND() as it is not able to return arrays. You can try below formula.
      ="- "&TEXTJOIN(CHAR(10)&"- ",TRUE,IF(('Risk tracker'!G4:G27>=21)*('Risk tracker'!G4:G27<=29),IF(Table1[Urgency]="Now",'Risk tracker'!A4:A27,""),""))

  10. Michal says:

    Hello, this template is nice, thank you but im facing a problem when I need to find a range of impact. I cant figure out how..

    My actual form is "="• "&TEXTJOIN(CHAR(10)&"• ";TRUE;IF(Table1[Impact]=A8;Table1[Title];"");"")"

    Where A8 is number "1" so this formula finds everything with impact 1 and shows the titles.
    What I need to get is a range so,
    A8 is "1" and A9 is "2" and I need the formula to find all titles which impact is between 1 and 2.
    I tried the AND function and so on, nothing worked..

    Can you help me please?

    i tried everything in your video in the end i only get the bullet... please guide me through

    • masoud says:

      Sorted it... i was flash filling the other cells and it took other columns...

      i do have another question though... how can i use slicers to filter the content of the matrix, so that it'll show only the departments i select?

      slicer is working fine with the table, but the matrix still shows all the results

  12. JP says:

    Just want to thank you for this.

    It is awesome.
