Introduction to Excel VBA
Everyone has a language. My mother tongue is Telugu. But I also speak Hindi, English and Cutish (that is the language my 2 year old kids speak). You may be fluent in English, Spanish, French, German or Vietnamese.
Just like you and I, Excel has a language too, the one it can speak and understand. This language is called as VBA (Visual Basic for Applications).
When you tell instructions to Excel in this VBA language, Excel can do what you tell it. Thus enabling you to program Excel so that you can automate a boring report, format a big&ugly chart, clean-up some messy data or just play some random noises.
What is a Macro then?
A macro is nothing but a set of instructions you give Excel in the VBA language.
Writing Your First Macro
Note: If you are new computer programming, watch our Introduction to Programming Video before proceeding.
In order to write your first VBA program (or Macro), you need to know the language first. This is where Excel’s tape recorder will help us.
Tape Recorder?!?
Yes. Excel has a built-in tape recorder, that listens and records everything you do, in Excel’s own language, ie VBA.
Since we dont know any VBA, we will use this recorder to record our actions and then we will see recorded instructions (called as code in computer lingo) to understand how VBA looks like.
Our First VBA Macro – MakeMeRed()
Now that you understand some VBA jargon, lets move on and write our very first VBA Macro. The objective is simple. When we run this macro, it is going to color the currently selected cell with Red. Why red? Oh, red is pretty, bright and awesome – just like you.
This is how our macro is going to work when it is done.
6 steps to writing your first macro
If you do not see Developer ribbon, follow these instructions.
Excel 2007:
1. Click on Office button (top left)
2. Go to Excel Options
3. Go to Popular
4. Check “Show Developer Tab in Ribbon” (3rd Check box)
5. Click ok.
Excel 2010:
1. Click on File Menu (top left)
2. Go to Options
3. Select “Customize Ribbon”
4. Make sure “Developer tab” is checked in right side area
5. Click ok.
Step 1: Select any cell & start macro recorder
This is the easiest part. Just select any cell and go to Developer Ribbon & click on Record Macro button.
Step 2: Give a name to your Macro
Specify a name for your macro. I called mine MakeMeRed. You can choose whatever you want. Just make sure there are no spaces or special characters in the name (except underscore)
Click OK when done.
Step 3: Fill the current cell with red color
This is easy as eating pie. Just go to Home ribbon and fill red color in the current cell.
Step 4: Stop Recording
Now that you have done the only step in our macro, its time to stop Excel’s tape recorder. Go to Developer ribbon and hit “stop recording” button.
Step 5: Assign your Macro to a button
Now go to Insert ribbon and draw a nice rectangle. Then, put some text like “click me to fill red” in it.
Then right click on the rectangle shape and go to Assign Macro. And select the MakeMeRed macro from the list shown. Click ok.
Step 6: Go ahead and play with your first macro
That is all. Now, we have linked the rectangle shape to your macro. Whenever you click it, Excel would drop a bucket of red paint in the selected cell(s).
Go ahead and play with this little macro of ours.
Understanding the MakeMeRed Macro Code
Now that your first macro is working, lets peek behind the scenes and understand what VBA instructions are required to fill a cell with red.
To do this, right click on your current sheet name (bottom left) and click on View code option. (You can also press ALT+F11 to do the same).
This opens Visual Basic Editor – a place where you can view & edit various VBA instructions (macros, code) to get things done in Excel.
Understanding the Visual Basic Editor:
Before understanding the MakeMeRed macro, we need to be familiar with VBE (Visual Basic Editor). See this drawing to understand it.
Viewing the VBA behind MakeMeRed
- Select Module 1 from left side area of VBE (called as Project Explorer).
- Double click on it to open it in Editor Area (top right, big white rectangle)
- You can see the VBA Code behind MakeMeRed
If you have followed the instructions above, your code should look like this:
Sub MakeMeRed()
'
' MakeMeRed Macro
'
With Selection.Interior
.Pattern = xlSolid
.PatternColorIndex = xlAutomatic
.Color = 192
.TintAndShade = 0
.PatternTintAndShade = 0
End With
End Sub
So much for a simple red paint!!!
Well, what can I say, Excel is rather verbose when it is recording.
Understanding the MakeMeRed VBA Code
Lets go thru the entire Macro code one line at a time.
- Sub MakeMeRed(): This line tells Excel that we are writing a new set of instructions. The word SUB indicates that the following lines of VBA are a sub-procedure (or sub-routine). Which in computer lingo means, a group of related instructions meant to be followed together to do something meaningful. The Sub-procedure ends when Excel sees the phrase “End Sub”
- Lines starting with a single quote (‘): These lines are comments. Excel will ignore anything you write after a single quote. These are meant for your understanding.
- With Selection.Interior: While filling a cell with Red color may seem like one step for you and I, it is in fact a lot of steps for your computer. And whenever you need to do a lot of operations on the same thing (in this case, selected cell), it is better to bunch all of them. This is where the WITH statement comes in to picture. When Excel sees With Seletion.Interior, Excel is going to think, “ok, I am going to do all the next operations on Selected Cell’s Interior until I see End With line“
- Lines starting with .: These are the lines that tell Excel to format the cell’s interior. In this case, the most important line is .Color = 192 which is telling Excel to fill Red color in the selected cell.
- End With: This marks the end of With block.
- End Sub: This marks the end of our little macro named MakeMeRed().
Few Tips to understand this macro better:
Once you are examining the macro code, here are a few ways to learn better.
- Change something: You can change almost any line of the macro to see what happens. For example, change .color = 192 to .color = 62 and save. Then come back to Excel and run your macro to see what happens.
- Delete something: You can remove some of the lines in the macro to see what happens. Remove the line .PatternColorIndex = xlAutomatic and run again to see what happens.

Hi Chandoo,
To calculate time lapses in excel I usually use the DATEDIF function. Even though is undocumented by MS there is a great explanation of its use in Chip Pearson's site :
http://www.cpearson.com/excel/datedif.aspx
Is pretty easy to use and has great flexibility.
See you and keep Excelling!!!
Another great article, I will be linking to it on my blog.
Oliver:
Yes, I think that DATEDIFF do it better.
Great post! This a fantastic tutorial on calculating elapsed time in Excel that could be helpful even to a novice user. Keep up the useful tips!
Also, the Office community on Facebook could really benefit from you knowledge! Check it out at http://www.facebook.com/office

hi, Chandoo !!!
for elapsed time , we can use this unique formula either for hours, minutes or seconds : NOW()-A1)
but using respective special number formats
for hours : [h] ==> 46553
for minutes : [m] ==>2793212
for seconds : [s] ==> 167592763
We can also use mean duration for years (orbital period of the Earth around the Sun : i-e tropical year) which is : 365.25 days
and mean duration for month : 365.25/12 days
be Excelent !!!!
@Oliver... Thanks for the pointer to datediff(). I will update the post with information about this as well.
@Glen... thanks for the linklove 🙂
@Andy... Welcome. Thanks for telling us about the office community on FB.
@Modeste ... that is very cool. I will remember these formatting codes for an upcoming article on number formatting codes 🙂
Great tip Chandoo! I use the formula to calculate years elapsed all the time. It can seriously help save a ton of time with calculations. Also, NETWORKDAYS is one that helps and can seriously impress a boss. Keep up the great work here!
No problem! I will definitely be directing people with tough Excel questions to your blog. Keep up the great posts!

Hi,
always great posts and a good way to start my day
but regarding the elapsed time calculations: have you never noticed that there is a result difference between using =TODAY()-A1 and using =NETWORKDAYS(A1,TODAY())?
try it for A1= a Monday such as 21sep09 and "today" is e.g. a Thursday; you get 3 or 4 respectively as a result, depending on the formula used; this is because formula =networkdays() always includes both the startdate and the end date and not only the time between these 2.
This is easily corrected/compensated bij always adding a -1 to the =networkdays() formula because the majority of us will count startday as day 0 and then the result will be consistent across the different formulas.
However, you then get into trouble if you calculate the networkdays for a date further in the past and where either the start or end date falls in a weekend.
just thought to point this out as to me these formula's are not interchangeable just like that!
have a great day!
Paul
=DATEDIF([DOJ],TODAY(),"Y") & " Y, " & DATEDIF([DOJ],TODAY(),"YM") & " M, " & DATEDIF([DOJ],TODAY(),"MD") & " D"
This will fix your 30 Days problem
I calculated the time diff between two date+ times by subtracting 2 cells & custom formatted it to "d hh:mm" format.
E.g.
Cell A1 04-Jan-12 6:00 PM
Cell A2 05-Jan-12 4:45 PM
Cell A3 0 22:45 (formula: =A1-A2)
Wat shud i do 2 not display the "zero" values i.e. no. of days in this case is zero hence the cell shud display " 22: 45" and not "0: 22: 45".
@Amol
Try the Custom Format code:
[
<1] hh:mm ; [>=1] d “d” hh:mmHi Chandoo,
If possible to compute the interval of time and date in one column.
In column C I would like to compute the total days and hours . What formula ? Please help
Example.
Column A Column B
2/13/12 3:30 AM 2/14/12 12:00 AM
In referenc to Elapsed time in months
To calculate the elapsed time in months, we can use the formula =(NOW()-A1)/30. This returns the value in 30 day months.
I use to apply formula =ROUND((TODAY()-A1)/30,0). Today, I faced a peculiar situation, A1 has date 01-Mar-2009, and today being 01-Mar-2012, it should be 36 months, but it is showing 37 months!!
Any suggestions to avoid such errors?
Regards,
Prasad DN
All I want to do is add up a series of times and receive a reply that gives me a total. What I used to do was subtrace the end time from the start time and format the result as [hh]:mm but this doesn't seem to work anymore. How has Bill Gates confounded me?
@Pete
I use Excel 2010 and it still works
The times must be entered as times in the format hh:mm:ss or hh:mm without seconds
Adding up times is as simple as =Sum(Range) or =Sum(A2:A10)
then using a Custom Number format as you have mentioned [h]:mm
If this isn't working, 2 ideas
1. Check your times are times and not text
2. Can you share your data or file with us?
My hospital tracks times from patient arrival to various procedures or treatments. When those times cross over midnight, the regular formulas (2nd time minus first time) don’t work because the result is negative and Excel (2007) won’t show a negative number in time format.
I couldn’t find a solution here (chandoo.org) but found one elsewhere that worked and it’s very simple. I would like to share it.
Assuming 1st time in A1 (column for patient arrival time) (11:00 PM), and 2nd time in B1 (column for x-ray given) (12:30 AM)). Should be 1:30 elapsed time.
=B1-A1+(B1<A1) [This comparison is the key to the solution.]
=12:30 AM – 11:00 PM + (12:30 AM < 11:00 PM)
=0.0208 – 0.9583 + (True)
=-0.9375 + (1) [This is the key! If it is false, Excel adds 0. If it’s true, Excel adds 1 and that is what corrects the negative number. Now Excel can interpret the number as a time.]
=0.0625
Converted to hh:mm = 1:30
I wrapped this formula inside an IFERROR one to alert my data entry person if she messed up and applied it to lots of different columns and it has worked wonderfully. No more complaints from the data entry person who just plugs in times from medical charts.
Very interesting solution. Thank you so much for sharing it with all of us.
HI,
I am working on a Xl application..
I want to capture time between two clicks.
Ex, in my application during run somewhere I press OK button and then I click Cancel.. I want to measure time between these two clicks... Is it possible??
Pls help on this...
@shashidhar
The answer is Yes
You will have to add an appropriate VBA event to start and stop a timer.
There are techniques which can time to the millisecond so maybe look those up on the net
WOW!!!!!! I truly love your excel time format program! WHOOOO! I am very interested in how the time formats "update" (manually on a physical keyboard) that "updates" the time into its respective decimal time formats, such as:
YYYY.yyyy, HH.hhh, etc...
How do those formulas or equations work if not in Excel mode? Example: TI calculators, Word, or any other computer language programming? Just wanted to see how it works. E-mail me at Ultra64848689Ti@gmail.com.
Thanks again for an EXCELLENT Excel program into decimal time formats!
Here's an idea: how about creating an APP for iOS and Android? Just wanted to point that out. =-D
Regarding the elapsed time in months:
I made this function to determine the time elapsed since a date using the number of days in each respective month. It's a simple subtraction and I think it works very well:((Year Today-Year A1)*12++(Month Today - Month A1)+(Day Today/Days in Month Today)-Days A1/Days in month A1)
Here's the function:
=((YEAR(TODAY())-YEAR(A1))*12)+(MONTH(TODAY())-MONTH(A1))+(DAY(TODAY())/DAY(DATE(YEAR(TODAY()),MONTH(TODAY())+1,0))-DAY(A1)/DAY(DATE(YEAR(A1),MONTH(A1)+1,0)))
Have a Merry Christmas everyone!!
I need the ability to calculate how much progress we have made between two dates and I want to represent that as a percentage.
I am thinking this would be a combination of today, networkdays & dividing the days elapsed vs the total days. Then it should be as easy as formatting my cell. Any help would be greatly appreciated.
@Christian
Your correct
dates are just numbers and so you can use simple math to derive the percentage
=(Date Now-Start Date)/(End date-Start date)
that will give you a number between 0 and 1
which you can format as a %'age
is there a way out to calculate the productivity for an employee
The day start is at 08:00 and day end is 20:00
The start date / time is recorded and end date / time is recorded
I want to calculate the timelapse taking into consideration the day begin and dayend time.
If the work begins and ends the same day, a simple formula b1-a1 would compute the productivity.
But if the process remains incomplete and is carried over to the next day, then timelines to be computed accordingly
to clarify,
if start time of an activity is 03/15/2015 18:00 hrs and end time is 03/16/2015 11:00 hrs, then the resultant formula should be 5 hrs (ie 18:00 to 20:00 hrs on day1 + 08:00 to 11:00 hrs on day2) ie 2+3
please guide.
Venkatesh, try (b1-a1)-0.5
This will subtract the fixed amount of time between shifts, 12 hours. If the time between shifts varies, then you could reference other cells that contain the variables.
Please help. when I use the networking days formula I get a date (2-may-00) I want actual number of days. I managing projects and I need to know how many days have passed since we received a project to the current date. Please help Thanks
@Aria: Just format the cell as general or number. that will fix the problem.
You rock! I looked at 17 other sites and they all did not work. Yours did. Thanks!
Hi folks ...
calculating age in years , months and days
=text(now()-a1,"yy")&" y " &text(now()-a1,"mm")-1 &" m "&text(now()-a1,"dd") & " d"
Hi, the Elapsed time in days [ =TODAY()-A1 ] works great however, if I do not have a date in A1, it shows 42157. Anyway to get it to display 0 or a Null value?
@Dan
=If(A1="",0,TODAY()-A1)
I get #NAME? and the formula does not work.
Hi Chandoo,
This might be a challenge - I am looking to calculate elapsed time between two columns
Start date Complete date
9/9/2015 7:21 10/2/2015 11:01
I need to take into account the following:
1) The employee works 7:00-3:15 pm each day
2) Std Work hours are 7hrs 45 min each day
3) Need to take into account all holidays in between start and end date
4) Work week is Mon through Friday.
Can you help?
Thanks!
Hi, i have a certain name (wilium) in column A and against this name i have 2 option, 1 Done and 2 Inprogress. i want that i count done again wilium and count inprogress against wilium separately. which formula will work for it??

Year, month, day results for DoB.
The formulas I have found on the net and the datedif function do not work. This is what I came up with using a Microsoft support paper dated April 1997 with some modifications:
IF(OR(A2>$A$1,ISBLANK(A2)),"",IF(YEAR($A$1)=YEAR(A2),0,IF(MONTH($A$1)>=MONTH(A2),YEAR($A$1)-YEAR(A2),YEAR($A$1)-YEAR(A2)-1))&" years "&MONTH($A$1)-MONTH(A2)+IF(AND(MONTH($A$1)<=MONTH(A2),DAY($A$1)<DAY(A2)),11,IF(AND(MONTH($A$1)=DAY(A2)),12,IF(AND(MONTH($A$1)>MONTH(A2),DAY($A$1)=DAY(A2),ABS(DAY($A$1)-DAY(A2)),DAY(EOMONTH(A2,0))-DAY(A2)+DAY($A$1))&" days")
Check it out...
Hi, Augustin
what about :
calculating age in years , months and days
=YEAR(NOW()-DoB)-1900 & " y " & MONTH(NOW()-DoB)-1 & " m " & DAY(NOW()-DoB) & " d"
Hi Chandoo,
I am looking for help with the elapse time formula. I have a recruitment tracking sheet where we track the number of days the positions are opened, and when they are finally closed.
The opened positions will have a running turnaround time (TAT) formula and I am using this formula:
=NETWORKDAYS (start_date, TODAY (), Holidays2018)
Now, without disrupting the running TAT formula, how do I then get the TAT to stop when we have a final end date? All the information below is row:
- start_date --> Cell A
- TODAY () --> cell B
- end_date --> Cell C
Hope you are able to help. Thanks!
Interesting question. Try this:
Thank you for this helpful article. I was trying for days now to figure it out. Now the only issue I have is that if I do not have a value inputed for =TODAY()-[@[Date Precured]] Date Precured then it shows 44055. How can I get it to leave it blank if there is no data? Thanks again!!!
