- My Top 10 Tips for Mastering VBA & Excel Macros
In the part 5 of our VBA Crash Course, let me share you my tips for mastering Excel VBA.
A warning before jumping in to the tips: I am not a VBA expert. I am a learner, just like you. I find VBA quite interesting language to learn and explore. These tips are based on what I have learned writing VBA (and VB code) in the last 12 years.
Tips for using & mastering VBA in short term:
#1 Think Thru before Coding
The best way to solve even a very complex problem is to think thru. Next time, when you are about to automate that report or clean some imported data using VBA, just write the logic down on a paper. See and understand various aspects of the problem. The solution becomes clear to you. It has worked for me and it works for you too.

#2 Use the Recorder
Excel’s built in Macro recorder is a great way to learn about new objects and ways to deal with them. I use it all the time to record parts of my code and then customize the output. Just keep in mind that macro recorder does not produce the best or complete code all the time. But it gives you a damn good idea about how to write code for a set of actions.

#3 Use Immediate Window
Excel VBE has a powerful feature called as Immediate window. Think of this like a sandbox. You can write almost any VBA statements here and get quick results. For example, Open VBE (ALT+F11 in Excel) and go to Immediate window.
- Type ?Activecell.Value
- Press Enter
- And you will see the current cell’s value printed in immediate window
Here is a quick demo of immediate window.
#4 Debug.Print is your Friend
There are 3 things you cannot avoid in life
- your 2 year old daughter thinking it would be fun to throw a stone on your car
- your baby boy running and sitting in your lap suddenly making the hot coffee spill on you
- and of course bugs in your code
Bug is a fancy name given to the situation when your code is not doing what it is supposed to do.
But why?!? Well, we don’t know why unless we examine. And this is where Debug.Print can come handy. In below example, you would see the values of all tasks in the immediate window as your program runs.
#5 There is a method for that!
Just like Apple says There is an App for that!, may be Microsoft should say There is a Method for that! about VBA. I say this because VBA comes with a lot of methods and functions to do lots of things. If you are thinking of writing your own code to reverse some text, split something based on a delimiter, find the intersection of 2 ranges or run something after 10 seconds, may be you should before writing your code. Because, my dear, there is a method for that.
Whenever you feel like you are writing code for a problem that is already solved several times, chances are there is some built-in method or object for that. So just search.
Tips for Using & Mastering VBA in Long-term
While the above tips are good for solving your immediate problems, we should always aim for continuous improvement. Here are my top tips for keeping your VBA in shape.
#6 Break Your Work in to Smaller Chunks
No matter how complex your work situation or problem might be, chances are, it is made up of several smaller problems. So break things in to smaller chunks. This coding technique is called as modularization. Modularization has several advantages:
- Reuse: Once you break a big program to smaller parts, you can reuse a smaller part in several places or in other projects.
- Testable: Smaller code fragments are easy to test and debug.
- Maintainable: You can maintain smaller parts easily. You can upgrade them once you get a better version of Excel without breaking much.
#7 Build Iteratively
Rome is not built in one day, so is your buildRome() macro. Whenever you are attempting to automate a whole department’s work, take a step back and see what is the smallest (but most useful) feature you can have. Implement it and then add new features iteratively. That way, your turn-around time is improved, you look pretty in front of your boss and you feel in control of things.
Iterative development also lets you stop whenever you want and you would still have some working piece of code.
#8 Keep a Good Reference Handy
If you are going to use VBA quite often, then invest in a good reference. I suggest John Walkenbach’s Excel 2010 Power Programming if you are looking for one. Good reference books have lots of information and tips buried in them. For example, I keep Excel 2010 Power Programming book on my desk all the time and refer to it whenever I feel like not doing any work. I always learn something new.
#9 Take up Challenges
“Computers are like bicycles for our mind” said Steve Jobs. I am not sure if hours I put on facebook, twitter and gmail are keeping my mind fit. But any time I invest on programming is worth every second. I feel very sharp, excited and stoked when I solve a tricky problem using a computer program (be it VBA, an Excel Formula or php or anything else).
I think if you want to be good in VBA or Excel, then take up challenging work. Try to automate a report that you (or your team) produce using VBA, Try to simplify a formula or improve a chart.
If you are looking for fresh challenges, then look at our forums. We get dozens of interesting questions everyday.
#10 Use VBA only when you need it
Once you start learning VBA, it is natural to feel excited about the possibilities you have. But keep in mind that overusing it can complicate your work.
My suggestion: Use Excel’s native features as much as possible. Excel has several built in features to solve various day to day problems (conditional formatting, pivot tables, formulas, data validation, form controls to name a few). Only when you feel that there is no easy way to use Excel alone to solve a problem, go for VBA.
Example: Recently, I showed you all how to split text on new line using VBA. I did that because I thought there was no way to do it using Excel’s built in text-to-columns utility. Well, I was wrong. As Debra proved in the comments,
Chandoo, if you want to do this in the Text To Columns dialog box,
Select Delimited, then check “Other”
In the box beside Other, press the Alt key, and type (using the number keypad): 0010That should separate the text on the line break character.
So if you feel like there is no way to do something in Excel without resorting to VBA, well, just keep looking, because there might be a way.

Any chance on a 2016 calendar?
Afternoon,
I have one similar calander that I added conditional formatting to so that I could highlight any planned factory holidays. I think i "borrowed" the formula from another calander so I won't post it here.
I also added week numbers to it using the formula =WEEKNUM(MAX(C6:I6)) Where C6:I6 is the range of dates in that give week. It works fine on most of the months but return strange values on other months (Week 6 in October?) I can't see any logic behind why it does this.
Any suggestions for an alternative formula to give the week numbers?
Regards,
William
Hi Chandoo,
I've added a new feature on your spreadsheet.
This control can be useful for all the sheets where you need to check dates.
Cheers

Hi Chandoo,
Nice calendar.
Till now whichever calendar I saw in Excel, it contained only the outline sheet.
Good to see monthly views and the mini view too.
Liked the mini view much. 🙂
-Nimesh
@William: This weeknum may be because the input dates to max are not properly formatting as excel dates.
Good tip on the conditional formatting and holidays btw...
@Migueal: Now that is super awesome. This is the reason why I love to blog. Readers will always one up me with such cool alternatives. Thank you for sharing this with us.
@Nimesh: You are welcome 🙂
is it possible to get the Notes section on the outline page to display the notes added to the month page for a specific date?
So if you add thing for January 2nd, and then select January 2nd those notes appear on the outline page
@Shish... You can do that using some formula magic. I would not recommend pushing excel to that as outlook / google calendar / icalc etc. do exactly that much more elegantly.

Happy christmas to all of you!
This is really awesome. The nicest calender I've seen for Excel. I also like Miguels version of the sheet.
Just one "feature" is missing to me. As I live in Germany - where weeks start on Monday - I'd like to change this. Could someone please give me a hint how to do this?
Thanks in advance
Jörg
Hi Chandoo, I’ve added some new features on your spreadsheet with your permission.
Check it here:
http://cid-6b219f16da7128e3.skydrive.live.com/self.aspx/.Public/Calendar%5E_Pedro.xlsm
Miguel, this calendar is translated to Spanish language.
Jörg, this new approach allows us to start weeks on Monday.
Also it's possible to start weeks on Sunday if you enable Excel macros and push the arrows.
Best Regards,
Pedro.
@Pedro.. superb stuff.. thanks for sharing the file with all of us.
Hi Chandoo, for dates before March 1, 1900 our calendars are wrong.
In Microsoft Excel, DATE, EOMONTH, WEEKDAY functions return an incorrect result between Monday, January 1, 1900 and Wednesday, February 28, 1900.
See this page: http://support.microsoft.com/kb/214326/en-us/
Microsoft Excel incorrectly assumes that the year 1900 is a leap year in all Excel versions.
That's the reason why our calendar versions only work from March, 1, 1900 until December, 31, 9999.
Your comments are welcome.
Pedro.
@Pedro.. Thanks for pointing that out. wow... This reminds me of the Joel Spolsky's first BillG review - http://www.joelonsoftware.com/items/2006/06/16.html (read it, I am sure you would love it.) when Bill out of blue asks about date time implementations for VBA (which Joel is the program manager for...)
Thanks for sharing the URL too... Here is a specially made, chocolate sprinkled, extra fluffy donut for you 🙂
Hi Chandoo, thanks a lot for the donut but I prefer it without chocolate!
Always it's good to know a little history of Excel.
The Joel Spolsky’s last BillG Excel review was about the "Hall of Tortured Souls"
(See this Excel 95 Easter Egg here: http://www.eeggs.com/items/719.html)
Do not miss the humor!
@Chandoo.. I just return with a new calendar version.

Please, I need help!
I like all calendar from Pedro, thank you for them. Let me show my problem:
I have 2 excel cells (for example AE12 and AE13) which mean the starting and the ending date of my duty. I need a macro to insert sheets with label YEAR. MONTH (for example 2010. August or similar) with the proper datas between the two dates. Is it possible?
Thank you for reading me and sorry about my terribel english! 🙂
Hello Pedro,
Thanks so much for the modified calendar template. I love the extra functionality you added. Is there any way you could upload an unlocked version? I wanted to change some of the comments and data validation so I could use it for one of my applications.
As for feedback on potential improvements, with all the additions you made the file runs pretty slow. I'm sure this has to do with all the interconnectivity between the various tabs, but if there is a way to use less memory via more efficient formulas or something else I think this would make it easier to use. I have a brand new computer and with it running alone the response was pretty slow. One of the changes I'm making is changing the order of the months to match my company's fiscal year, so maybe something to automate a change like that could be useful.
Cheers,
Peter
Peter, my calendars are unlocked but you need Excel 2007 and 2010 versions to open them.
Now I return with a new Programmable Task Calendar:
http://cid-6b219f16da7128e3.office.live.com/view.aspx/.Public/Calendario%20de%20Tareas.xlsx
Wath an introductory video here:
http://pedrowave.blogspot.com/2010/10/programmable-task-calendar.html
This new calendar allows to select the start month to match the school and fiscal year.
This is great stuff Chandoo and company
Wanted to know if someone had built something similar
I need to store one Excel Sheet on this calendar that has all the holidays
US Holidays appear in RED
UK Holidays appear in Blue
Meetings appear in Green
Submissions appear in Orange
Is there a way I can store the list in a separate worksheet and all the calendars get updated with this?
Thanks
