Greetings and salutations, my fellow VBA-fearin’ congregation. Evangelizin’ Jeff here, spreading the good word about everlastin’ VBA serenity. You may remember me from mah preeeevious sermons such as Tables, PivotTables, and Macros: music to your ears and Big trouble in little spreadsheet. Well today, I’m going to praise the work of a high-yah pow-wah.
Our most pious Brother Jon Peltier (who’s fine presence is to mah left) broke his vow of silence over at the PeltierTech monastery to make a most inspirin’ observation during his recent confession Highlight a Specific Data Label in an Excel Chart:
Because I’ve been doing a lot of coding lately, my first thought was an approach using VBA. Then of course I came to my senses, and worked out a non-programmatic approach.
If possible, it’s usually advantageous not to rely on VBA for such tasks.
Hallelujah, brother!
My visionary brother is right: if there’s one rule of VBA that you should religiously observe, it’s to let the application be the application, where ee-fishin’ tah do so. A whiles back, I jokingly spoke it alike this:
The serenity prayer for Excel:
Lord grant me the VBA skills to automate the things I cannot easily change; the knowledge to leverage fully off the inbuilt features that I can; and the wisdom to know the difference.
(And I particularly chuckled at Excel Ninja BobHC’s response: You been on them tablets again.)
This sentiment is echoed in the commandments given us in Professional Excel Development (written by those latter-day-saints Bovey, Wallentin, Bullen, and Green):
This Good Book evangelizes that Excel developers “…shalt be divided into five different categories”:
- Basic Excel users, whom generally use Excel for fairly simple tasks, but as their exposure to Excel grows, so does the complexity of their worksheets and use of complex worksheet functions, PivotTables, and Charts.
- Power Users, whom have a broad understanding of Excel’s functionality, and occasionally use snippets of VBA from the Net or via the Macro Recorder, but their code tends to be messy, slow, and hard to maintain.
- VBA Developers, whom make extensive use of VBA – perhaps too much…to the point that they tend to use VBA to tackle practically every problem.
- Excel Developers, whom realize that the most efficient and maintainable applications are those that make the most of Excel’s built-in functionality, augmented by VBA where appropriate.
- Professional Excel Developers, whom know more languages than your typical Babel Fish.
That leap from VBA developer to Excel developer is worth striving for. (Don’t bother striving to be a Professional Excel Developer…they are so nerdy that they get about as many dates as your typical cloistered monk or nun). Unfortunately gaining the wisdom to jump from that third class to the forth one ain’t easy, and dedicated sermons on this matter are few and veryfar between.
Far too often the likes of yours truly are often so focused on leading you not into temptation and instead down a righteous path, that we simply never take the flock anywhere near enough to temptation so that we might cautiously peer at it from a safe distance and say in our most solemn and hushed tone “That way surely leads to hellfire, damnation, and eternal recalculation”. No siree, I’m afraid we usually opt instead to simply get the flock away from there.
However, help is at hand, sinners. Forums such as our very own Chandoo.org/forum are a great place to get guidance on such spirited matters…particularly if you ask the right question, such as “What is the best way to achieve X using Excel version Y”. But you’ll need to ask an open question based around what you are trying to accomplish, rather than being overly focused on how you are trying to accomplish it.
For instance, if you ask “How can I efficiently achieve X with VBA“ then that is all you will get…answers about the most efficient way to do it within the confines of the particular tool you have specified. Which will often not be the most efficient way. In fact, I’ve lost count of the number of times where someone has asked for a formula or VBA solution to some devilishly complicated problem – and got something devilishly complicated formula or code as a result – when a mere PivotTable would have sufficed. Or when some very simple Structured Query Language (SQL) via the in-built (but antiquated) Microsoft Query interface would have nailed it.
[Aside: SQL is basically a database language use to perform the database equivalent of lookups and to crunch numbers, or to conditionally join large datasets based on multiple complex conditions. SQL can be directly leveraged by Excel with minimal programming. Heck, you can use SQL to do stuff with NO programming whatsoever via Microsoft Query – a handy (if ancient) little interface bundled into Excel that will look familiar to any Access users. For an excellent Excel-centric introduction to SQL, read Craig Hatmaker’s amazing Beyond Excel: VBA and Database Manipulation blog. Chandoo also has a great guest post by Vijay – Using Excel As Your Database – on this subject. Ignore all the naysayers and unbelievers in the comments who say “Excel shalt not be used a database” for they know not what the point is. Which is that yea Excel doeth speak in SQL tongues at a pinch, and SQL is pure salvation when it comes to manipulating data, be it Big Data, Small Data, or Somewhere-In-Between data.]
Not to mention the miracles even a layperson can perform if they have the almighty Excel 2010 and PowerPivot installed. Or Excel 2013’s Data Model, which lets you mash up data from Excel Tables and serve them up directly as PivotTables with not a VLOOKUP or Macro in sight.
The end of Excel ain’t nigh…
Every release, Excel gets stronger and stronger. Excel 2010 offered us sinners significant improvements over previous versions…giving us things like Slicers and the free PowerPivot add-in. Excel 2013 takes a giant leap forward in allowing us to leverage off of inbuilt functionality to do things that we would otherwise require tons of complex code and complex formulas to achieve. Had Excel 2013 been launched 10 years ago, I simply wouldn’t need to have been a-preaching VBA and SQL to as many unbelievers as I have. If we keep abreast of these changes, then as the functionality of Excel ramps ever up, our code can ramp down accordingly.
The bottom line here is this: if thou strive to be a really good Excel developer then thou best get to know what’s behind just about every nook and cranny of the Excel application itself. Particularly the newly prophesied ones (yea the power of PowerPivot compels you,according to that dark preacher Mike Alexander). So go and explore all those mysterious things on the ribbon. You don’t have to master all of them…but it sure does help if you have an inkling of what they all do. Not just the obvious things like Tables and PivotTables, but the more mysterious ones like Slicers, Data Validation, and What-If-Analyis. And also the completely hidden ones like Goto Special. Not only do all those things do things natively that would require many Shekels of VBA code to replicate, but most are completely addressable from VBA to boot. Meaning an Excel Developer can simply say “Excel – do that thing with this data“.
Before you try to bend Excel to your complete command, study it well. No matter how much you want to jump right in tinker with Excel’s very soul, don’t discount what’s effectively printed on the outside of the box. If you do, you’re just another lazy devil writing hellish code.
Feel free to leave your own theological questions and musings in the confessional box below. Unless it’s to say that you don’t like Pokey LaFarge. Keep that to yourself. Because I love ’em. Saw them live in Wellington a couple of weeks back. Definitely worth checking out if they come to a town near you.

Hi Chandoo,
Since this article was for Dates, below are 2 easy ones to calculate the Start and End of Month. (without using the EOMONTH formula as available in Analysis Toolpak).
In Cell A1, put any date
then in the cell where you would want the Start of Month put the below formula
1. Start of the Month
=DATE(YEAR(A1),MONTH(A1),1)
2. End of Month
=DATE(YEAR(A1),MONTH(A1)+1,0)
Hope this would help a lot who were dependant of EOMONTH..
cheers
~Vijay
@Vijay: That is an awesome tip. Thank you so much for sharing it with all of us.
Perfect
Why not use the EOMONTH formula?

Thanks for any help....
@Glenn: you can try a user defined function if the information you want to gather can be derived only from the 2 dates entered. You can write a macro, if you need to refer to other ranges in the workbook to gather the info based on the dates entered. I am not sure what you meant by "go find the info for that range". May be if you tell what you are trying to find, I can suggest the approach for writing a macro...

=DATEDIF(START_DATE,END_DATE,"Y") - gives you the years
=DATEDIF(START_DATE,END_DATE,"YM") - remaining months

Help please... I have two dates eg: 1/8/10 - 10/8/10 and i would like to know the number of Fridays and Mondays in any given period
Ray
Try the following user defined function:
===
Function NoMonFri(uStart As Range, uEnd As Range, Optional uType As Integer) As Double
Count = 0
For i = uStart To uEnd Step 1
If Weekday(i) = 2 Or Weekday(i) = 6 Then Count = Count + 1
Next i
If uType = 1 Then
If Weekday(uStart) = 2 Or Weekday(uStart) = 6 Then Count = Count - 1
If Weekday(uEnd) = 2 Or Weekday(uEnd) = 6 Then Count = Count - 1
End If
NoMonFri = Count
End Function
====
Copy the above into a Code Module
To use just enter
=NoMonFri(A1, A2) or
=NoMonFri(A1, A2,1)
Where A1 & A2 are the Start and End Dates (inclusively)
The use of the optional 1 will Exclude the Start and End dates
@Ray... You can also do this using SUMPRODUCT (ahem)
Assuming first date is in C6 and second date is in C7,
=SUMPRODUCT(--(MOD(WEEKDAY(ROW(INDIRECT(C6&":"&C7)),2),4)=1))
Will give you the number of Mondays and Fridays between C6 and C7 (including both days)
Also, checkout NETWORKINGDAYS() UDF for more complicated counting... http://chandoo.org/wp/2009/06/09/networkingdays/

Hello Chandoo,
How to convert no into time. for ex: 3600(In Seconds) into 1:00:00
Thanks,
Chandra Shekar B
@Chandra
Times are a fraction of 1
So 6am is 0.25
12 noon is 0.5
6pm is 0.75
So convert hrs and mins to a fraction of 24 hrs
1 Hr = 1/24
3600 seconds = 3600/(24*3600)
etc

Hi Chandoo,
When discussing about time.. I have one question too. Basically, I have one sheet in which we enter "Shift IN" & "Shift OUT" times as "hh:mm" format in A and B columns and next columns C & D pulls the scheduled and present count of agents from other sheet by VLOOKUP-ing times as
IN time (hh:mm) - OUT Time (hh:mm). For eg; 03:30 - 12:30
Columns A and B have been validated to accept only values between 00:00~23:30 (half hour intervals). and when pasting data, the values are usually accepted and I don't get any errors of validation.
But, when performing vlookup to get the number of scheduled agents say as of the time interval 03:30, I get an #N/A error. I have confirmed ranges are all fine, but what I found is that the time although shows same but they are actually of different days. Say for eg;
41023.39583 gives 9:30
41024.39583 gives 9:30 too..
Validation is accepted as time is same, and it works fine if I select the time interval from the validation list. So, was wondering, if I can select the same interval from the list using VBA.. so that whatever the time intervals gets updated, I just need to run a macro to automatically select the interval from the validation list.. I have come across that we can use Cell.Validation.Formula1 in some manner to get the item from list.. but it would take the number of the item in the list.. wondered if I could get the item through text. Any ideas to accomplish this task?
Regards,
Avinash

Please i need an advise ASAP i have been using this statement and it cant help
if(and(c1>=a1:a144,c1<=b1:b144),"yes","no"))
and it just works for the first 2 values c1, c2 and doesn't fit for the others.
the case is i have more than one event at the same video and i need to confirm that no event was taken unless it is between start and end.
here are some samples:
Start dtime End Dtime Event Dtime
16/09/2013 22:13:34 16/09/2013 22:14:18 16/09/2013 22:13:38
16/09/2013 22:15:57 16/09/2013 22:24:30 16/09/2013 22:16:02
16/09/2013 22:24:30 16/09/2013 22:33:49 16/09/2013 22:17:32
16/09/2013 22:33:53 16/09/2013 22:35:05 16/09/2013 22:19:02
16/09/2013 22:35:05 16/09/2013 22:39:57 16/09/2013 22:20:02
So as you can see there are more than one event between one start and end dtimes

It is poor practice to store multiple records in one cell

The cells must be formatted as text they cannot be formatted as date. I do not want to have to macro-enable my workbooks, There must be a setting in the registry to set this?

I need it to be dates so I can then create pivot tables and charts from the data.

The most important thing is if you do any calculations you need to be careful, given the vagaries of floating point math.
e.g. depending on the day you choose, 4pm minus 3pm may be less than, equal to, or greater than one hour.

Wow! Came here from India's top blogs and this is superb! For some reason, dates have always confounded me in Excel and this was exactly what I needed - esp the section on adding and subtracting dates. Thanks a ton!
Hi,
I have a mixed combinations of date format in one column i.e. 'dd/mm/yy' and 'mm/dd/yy'. How do I make them all in the same format, either all in 'dd/mm/yy' format, or all 'mm/dd/yy' format? Thanks in advance!

Hi Chandoo,
Need a small help to build a formula where we can show the date of Monday i.e. start of week date from time stamp for eg "3/2/2022 9:21 PM" or either from "Week 10'2022" where Week is for entire year i.e till week 52/53 and "2022" represents the year
Thanks in advance
Best
