Sometime during the 2nd half of 2013, I finished 10 years of Excel usage. In the last 10 years, I completed my studies, got my first job, married, had kids, visited 15 different countries, quit my job to start a business, bought first car, first house, made dozens of new friends, read 100s of books, wrote a book and learned 1000s of new things. And all along, Excel stayed a true companion. Right from MBA entrance exam preparation in 2003 to making my summer internship project reports in 2005 to planning my wedding expenses in 2007 to getting a promotion in 2009 to planning my kids feeding schedule in 2010 to running a successful business in 2014, Excel helped me in every step.
So today, I want to tell you the top 10 things I learned using Excel in last decade. Grab a hot cup of coffee, buckle your belts and get ready for time travel.
Late 2003 & 2004: Using Excel to track exam prep & making sales reports using Excel + Java!!!
During 2003, I got my first job as software engineer. I used work more roughly 10 hours a day + 2 hour commute. This left me with very little time to prepare for MBA entrance exams. So I used Excel to plan my time efficiently, track my preparation progress, mistakes made in mock examinations and test scores. Everyday before sleep I used to review the Excel workbook to understand how I can improve, where I am struggling. If any of you remember the Active Desktop feature of Windows 2000, I used it to show the Excel workbook as my desktop wallpaper so that it was never out of sight.
Although the workbook was not very sophisticated, it helped me greatly in securing admission to one of the best MBA colleges in India.
During my work as software engineer, I got an interesting challenge. I was asked to create Excel based sales reports from Java / JSP code. Back then, there is no API to directly create Excel files from Java. So I used Apache’s POI HSSF (Poor Obfuscation Interface – Horrible Spread Sheet Format) to create a Java class called as ExcelBridge. This can take raw data (from MySQL) and convert it in to Sales report Excel workbook. Last heard, my company & their clients are still using ExcelBridge to publish sales reports.
Although ExcelBridge is a complex piece of work, I learned little about Excel thru it. I had a colleague (Roja), who knew how to format Excel files, how to use VB Script, so she helped me with Excel part while I focused on Java & MySQL.
Things learned: coloring cells, using Excel to track data.
2005: IF()
Later when I joined B-School, I had to learn how to use formulas like IF() to model real world situations. And boy oh boy, that proved to be a very difficult experience. I still remember that one afternoon when I spent more than 2 hours trying to debug the IF() formula.
Later in 2005 during my summer internship, I learned how to use Pivot tables to analyze survey data. Although I made the reports, I did not have a clue as to what pivot tables were doing.
A part of Excel report made during my summer internship. Don’t ask me what it says.
Things learned: IF formula and few others, very little bit of VBA coding
2006: Analyzing data
By July 2006, I started working as business analyst with a leading IT company in India. During my first 4 months, all I was doing is analyzing data in Excel and making presentations. This was a very intense learning experience. During one of the assignments, I was analyzing annual reports of 70 Fortune 500 insurance companies using Excel. Lots of numbers, text and details.
It became obvious that to shine as a business analyst I must be very good in Excel & Power Point. So I used make Excel files modeling many problems from my personal life, like planning my retirement. Here is one such thing I made in 2006.
Things learned: formulas, charting concepts, creating & maintaining large workbooks.
2007: Modeling, more analysis
During 2007, one of the work projects required that I visit Hong Kong to meet a Chinese health insurance company and understand their claims process. If you have ever had a health insurance claim, you know what complex cobweb it is. Not only I had to understand that, but I had to explain it in Excel (and Word) so our coding team can create programs to improve the claims process. This made me understand the true power of Excel. My colleague (Eldhose) & I created elaborate models to explain the claims process, classification of diseases, treatment procedures and more.
Things learned: how to use data validation & form controls can help in user interactivity and controlling formulas.
2008: Gantt Charts and Conditional Formatting
For a few weeks in early 2008, I became a makeshift project manager. One of the first things I had to do was to create a plan and share with it our client. I quickly whipped up a Gantt chart using Excel. Our clients loved the plan that they asked me to continue full-time.
2008 is also the year I started writing more often about Excel on Chandoo.org. Until then, Chandoo.org used to be a mixed bag with lots of personal stories, rants and observations.
This Gantt chart almost got me a promotion.
Things learned: using features like formulas & conditional formatting to make gantt charts.
2009: SUMPRODUCT, Tables, Charts & Reports
By 2009, I was managing a small team of business analysts and started working with another insurance giant in Sweden. Most of my work involved reporting, analysis and meetings. Naturally, Excel became my ally as I was making charts, reports, trackers and presentations almost everyday. Whatever I was learning, I used to post it on Chandoo.org (I still do.) SUMPRODUCT also became my best friend as I had to calculate numbers based on various criteria. And Tables became the greatest ally. I used them everywhere.
Things learned: SUMPRODUCT, Excel Tables, chart customization, tweaking and building better charts.
2010: Dashboards
Although I started learning about Dashboards in 2008 (thanks to my good friend Robert’s excellent KPI dashboard articles), by 2010 I was making them more often. New features in Excel 2010 like slicers, sparklines helped me even more.
In 2010, I quit my job finally to work on Chandoo.org full time. Naturally I started using Excel to manage my business. 2010 is also the start of a really intense and rapid learning phases in my life. I learned new concepts and usages of Excel almost every week since then. Since I do not want to keep this knowledge, I started Excel School program. Now thousands of people all over the world are Excel pros, thanks to this course.
An example dashboard you will learn in Excel School
Things learned: Creating and formatting better looking dashboards
2011: VBA & Macros
Although I have been coding in VB since 1999, I have not used it with Excel very much until 2011. So during late 2010, I started brushing up my VBA concepts and by early 2011 I was building small apps and cool things with VBA. With the confidence I gained in VBA, I launched our VBA Classes so that many more of you can become awesome in VBA & Macros.
One of the many VBA apps I built
Things learned: VBA, Macros, Excel 2010 slicers
2012: Improving my analysis skills
In 2012, I focused on improving my analytical skills. I spent a lot of time using pivot tables, formulas and charts to analyze my own business data, examples shared by readers on Chandoo.org. Some of this can be seen in customer service dashboard, analyzing 20,000 comments, Usain Bolt vs. Rest and Excel salary survey dashboards.
Things learned: Advanced data analysis, dashboard special effects thru VBA
2013: PowerPivot
During late 2012, I started learning PowerPivot. Although, PowerPivot has been around for a few years, I never used it well until then. I bought a few books and by early 2013, I became proficient in PowerPivot, DAX and creating awesome dashboards with it. I took all these beautiful ideas and packaged them in to my online Power Pivot classes, which helped more than thousand people become awesome.
An example Power Pivot dashboard we discuss in Power Pivot class
Things learned: PowerPivot, DAX, Data Explorer (now Power Query).
So what is in store for 2014?
I am really excited about 2014. This year, I am hoping to dip my feet in to Power View, more ways to analyze data, smarter formulas and creating better looking charts.
What about you?
What are you planning to learn this year? Please share in comments.

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?

I want to key a range of dates, (7/1/09-7/12/09) then write a macro to go find the info for that range and bring it back to my spread sheet.
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...

talking about dates, therz a formula that i use very frequently to calculate the difference between two dates.
its not documented in 2007 though
=DATEDIF(START_DATE,END_DATE,"Y") - gives you the years
=DATEDIF(START_DATE,END_DATE,"YM") - remaining months
=DATEDIF(START_DATE,END_DATE,"MD") - remaining days
im sure you'll know this. wonder why it isnt documented. works fine with 2003 and 2007

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/
[...] Process your data: Assuming your data looks like what I shown to left, just use simple formulas to make it look like the table to right. [related: how to work with dates & times in excel] [...]

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
in time - 9:30 am on 11/24/2015

If I have dates in Indian format dd-mm-yyyy, excel is not recognizing the same and instead treating the same as mm-dd-yyyy so a date mentioned in Indian system as 09/06/2013 is being treated as 6-Sep-2013 whereas it actually represents 9-Jun-2013.

Chandoo,
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

@Jenny
It is poor practice to store multiple records in one cell
It is much easier to store multiple records ion multiple rows
That also allows flexibility in reporting
When entering data in a record that is mostly similar to the record above, you can use the Ctrl+D shortcut, This duplicates the cell directly above you speeding up data entry
Hello,
Could you please tell me the solution to this? I have spent months, years, looking for it...
When I press ctrl+; to enter the date in a cell, I want it to enter d/M/yy. My short date in windows regional settings is d/M/yy. Excel enters d/M/yyyy. 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?
Alternatively, how can I assign that key to my own shortcut for a macro to enter NOW with custom date format? Can't find that either!
I hope you can help!
Many thanks

I have to develop Calendar in Excel considering Monday being the First day of week . How I can develop the same ? Please provide me guidance .
Hi Chandoo!
I export incident data daily to Excel 2016 and the dates are text (e.g. 8 Apr 2018). I changed cell to short date field format, but it still recognises this as text until I 'F2' then 'Enter' in each cell. Is there a more efficient way to do this; I have 3 columns of dates and about 1000 lines of data.
I need it to be dates so I can then create pivot tables and charts from the data.
Many thanks,
Kirst.
Hi Kirst
You can use Data-Text To Column to change one column at a time.
You only need to change the Column Data Format - Date to DMY and click Finish.
Thank you very much!
some things I find useful:
INT this will give you the date part of a datetime field
MOD this will give you the time part of a datetime field
if you had
21/06/2018 10:25:00
in cell a1
then =INT(A1) would give you 21/06/2018
and = mod(a1,0) would give you 10:25:00
oSUM!
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.
Results in some infuriatingly subtle bugs when you forget!
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!
@Kale
Select the whole range
Then apply a Custom Number format (Ctrl+1)
want to conditional format and highlight all sunday and only second and fourth saturday in the list of given dates

Hi,
Option 1 is very much helpful for me.
I look this type of formula on google since many times but not satisfied.
Finally I found it.

Great website. These excel formulas, not just this page, have been super helpful while going through old spreadsheets and finding data. Thanks for the info.
Very informative. Date functions are very important. I frequently visit your articles...awesome. Go ahead.
Nice content, keep sharing with us.
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
