Excel formulas can always be very handy, especially when you are stuck with data and need to get something done fast. But how well do you know the spreadsheet formulas?
Discover these 15 extremely powerful excel formulas and save a ton of time next time you open that spreadsheet.
1. Change the case of cell contents – to UPPER, lower, Proper
Boss wants a report of top 100 customers, thankfully you have the data, but the customer names are all in lower cases. Fret not, you can Proper Case cell contents with proper() formula.
Example: Use
proper("pointy haired dilbert")to get Pointy Haired Dilbert
Also try lower() and upper() as well to change excel cell value to lower and UPPER case
2. Clean up textual data with trim, remove trailing spaces
Often when you copy data from other sources, you are bound to get lots of empty spaces next to each cell value. You can clean up cell contents with trim() spreadsheet function.
Example: Use
trim(" copied data ")to get copied data
3. Extract characters from left, right or center of a given text
Need the first 5 letters of that SSN or area code from that phone number? You can command excel to do that with left() function.
Example: Use
left("Hi Beautiful!",2)to get Hi
Also try right(text, no. of chars) and mid(text, start, no. of chars) to get rightmost or middle characters. You can use right(filename,3) to get the extension of a file name 😉
4. Find second, third, fourth element in a list without sorting
We all know that you can use min(), max() to find the smallest and largest numbers in a list. But what if you needed the second smallest number or 3rd largest number in the list? You are right, there is a spreadsheet function to exactly that.
Example: Use
SMALL({10,9,12,14,26,13,4,6,8},3)to get 8
Also try large(list, n) to get the nth largest number in a list.
5. Find out current date, time with a snap
You have a list of customer orders and you want to findout which ones are due for shipping after today. The funny thing is you do this everyday. So instead of entering the date every single day you can use today()
Example: Use
today()to get 08/13/2008 or whatever is today’s date
Also try now() to get current time in date time format. Remember, you can always format these date and times to see them the way you like (for eg. Aug-13, August 13, 2008 instead of 08/13/2008)
6. Convert those lengthy nested if functions to one simple formula with Choose()
Planning to create a gradebook or something using excel, you are bound to write some if() functions, but do you know that you can use choose() when you have more than 2 outcomes for a given condition? As you all know, if(condition, fetch this, or this) returns “fetch this” if the condition is TRUE or “or this” if the condition is FALSE. Learn more about spreadsheet if functions like countif, sumif etc.
Where as choose(m, value1, value2, value3, value4 ...) can return any of the value1,2.., based on the parameter m.
Example: Use
CHOOSE(3,"when","in","doubt","just","choose")to get doubt
Remember, you can always write another formula for each of the n parameters of choose() so that based on input condition (in this case 3), another formula is evaluated.
7. Repetitively print a character in a cell n number of times
You have the ZIP codes of all your customers in a list and planning to upload it to an address label generation tool. The sad part is for some reason, excel thinks zip codes are numbers, so it removed all the trailing zeros on the leftside of the zip code, thus making the 01001 as 1001. Worry not, you can use rept() the extra needed zeros. You can also custom format cell contents to display zip codes, phone numbers, ssn etc.
Example: Use
zipcode & REPT("0",5-LEN(zipcode))to convert zipcode 1001 to 01001
You can use REPT("|",n) to generate micro bar charts in your sheet. Learn more about incell charting.
8. Find out the data type of cell contents
This can be handy when you are working off the data that someone else has created. For example you may want to capitalize if the contents are text, make it 5 characters if its a number and leave it as it is otherwise for certain cell value. Type() does just that, it tells what type of data a cell is containing.
Example: Use
TYPE("Chandoo")to get 2
See the various type return values in the diagram shown right.
9. Round a number to nearest even, odd number
When you are working with data that has fractions / decimals, often you may need to find the nearest integer, even or odd number to the given decimal number. Thankfully excel has the right function for this.
Example: Use
ODD(63.4)to get 65
Also try even() to nearest even number and int() to round given fraction to integer just below it.
Example: Use
EVEN(62.4)to get 64
UseINT(62.99)to get 62
If you need to round off a given fraction to nearest integer you can use round(62.65,0) to get 63.
10. Generate random number between any 2 given numbers
When you need a random number between any two numbers, try randbetween(), it is very useful in cases where you may need random numbers to simulate some behavior in your spreadsheets.
Example: Use
RANDBETWEEN(10,100)may return 47 if you keep trying 😉
11. Convert pounds to KGs, meters to yards and tsps to table spoons
You need not ask Google if you need to convert 156 lbs to kilograms or find out how much 12 tea spoons of olive oil actually means. The hidden convert() function is really versatile and can convert many things to so many other things, except one currency to another, of course.
Example: Use
CONVERT(150,"lbm","kg")to convert 150 lbs to 68.03 kgs.
UseCONVERT(12,"tsp","oz")to findout that 12 tsps is actually 2 ounces.
12. Instantly calculate loan installments using spreadsheet formula
You have your eyes on that beautiful car or beach property, but before visiting the seller / banker to findout of the monthly payment details, you would like to see how much your monthly / biweekly loan payments would be. Thankfully excel has the right formula to divide an amount to equal payment installments over given time period, the pmt() function.
If your loan amount is $125,000,
APR (interest rate per year) is 6%,
loan tenure is 5 years and
payments are made every month, then,Use
PMT(6%/12,5*12,-125000)which tells us that monthly payment is $ 2,416 if you keep trying 😉
Also, if you want to find out how much of each payment is going for principle and how much for the interest component, try using ppmt() and ipmt() functions. As you can guess, even though EMIs or loan installments remain constant, the amount contributed to principle and interest vary each month.
13. What is this week’s number in the current year ?
Often you may need to find out if the current week is 25th week of this year. This is not so difficult to find as it may seem. Again, excel has the right function to do just that.
Example: Use
WEEKNUM(TODAY())will get 33
14. Find out what is the date after 30 working days from today ?
Finding out a future date after 30 days from today is easy, just change the month. But what if you need to know the date thirty working days from now. Don’t use your fingers to do that counting, save them for typing a comment here and use the workday() excel funtion instead. 🙂
Example: Use
WORKDAY(TODAY(),30)tells that Sep 24, 2008 is 30 working days away from today.
If you want to find out number of working days between 2 dates you can use networkdays() function, find out this and a 14 other fun things you can do with excel.
15. With so many functions, how to handle errors
Once you get to the powerful domain of excel functions to simplify your work, you are bound to have incorrect data, missing cells etc. that can make your formulas go kaput. If only there is a way to find out when a formula throws up error, you can handle it. Well, you know what, there is a way to find out if a cell has an error or a proper value. iserror() MS Excel function tells you when a cell has error.
Example: Use
ISERROR(43/0)returns TRUE since 43 divided by zero throws divide by zero error.
Also try ISNA() to findout if a cell has NA error (Not applicable).
Give these functions a try, simplify your work and enjoy 🙂

If I could have the same quality of graphics and illustration in Office Apps, I would certainly use it.

Chandoo,
First, let me say I love your blog. I like this post, and I think that technically (in terms of readability of data) your argument is correct. The bar of bars, and the table, are much better for readability and accuracy, and as you say would be much easier to produce.
But these points ignore the context of the chart. If the chart was part of a scientific paper, your solution would be a valid one. The context in this case is an illustrated atlas of wildlife. A companion graphic to go with written text. The importance of aesthetic goes up over readability and accuracy. Much of the data and points (I assume) will be covered in the text.
There's always a pure technical tufte-esque argument. But I sometimes think it ignores the value of aesthetics. (Which I admit are quite subjective)
Great post though. Thanks.
The Treemap makes the scope of the data much clearer! The 3D pie chart depiction is deceptive.
This reminds me of the videos ive seen on the internet where it compares the relative sizes of the earth with the larger planets, then the sun, then other stars in the galaxy. Eventually there is an image showing the largest star in the sky with a little pixel representing the sun.
My point is if you varied the size of the charts it would help convey the message. The first chart (salt vs fresh) would be the biggest and the rest would be arranged in descending order. I feel this would be more accurate.
It may be helpful to consider the advice of Steven Few and Edward Tufte regarding pie charts in general. To summarize, they are seldom the most useful way to present data. Here's Few's thoughtful piece on the subject.

Try putting the percentages on the bar charts instead of actual amounts. Lakewater would be .013 % instead of 52.
That is very good pie chart example.
Please send example file if it is possible.
It will work , even though colors may be confusing , it can be labeled well . Also it can be called as the drilled chart , as it drills in information further , like the first chart may show business in a region , second may drill into a particular region , thrid may further drill into wat products are there in that region . It works well for me , i would more vote for the 2 nd option .
Overall all this site is awesome ,
p.s : just like me
The risk with pie of a pie of a pie chart is that Jon may have a seizure by looking at it. Also, it isn't easy to read. 😉
I dunno. The only thing worse than a pie chart is a cascading series of pie charts. I don't even think they really lend themselves to this sort of thing. It just becomes a big hide-the-ball game with your viewer.
Those goofy connectors between the pies are pure chart junk. I can't really tell if the second chart has 2 series or 3 - because the connector is a different color than the 2 labeled slices. Despite that, even whereas the drill down kind of works, still the individual components suffer from the same old weaknesses that 3d pie charts have.
Use a large bar chart as your "cover story", and fill in the sub points with smaller bar charts - or even go grab the Fabrice SFE project for extra butter. Use page orientation, color, and some text styles to guide your audience through the drill downs.
FWIW, if you check out the guy's site, you can find several other truly mortifying charts:
http://www.andrewdavies.com.au/index.html
The methane emissions one is particularly heinous. Although, I'm kind of debating what I think about the 'Glacier Changes" chart. I'd kind of like to see the data on that to see how it would look in a more traditional horizon chart.
Thank you, that was scary. I don't understand the "Glacier changes" Chart at all...
Its a very nice way to represent the data, especially when we have sets and sub-sets within the data.
I like these!
Except for the fact that they aren't dynamic and hence must be setup manually each time
It would also be nice if they could be interrogated as in select a different segment and the new data falls out automagically, but then none of the standard Excel charts do that either.
I'd like it better if the bars were stacked. How about this idea (I hope I can convey it in words):
First bar is vertical and stacked.
Second bar is horizontal, stacked horizontally and the same proportion had it been on the first bar.
Third bar is vertical, stacked vertically and the same proportion had it been on the second bar.
Then it would really look like you are zooming on the chart, like the Powers of Ten video, or maybe like the golden ration spiral.
These looks shunting but setting up for each step makes kicks them out. However if these can be arranged automatically by native excel or by VBA, these will be the part of my "Archery"
I agree with Chandoo's Suggestion about the Bar Graph which represents data in a very appropriate manner. Even I prefer doing the same. I seldom use Pie Chart unless required.
That's a real nice example of a missleading infographic. But to be honest, I think chandoos suggestion is not much better!
Why are pie charts bad? I think because they don't show the real size-relations. The biggest pie in that example ist 300k big. The 2nd one has only the size of 10k, about 3% of the first one. Niether the pies nor the bars show the real sizes. I jnow, it's hard to show the sizes because the values of the second and the third pie are so small. But that's what visualization are about - showing relations to allow the reader to see the real sizes!
So how to show the real figures?
First possibility is o use a 1:1 scaling. Well then, you need a very big screen to show also after a 90° rotation, wihich I would prefer because it's a structural comparison and not a timeline. Maybe that solution is not the perfect way.
The other chance you have is to zoom in but to really show that you zoom in! http://www.pro-chart.de/images/Water_Fall.png maybe gives you a first impression what i mean. (i was a quick try, done in 10 minutes)
The next way is, maybe to fold the bars like in the financial report 2011 of the Post of Switzerland page 22. That chart is based on an excel chart. Maybe can explain you how to do it 😉
Financial Statement: http://www.post.ch/en/post-startseite/post-berichterstattung/post-berichterstattung-service/post-berichterstattung-downloads/post-gb-2011-finanzbericht.pdf
page 22: http://www.pro-chart.de/images/FS_Schweizer_Post.png
A way that is not so very common is to divide the bars in a lot of single datapoints. So maybe the 390k bar then consists of about 5,000 single datapoint. That's not possible - it is! Have a look:
http://www.pro-chart.de/images/Dotted_WF.png
It's pure excel!
Now one single point ist 0,2% of the whole (in the example above). Add more datapoints and you can visulize the very big and the very small numbers!
Wish you a lot of fun - visualizing with excel can be very powerful!

Hey Joerg,
I don't dig so much the dotted waterfall thing. But this is kind of awesome:
http://www.pro-chart.de/images/FS_Schweizer_Post.png

Normally I don't learn post on blogs, however I would like to
say that this write-up very compelled me to try and do so!
Your writing style has been amazed me. Thank you,
quite great article.
This is very impressive, I would like to learn how to build this for myself. I have tried for some time now, is there a step by step process on how to create these waterfall pie of pie charts?
I am novice to excel and use it very seldom. But your blog contains to the point information one needs to get going.
I was searching for a trick to do a Pie chart drill down - for example the first pie chart shows how the prices are distributed between perishable and non-perishable items.
Now if we want to know how the perishable items are distributed - one can click the segment and it will draw another pie chart with distribution of all different perishable items (milk,meat,fruit,veg etc)
So do you have any such trick?

electrojit
I like the look of your pie of pie of pie chart, although I understand that the relative size of each pie does not represent the actual percentages.
