This is a guest post by Sohail Anwar.
Why do so many of us use Excel? Let’s trace it back to the ’80s when Microsoft hit gold by being the first out of the blocks with the widely available operating system that was somewhat dummy proof.
Suddenly everyone could aspire to launch ‘Nukes’ like a fresh faced Matthew Broderick in the film ‘War Games’. 
By the early 90’s Windows had become even more established relative to other Operating Systems, so much so that PC manufacturers were developing components around Windows’ capabilities and suddenly PCs were Windows machines. As big business began accepting the significance of computing, Microsoft started winning huge licensing contracts with all the major corporations in all sectors, but the Finance sector in particular, where Excel would be king, was having an exponential boom at this time. For big organisations, once you spent a fortune buying licences for the Operating System it only made sense to purchase the seamlessly integrated and carefully developed/tested apps to run on them; enter Excel, Word, PowerPoint and eventually Outlook. Fast forward to 2015 and we are firmly in the age of second generation corporate professionals who have developed much of their productivity skill sets around those particular Windows tools. While all the excellent tools have their place, Excel stands out and here are 8 reasons why you need to up your Excel game more than ever this year.
1. Excel is a universal language spoken in almost all offices
For those who work in the field of Finance, it’s more common to hear ‘Excel’ than it is to hear ‘Spreadsheet’. Such is the ubiquity of Microsoft’s brilliant application. Of course the purists will tell you 279 reasons Excel is not as good as ‘insert competitor product’ but the reality is 1) Purists aren’t coming from a pragmatic perspective which modern multi-skilled professionals need to be and 2) as mentioned in the intro, like it or lump it, Excel is everywhere!
2. Stop thinking of Excel as a spreadsheet
It is a problem solving tool. I’m not saying it’s not a spreadsheet, accountants and financial analysts will often use it as a traditional spreadsheet but this is just a fraction of what it is capable of. So many other professionals will not correctly harness the awesome power of Excel because they believe it to be nothing but a boring spreadsheet application that deals with boring numbers. Case in point, three of the most common uses of Excel in my work include dealing with Text data, i.e. Lists of people from HR databases that need to be reconciled with other sources, sending out large volumes of tailored emails and creating PowerPoint presentations automatically! Those aren’t the things most people associate a spreadsheet with.
3. Create more time
The most precious commodity on Earth which cannot be replenished is your time. The better you become at leveraging Excel, the more you will be able to achieve. First the speed at which you are able to solve problems will increase and eventually if you get good with VBA then full on automation will save you hours per task. You cannot put a price on the time you will save; it will free up your own time to provide more value in your team, develop yourself in other ways (more skills or attributes), free up time to work on a side business/ hunt for a better, higher paying job or of course you can spend more time trying to break your candy crush high score!
4. Excel is not going anywhere
Excel will be around for a very long time. Big companies cannot easily migrate from established platforms and applications. Case in point, two of the banks I have worked for in the last few years still insist on the archaic 90’s Lotus Notes as their main communication tool! It’s not just the cost of doing so but in the case of Excel in mid to large organisations, Excel is a part of working culture. Even if companies would move, there is no all-encompassing rival, developed and supported by a reputable enough organisation on the horizon, compatible with all the bespoke .NET application development that goes on within organisations (which is designed to integrate with Excel). As a note, the trillion dollar business of Foreign Exchange currency trading as well as most other forms of trading still have most of their analysis work carried out in Excel in almost all financial institutions.
5. Small Data
Big data is so 2014, 2015 is about the rise of small data or local data; it has grown considerably in the last few years as companies have been spending more and more money on CRMs, ERPs, essentially databases. You need to be able to gather data, analyse it, draw some conclusions and present those conclusions as intelligence to decision makers. Don’t get left behind. I have worked with Project Management software like Clarity and most frequently SharePoint (content management)., With the likes of Clarity and other data repositories, you can extract information in formats that Excel likes (.xlsx, .txt & .csv) and then go about getting useful insights and creating reports.
6. Excel is like an analytical sketchpad
Excel is to an analytical professional what paper/pen is to an architect. I have pitched many ideas and models to my bosses by translating my wacky concepts in my head and interpreting those ideas in Excel, especially around finance, budgets and general reporting.
7. Value networking
This is my term for what in my career has turned out to be the best form of networking, not arbitrarily pestering people for coffee meetups but using that time to reach out to someone and make their life a little bit easier. Due to its universal nature, Excel has allowed me to proverbially raise my hand and say ‘I can help with that’. And I did help, helping peers alerted senior colleagues to my abilities and when the senior/Execs started reaching out me for my help, it opened up a whole new set of doors for me which meant good things for my career.
8. More Excel skills make you more marketable
Excel does not represent one skill on your CV, it represents a huge category of skills. In the age of keyword search hiring, you need to understand that simply writing ‘Excel’ or ‘Advanced Excel‘ will seriously undersell you to prospective employers. Use actual Excel functions in your Resume!
Pivot Table, VLOOKUP, Macros, VBA, Conditional Formatting, Charting and filtering…These are far more telling of your ability to an employer then writing Excel. Someone who writes VLOOKUP, Pivot Table, Filtering demonstrates an ability to analyse data and so has eliminated a potential barrier in the mind of the hiring manager reviewing the CV. Simply writing ‘Excel’ on your CV shows you can work with Excel, writing Pivot Table shows you can work with Excel and make it analyse data for you. Excel skills progression correlates well with earnings; the more you improve your Excel skills in a meaningful way to add value in an organisation, the more your earning power goes up.
To give you an example from my own career and many of the colleagues I have worked with and helped over the years: fairly intermediate skills took my earnings from £27k to £40k, getting very good with data analysis took me to £64k, intermediate level VBA took me to the £100k mark, becoming exceptionally good with VBA helped me climb eventually to £140k+. Bear in mind, blindly learning Excel is not something I advise, instead the method for improving is to find opportunities in your work to be more productive. In parallel to improving my Excel skills, I was developing other key attributes too such as Project Management, Reporting expertise and communication. It was exposure to problems in those areas that gave me reasons and opportunity to apply my Excels skills and solve very specific and niche problems which helped me stand out from the crowd more. People think you need to be a VBA god to break the 6 figure mark. When I did it, I was okay but spent a lot of time Googling and making lots of mistakes. When I helped a friend of mine do it she was at best able to manipulate other people’s code, her brilliance was in understanding where appropriate to apply solutions, speeding up and automating is what an employer values, not how pretty your code is.
Conclusion
Is Excel perfect? Maybe not for all scenarios but it’s damn good and for professionals, especially those working in or with mid to large sized organisations and who are (always should be) looking for career development, improving your Excel can go a long way to improving your overall offering as a professional.

Thank you Sohail for echoing my views. I was skeptical to publish this post as it mimics the theme for our podcast session 27 – 15 ways to get awesome in Excel in 2015. But there is no such thing as enough awesomeness. As a community, we are thirsty for more good stuff, all the time. Plus when was the last time you heard both Klingon and Excel in same sentence.
Please share your views about this (not Klingon you silly, about learning Excel) in comments.

If I could have the same quality of graphics and illustration in Office Apps, I would certainly use it.
If I could have the same quality of graphics in Office Apps (Excel, PPT) 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.
http://www.perceptualedge.com/articles/08-21-07.pdf
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?

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.
