This Blog was initially called Excel 2007 with ExcelMaster. Time has passed now and we’ve got Excel 2010, Excel 2011 for the Mac and now Excel 2013

Anyway, this Blog contains an ever growing set of detailed pages on How to … do things and pages of simple but very useful Tips.

Books One, Two and Three of my series of three books, Excel Solutions for Accountants, are now online here:

Book One http://bookboon.com/en/excel-solutions-for-accountants-book-1-ebook

Book Two http://bookboon.com/en/excel-solutions-for-accountants-book-2-ebook

Book Three http://bookboon.com/en/excel-solutions-for-accountants-book-3-ebook

7th August 2015: I have given up on trying to get the Tips Others menu to work and by the time you are able to read this and act on it I should have put all of the missing files on the How to Other menu. I hae no ideea what goes wrong but I do everything as normal yet they don’t appear. I did it and checked: there are FOUR new pages at the top of the How to Other menu now … I won’t add anything else to the tips menu again unless I can get it to work properly.

This is my news this week: a delegate this week suggested that since he’d never heard of Sparklines they must be rubbish! I have prepared a page ilustrating a few of the things that Sparklines can do that are a bit different from what I hav written about before: a Sparkline Histogram for example!  It’s not on this blog though, it’s on my newly revamped web site at this address: http://www.duncanwil.co.uk/sparklines.html. In fact, it’s the first new technical page on the new version of the site. Apart from the home page, it’s the only page!! I won’t abandon this blog and I won’t put things on the site that aren’t here … I am not sure what the role of the site is yet but I’ve owned that domain since 2001 and I just renewed it for three years so it’s staying put!

29th July 2015: Where does time go? It’s a month since I was last here!! Shocker. Take a look at up arrow red? though. It’s a winner!! Tips menu, other, this time!

23rd June 2015: Wow! a month away. Time flies!! Here is a fascinating page, of sorts! Following the birth of my daughter I plotted all of the foetal data that I had and found that she developed perfectly normally. However, I found the percentiles generated by the scanning software in the doctor’s scanner might be suffering from badly programmed percetiles. Take a look. Excel How to menu, other!

10th May 2015: two files at once: Benford’s Law then Simulation of Coins and Loaded Dice. Really interesting Excel files on which these two summary pages are based. Both pages are in the How to menu and are well worth a read!

29th April 2015: Want to know how Apple makes its money? How does Apple make its money?I t’s not the be all and end all but this page will show you how to interpret regression analysis to identify things like that! Look for Apple Barrel in the Excel Tips … other menu.

19th April 2015: Numbers as Values… this can be a nightmare. I forget some things when I don’t use them very often. Today I forgot how to turn text to numbers … an old, old story. LEN() was my knight in shining armour. Mene: Excel tips … Other.

6th February 2015: two new cases that you can read about in the How to Menu … Other. Not earth shattering in terms of difficulty but one turns about 4100 cells of data into an interactive table of just 9 cells of information. The second case turns a photo of part of a newspaper article into an informative table and graph.

23rd January 2015: Find and Replace Menu with Data Validation: a video, a PDF file and an Excel file … with a job for you to do. You might be surprised at what is hiding in the Find and Replace menu in Excel: take a look.

That is the title of my new book on Excel and here is the Introduction to the three volume set: a total of about 200 pages.

Introduction to Excel Solutions for Accountants

Duncan Williamson

April 2015

This book will be published by www.bookboon.com early in June 2015 and of course this introduction is subject to change between now and then.

This is the first in a series of three books with the title of Excel Solutions for Accountants.

The essence of the book is that we have chosen a series of topics that we believe are of direct interest and relevance to accountants: we know that from the work we do every day. That is not to say that everything an accountant ever needs or does is included in this book; rather it’s a general book aimed at the accountant who knows that Excel can be made to do a lot more than it does but he just doesn’t know what that might be.

We have taken a very hands on approach with this book and for everything we talk about there is something for you to do: there is a spreadsheet for you to work with, too, so that you can always check your work and your accuracy at every stage.

One of our over riding ambitions was to make this book both as direct and as easy to use as possible. You will not find massive files with hideously complex formulas in them, each of which might take you an hour or two just to begin to unravel. What we have done is to give you straightforward examples with non complex lists and databases so that you come to learn the techniques and functions rather than worrying about the database.

Part One of the book comprises the following

  • Accountant Specific 1
  • Excel Tables
  • Depreciation
  • Ratio Analysis 1
  • Graphs 1
  • Pivot Tables 1

You can see immediately from the titles of these chapters that the accountant is the target here!

Secondly you should see that four of the chapters have the number 1 after them: that tells you that in books 2 and/or 3 there is another chapter or chapters on the same topic. Take a look at the contents of books 2 and 3:

Part Two Part Three
Accountant Specific 2 Accountant Specific 3
Compound Interest and Discounting: the time value of money Dashboarding
Data Validation and Form Controls Pivot Tables 3
Ratio Analysis 2 Forecasting
Graphs 2 Budgeting
Pivot Tables 2 AGGREGATE, OFFSET and SOLVER

More than one way to skin a cat! We present one or more solutions to the problems we present in this book and from time to time we say: Excel provides more than one way to solve this problem. If you already know a better way to solve a problem than we are presenting, stay with it. Even if you think our method is better but are happy with your own method, stick with it if it doesn’t mean you are wasting time or being inefficient. Don’t be stubborn though: like the cost accountant who saw our solution to his problem but preferred not to follow our advice: that meant he preferred to wait 20 minutes every morning for his main Excel file to open and then wait a further 45 seconds or so every time he pressed the Enter key. Our solution meant no waiting time at all as we replaced his 30,000 volatile function workbook with a Pivot Table based solution that provided almost instant responses.

Templates: we have tried at every stage of every chapter of this book to provide templates for you to work with and/or create. After all, what’s the point of programming a spreadsheet over and over again when you shouldn’t have to? Excel deals with some of the most predictable things you can do and templates are consistent with that. Therefore, take each of our examples either as a template or as your template in the making. We stress PPP too: paper, pencil, plan. The PPP approach means, don’t just dive in to a spreadsheet problem, take you time and plan it out on paper first. Then develop your solution. Then derive your template if appropriate.

A total of 18 chapters and by the end of all three books we believe you can easily call yourself an intermediate user of Excel. We also feel that you will have unlocked so much potential in Excel that you will want more and more from it.

This book has been written with Excel 2013 for Windows: that will mean that some of the things we have done will be a little bit different sometimes from what any other version of Excel might do. We have kept such differences to a minimum, however. Nevertheless, we would encourage you to upgrade to 2013 soon anyway.

Other sources of help for Excel: there are many sources of help other than Excel itself. Here are just a few examples of where to get help: just search for these online to get there!

  • excelmaster.co: my own Excel Blog
  • Excel-G: online/email based discussion list for general level questions on Excel. There are about 1,000 members of this group and they are friendly and really helpful people. Please note, this is a general level list and anything too advanced should be directed at …
  • Excel-L: online/email based discussion list for Excel Developers. This is the more advanced list and seems to concentrate mainly on VBA problems and solutions.
  • OzGrid: this is a free and commercial site offering some brilliant resources.
  • chandoo.org: this is another really useful site whose founder, Chandoo, has the objective of making you awesome in Excel! A lot of the materials on this site are free but some of them are commercial. Chandoo also offers online and offline courses.
  • Jon Peltier: Jon seems to be the world’s foremost authority on graphs and charts. Again, this is a combined free and commercial site but there are many wonderful free resources on there.
  • Mr Excel: Bill Jelen is a prolific Excel materials developer and explanator! Bill provides a lot of free and highly commendable materials, again both free and commercial.
  • Charley Kyd: Charley has specialised in the past in dashboarding and whilst he still does that, he offers a lot of free Excel based materials too. Well worth searching out.
  • John Walkenbach: John has been around for ages and he writes the Excel Bibles, among other Excel based titles. John is always comprehensive and has a lot of useful things to offer
  • YouTube: there are many thousands of videos on YouTube now and more appear every day. Some of them are really very good and others will leave you wondering what on earth they were trying to say. It’s pot luck really but once you find a good YouTube provider, stick with them!

There are many more people/organisations/lists that can help you so these are just a few of the ones we recommend.

Two New Cases

06 02 2015

Here are two new Excel based cases I have just prepared that I know some of you will appreciate.

UK Petrol Prices

I downloaded a file of all retail petrol and diesel prices for the UK from 2003 to 2014. The task is to prepare an interactive table so that the user just enters a date in one cell and the table then shows the

  • retail pump price per litre
  • duty per litre
  • VAT percentage
  • calculation of the cost of the petrol net of duty and VAT

This case involves the use of a variety of techniques including

  • VLOOKUP()
  • Data Validation
  • IFERROR()
  • Paste Special Multiply

Here’s an example of my output:

petrol_costs

 

This video summarises the case:

Sleep Requirements.

In today’s Borneo Bulletin newspaper there is an article on the sleep requirements of people of all ages. They give the requirements such as, a new born baby needs from 14 to 17 hours a day … someone over 65 years of age needs from 7 to 8 hours sleep a day.

The task is to turn a photo of the data into a table and a chart that communicates as effectively as possible: I prepared the following:

sleep_graph

sleep_table

 

Please feel free to write to me at any time to ask for the spreadsheets that accompany these cases. At the moment they are live cases and I won’t release them generally until the course has finished in a week’s time..
