ARE YOU INTERESTED? A while ago I prepared a very comprehensive bookkeeping case study: mainly concerned with the bookkeeping cycle, loads of debits and credits, trial balance, adjustments, final accounts. I programmed a spreadsheet to cope with a two year cycle for an imaginary business. There are also very comprehensive notes to go with it. If you would like a copy of notes and spreadsheet, let me know … send me an email. This case is aimed at teachers of bookkeeping and accounting as well as students and is really level two work, not introductory.
27th April 2014: I joined a discussion on LinkedIn, Financial Modelling Group where there was a question about the Payback Period method for Capital Investment Appraisal.

17th July 2013: back from my latest trip and I come bearing gifts … two mini projects and a nice little formula to learn. By the way, my first mini project was another one concerning a VERY slow spreadsheet. I watched in horror as this work book took at least 20 minutes to open. I was allowed to root round the file and very quickly ended up in a cell far far away from A1. In summary I was able to delete around 22,000,000 cells that each contained a formula that was being updated when Excel recalculated and opened. These formulas were created accidentally when the user clicked to fill down and for some reason it filled all the way down to row 1048576 instead of stopping at row 64800 where it should have stopped. The file opened normally after that! Go to the How to Others in the menu to see this new page: Mexican Projects!
Just follow the menus above and you will find a richness of content.
Here are the links to my three new books.

Bora wrote to me last week and asked for my Excellent help. I responded by saying, ok, I can do this on Monday. She replied to say, Wow! I didn’t expect you to reply!!
It was an interesting problem: a database with over 41000 rows needs to be interrogated using four variables. I offered two separate solutions: use and sort on an Excel Table and use SUMIFS()
Both solutions worked a treat and Bora was delighted I am happy to say.

I have seen snakes around the house, on the road, in the bushes. Yesterday I saw TWO snakes around the house. One small, grey/brown, slithered under the gardening things at the back of the house and I left it alone.
A much larger, grey speckled snake, was meandering around the house and I couldn’t ignore that one. I have tried to identify both snakes but without success so far. With this one, whilst appreciating that it eats mice and rats and so forth, I took the view that it could be poisonous and a threat to the family. I dealt with it.

Another course completed and another post for the blog just suggests itself naturally.
This week a delegate wanted to know how to find the weighted average cost of capital for his company: not just an academic view but a real WACC value. One of the aspects of WACC that is often a bit tricky is to find the value of Beta. It’s easy to find Beta values for listed companies in the UK, Europe and the USA but this company is in Saudi Arabia and I could not find the Beta value on the Saudi stock exchange web site.
What I did was to go and find a sample of the changes in the index of the entire stick exchange and the changes in the price of the share. I found the information I needed at bloomberg.com and here is the table I prepared in the Excel file:
All we need to do then is to create this formula: =SLOPE(C5:C12,B5:B12) … in cell E16 and the estimate of Beta this gives is 0.8314 … with a market Beta of 1, this tells us that Savola is rather a conservative company as far as the Saudi stock market is concerned.
If I have time over the next week I will try to expand this table to 70 prices and changes to give us a more reliable estimate of Savola’s Beta.
Watch this space!

I had a delegate this week whose Pivot Tables would take any of his numerical data and by default count them rather than sum them. When he asked me why that happened I went through the normal explanation of data v numbers … which is true. However, in his case there seemed to be no reason behind this phenomenon: his data was clean as he was using my files and no one else had the same problem. He was using a good quality company laptop too.
We both checked on the internet last night and gained nothing from the many discussions on this problem: most of which related to data v numbers I have to say.
This morning I suggested that we look at his Windows Regional etc settings. His default language etc was US English and that seemed to be in order; but I said, let’s try this, change it to UK English and see what happens.
Ta daa! For some reason, this change did the trick and now this delegate’s Pivot Tables sum his data rather than counting it.
Another success story fromExcelMaster!

UPDATE: 16th January 2014: I have been using this technique since I last reported and I have found some limitations AND solutions to this reverse pivot technique. I will prepare a page and video to demonstrate what I have found.
2nd December 2013
Watch the video and then imagine that you have downloaded a five year set of financial statements for a company. Nothing wrong with the data or the database they came from but imagine you want to set up a pivot table from them. Probably not possible unless you are lucky enough to have a data provider who has designed their output with this in mind.
Let’s cut a long story short: open this file amazon_case_reverse_pivot and try to apply the reverse pivot technique in my video to the data you will see there. Good luck and it will be worth any effort you put into it! PLEASE READ THE NOTES in this work book re copyright …
I didn’t invent this technique but I learned it a couple of weeks ago and used it in earnest just now … watch the video!
I had a table that had months across the top, years down the left hand side and data in between. What I wanted was the data in a list in three columns:
year month value
transposing, rotating, copying and pasting can give you what you want but it will take a long time. My original table covered all twelve months and five years …
Reversing a Pivot table is what it’s called and this is how to do it:
- Press Alt + D then P to call up the pivot table wizard and select Create a “Multiple Consolidation Ranges PivotTable.”
- Select “I will create my own page fields”.
- Select your data range and choose 0 page fields
- When you see your pivot table, double click on the intersection of Row Grand and Column Grand, in the bottom right hand corner of your pivot table
- You will be presented with your new table in the form of a list … that is, from pivot table style to list style … it’s magic!

I know I learned this function a while ago but then I forgot about it. The aggregate function was newly created for Excel 2010 and it provides us with some interesting functionality: overcoming shortfalls in the performance of such functions as AVERAGE, MIN, MAX, LARGE, SMALL and a few more … 19 of them altogether. The trouble is, good as it is, it is not that simple to apply. What I have done then is to create templates that will help you to use the aggregate function in one or both of the formats in which it might be used.
From the Excel Help File:
Returns an aggregate in a list or database. The AGGREGATE function can apply different aggregate functions to a list or database with the option to ignore hidden rows and error values.
AGGREGATE(function_num, options, ref1, [ref2], …)
AGGREGATE(function_num, options, array, [k])
The AGGREGATE function syntax has the following arguments (argument:
Required. A number from 1 to 19 that specifies which function to use
Required. A numerical value that determines which values to ignore in the evaluation range for the function
Required. The first numeric argument for functions that take multiple numeric arguments for which you want the aggregate value
Optional. Numeric arguments 2 to 253 for which you want the aggregate value
For functions that take an array, ref1 is an array, an array formula, or a reference to a range of cells for which you want the aggregate value. Ref2 is a second argument that is required for certain functions. The following functions require a ref2 argument:
The AGGREGATE function is designed for columns of data, or vertical ranges. It is not designed for rows of data, or horizontal ranges. For example, when you subtotal a horizontal range using option 1, such as AGGREGATE(1, 1, ref1), hiding a column does not affect the aggregate sum value. But, hiding a row in vertical range does affect the aggregate.
My templates will tell you if you are trying to use the wrong format of aggregate and has then been set up to ensure you don’t make any other mistakes when using it. This includes providing combobox guidance for choosing which functions and options you need to use.
The Excel file is available here: aggregate_function … just click!
