Edit: Feb 2017. Microsoft has released an update that solves the problem described in this article. This article still has learning value however you should also take a look at the announcement from Microsoft here https://blogs.office.com/2017/02/08/january-2017-updates-for-get-transform-in-excel-2016-and-the-power-query-add-in/ There are many ways to combine data from multiple files into a single file/table in […]
This is the second of a series of articles where I explain different methods of combining data from multiple files into a single workbook/table. In the first article I described how to use a function to combine data from identical Excel Workbooks into a single file using Power Query. Next […]
I have blogged about these concepts before but thought there was value in creating a couple of clear blog posts covering step by step instructions on 2 good ways to combine multiple Excel Workbooks with Power Query. Both of these approaches require that the Excel files are identical in structure […]
I had an interesting problem this week with a client that uses a 445 calendar. The problem is that they had some monthly budget figures that they wanted to track against actual sales on a weekly basis. We agreed to do a straight line split of the budget into weeks […]
Power Pivot and Power Query are the best things to happen to Excel since the invention of Excel itself. Once you start using these tools there is no turning back. But someone asked me the other day “Is it possible to use Power Query with a traditional pivot table?” (ie […]
Level: Beginners I was helping a user at http://powerpivotforum.com.au with a question about collections reporting and thought it would make a good blog post. There are a few interesting concepts involved which I will explain as I go along. The scenario is as follows. We have 2 tables – one […]
Level: Beginners I have had some really good positive feedback from a couple of early readers of my new book “Learn to Write DAX”. “I purchased your eBook last Saturday and I want to let you know that I have learned more in the last 96 hours than I have […]
Level: Beginners No software company can build every single feature that everyone wants to see all at once. Ultimately there has to be some prioritisation, and along with the prioritisation comes compromises and ultimately disappointments for some (many?). Back in July 2015, Microsoft started a chain of actions and announcements […]
Before showing you how to do cross join in power query, let me tell you a story. I had a situation this week where I need to create a budget table in Power Pivot. I had a choice of either loading a weekly budget as a single record per store […]
The long awaited book from Ken Puls and Miguel Escobar has just been released in digital edition. I read this book over the weekend and wanted to share my experience with anyone considering buying this book or wanting to learn more about Power Query. This book is 220+ pages of […]
Level: Beginners Recently I was working for a client that required the matching of a list of data sent from a customer against some internal business data. This type of data matching is actually an audit process that I would have historically done with MS Access, but it occurred to me […]
Level: Beginners When you write a Power Query workbook in Excel 2013, you are given 4 choices of what to do with results. One of the choices is to load the resulting query directly to the Power Pivot data model. This choice does not exist in Excel 2010. It is […]
As regular readers of my blog would know, I attended the PASS Business Analyst Conference in Santa Clara California this year (April 2015). Here is the link for next year if you are interested. While I was there, I had the pleasure of presenting on one of my favourite topics […]
I was helping a participant at http://powerpivotforum.com.au with a problem. Long story short, she needed to return a table to Excel from a data model – not a Pivot Table. This concept can be a bit strange at first – let me explain. Tables – Not Pivot Tables A Pivot […]
Level: Beginners I helped a couple of people this week on the topic of creating multiple relationships between two tables. There is not a lot of information on this topic on the web so I thought I would write about it here. Power Pivot is not the Same a Relational […]
I am really looking forward with anticipation and excitement about the future of http://PowerBI.com. Microsoft has just released the August 2015 update to Power BI Desktop just 1 month after PowerBI.com becoming generally available (GA). Power BI Desktop used to be called Power BI Designer, and it is the tool […]

Level: Beginners One of the topics in my book “Supercharge Power BI: Power BI is Better When you Learn to Write DAX” talks about the optimal shape of your data tables. It is such an important topic that I have decided to share some modified extracts from the book here. When […]
Level: Beginners I have been working with a client here in Sydney were we are producing some Human Resource (HR) reporting tools to analyse what is happening across the business. HR data is quite often very sensitive because it can contain personal information as well as salary information. A lot […]
Level: Beginners I was working with a client recently and was asked a question… “How do I remove duplicate connections in Power Pivot”? I know this is an issue and I specifically advise people to be careful in my training courses and also in my book. But of course once […]
