Extract Numerical Data Points from an Image - Today Gartner released the 2019 magic quadrant for Business Intelligence.  As expected (by me at least), Microsoft is continuing its trail blazing and now has a clear lead over Tableau in both ability to execute and completeness of vision.  I thought it would be interesting to see a trend over time for the last 5 […]

Neville:  Keeping track of Power BI Desktop’s amazing features since it went GA is difficult, […]
calendar overrun in Power BI
Calendar Over Run While Comparing Last Year’s Data - Recently, I was helping someone on Power BI community forum on the issue of calendar over run while comparing values with last year’s data. I thought it would make a good article to share with others. The Problem I will illustrate the issue using the AdventureWorks database (I need to make some tweaks to do this).  […]
Copy measures between PBIX files
Copy Measures Between 2 Power BI Files - I have often been asked (and wondered myself) if it were possible to move all the measures from one Power BI PBIX file into another.  Imagine you have 2 PBIX files with similar data models (similar enough that the measures will be substantially the same).  It doesn’t matter how you got to this point – […]
Import First Sheet with Power Query
Import the First Sheet in a Workbook with Power Query - My series about common patterns for loading data using Power Query received quite a lot of interest over the last few weeks.  You can review those articles in the links below Combine all files in a folder with Power Query. Load the Latest Version of a File with Power Query. Combine all sheets in a […]
A further (final?) update about Power Pivot - This is the longest running blog post series I have on my website.  Why does Power Pivot Crash so often and what can I do about it?  I have three previous articles that you can read in the links below Original post (Oct 16): Does the Power Pivot Excel Add In Crash for You? Follow […]
Combine All Sheets in a Workbook with Power Query - There are quite a few different common business scenarios where you get data in the form of a file on a regular basis.  The 3 common patterns I use most often are. Each day/month/year you get a new file containing incremental data.  All the data in all the files need to be combined and loaded. […]
Best Book for Learning the M Language - Late in 2018 there was a new Power Query book written by Gil Raviv called Collect, Combine and Transform Data Using Power Query in Excel and Power BI.  That’s a bit of a mouthful actually; maybe the title was influenced by the same people that call Power Query “Get and Transform” in the Excel menu?!   […]
Load latest file in Power BI
Load the Latest Version of a File with Power Query - There are quite a few common business scenarios where you get data in the form of a file on a regular basis from some source system and you need to process these files into your Power BI reports.  There are 3 common patterns that come to mind. Each day/month/year you get a new file containing […]
Power BI Desktop Release Date History – Using Power BI - I was chatting to a few of my Power BI buddies during the week about when we thought the December 2018 update would be released.  It seemed to me that under normal circumstances the new version is released on or about the first Monday (US time) on or after the 3rd or 4th day of […]
Rename Blank in a Slicer in Power BI - A common problem I see some people struggle with in Power BI is when a slicer contains a (Blank) record for some reason.  The cause of the problem is not obvious and hence it is not clear how to fix it.   This article describes what causes this to occur and also how to fix it […]
Importing XLSB into Power BI - I had a question from one of my online Power BI Training students just this week who was struggling to import data from a large *.xlsb Excel file.  I suggested she save the file as an XLSX file and try again – and that worked a treat.  But the question is why?  I had an […]
Moving Queries from Power BI Desktop to Dataflows - A few weeks ago I wrote an article introducing dataflows in Power BI and discussed why you should care about them.  There are a few questions that have been spinning around in my head since then, significantly: What implication is there to the Power BI Golden Dataset as a result of the new dataflows? Should I […]
Create a Planning View of Your Outlook Diary in Power BI - I was chatting to my wife the other day discussing all the things we want to do next year. It has long been a pain in the butt to get a high level (big picture) view of your Outlook diary to see what is happening (think forest, not trees).  In the past I have used […]
Power BI Dataflows, and Why You Should Care - Microsoft recently released a new feature in Power BI called “Dataflows”.  You may have seen it pop up in a recent release of Power BI Desktop under Home\Get Data\Power BI Dataflows (beta) as shown below. It is also visible when you log into and go to an App Workspace as shown in 1 below.  […]
Power BI Training
Power BI is an Enigma, so What to Do? - Power BI is an enigma.  On the surface Power BI is an alluring product that promises to change your world of data analytics for the better – and indeed it can and will.  But sitting just beneath the surface, hidden from view, is the reality that there are many things you must learn if you […]
When to Use SUM() vs SUMX() - Level: Beginners/Intermediate (Updated Oct 2018). This is a further (third) update/edit to an article I first wrote 3 years back and then updated a year back.  When I update my articles I simply change the original post with the latest data – that way only the current/latest version is available preventing people stumbling on old […]
Create a Power BI Slicer Panel - There is nothing worse than having a Power BI report that has 50% of the space taken up with slicers.  When this happens, you only get half the page to visualise the actual data.  But on the flip side, if you don’t have the slicers it can be harder for the report users to filter […]
Data Profiling in Power BI - Today Microsoft released the October 2018 update of Power BI Desktop.  One of the fabulous new features that has been released is the ability to get a visual profile of your data in Power Query BEFORE you load the data.  This new feature is typical of the type of development effort Microsoft is investing in […]
Visually Appealing Power BI Reports - One thing I often get asked is “How do I create good looking Power BI Reports?”.  This is a very good question and unfortunately the answer is not straight forward.  I like to think of the visual appeal as the “Art” of communicating data insights.  The other major consideration is “what and how” to communicate […]
