Its always great to receive e-mails like this. Power Query is a game changer.
Power Query and Open Excel Files
Old school solution
Power Query can easily combine data from multiple Excel files. A problem can arise if one or more of the files is open. Power Query will generate an error and the import will fail. The solution involves an old school Excel feature.
Creating a table of all combinations in Excel [Video]
Power Query solution
Let’s assume you have three state codes and four department codes and you want to create a table of all the possible 12 combinations (3 x 4). How do you do it so that it is flexible? i.e. if you add a new state or department it must be easy to update the combination table.
Filter in Power BI Data View
Filtering coming soon to the Data view in Power BI. Fingers crossed this gets done soon – patience everyone.
Dates are Easy with Power Query
Getting the date right and save time
You can create complex functions with Excel to handle dates. But it makes more sense to get your data structured correctly and then you can use simpler date formulas. Power Query allows you to fix your data so that you can use those simpler formulas.
Power Query Privacy Setting Problem
Excel 2016 solution
Privacy settings allow you to control who sees the Power Query data. There seems to be a bug that remembers your response to a dialog and this ignores any changes to the Privacy settings. Find out the VBA line of code that can fix it.
PDF and Power BI
Looks like Power BI will soon be able to extract data from tables in PDF documents.
Great to see requests being acted on.
Understanding Filter Context in DAX

Are you trying to get your head around Filter context in DAX? I watched a video from the sqlbi.com guys and it explained it well. I thought I could add an Excel flavour to it.
Creating a Unique Dynamic List in Excel
A Power Query technique
There are a couple of techniques to automate a unique list of items in Excel. I have covered them in previous blog posts (see links below). I thought I would describe how to use Power Query to create a dynamic unique list.

If you are into statistics then you probably already know about the R language – but if you don’t it may be worth looking at.
It is open source code that is built to handle statistics and big data. It has some limitations when used with Power BI but it can be used on its own.
This article looks at using visuals created with R in Power BI.
DAX is the function and query language of PowerPivot and PowerBI. It has been around for a while, but it didn’t really have many editing tools until DAX Studio came around.
DAX Studio has been created by the SQLBI.com guys – the legends in PowerBI.
I saw a demo today at the Perth Modern Excel User Group at Microsoft Perth – its great.
Whilst it is a powerful editor, it is not just a code editor.
There are lots of options to allow you to optimise your DAX code. Lots of output options as well.
You can test and see how long it takes to run your DAX commands.
If you regularly use DAX in Power BI or PowerPivot then DAX Studio is a must have.
