Power Query allows you to automatically perform data cleansing routines on your data sources – no manual intervention required. Simply refresh and your data is ready to use. You can use csv files; txt files; databases and existing Excel tables as your data sources. Learn the basics, plus an advanced technique to automate data cleansing routines on your data sources.

CPD note – if you are claiming CPD for watching this recording you need to keep your own records. People who attend the live sessions receive an annual listing of attendances.

This session covers

  • fixing dates so that Excel can recognise them
  • formatting columns as text – retaining leading zeroes in CSV files
  • deleting unwanted rows and columns from your data

DAX Functions

A listing of all the DAX functions with their syntax.

DAX functions are used in Power BI and PowerPivot for Excel.

It is a reference site, not a training site.

It has been created by Marco Russo and Alberto Ferrari – legends in Power BI and all things DAX.

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.

The R Language

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 Studio

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.
