Hello and welcome to Excel Power Query Advanced course.
At the outset I thank you for showing interest in this course.
In this video I will provide overview of all the contents of this course and what are basic requirements before you enroll into this course. So let’s get started.
There are four major areas I will be covering as part of this course. The first one is for troubleshooting the Power Query errors and workaround for limitation of Power Query. In real any software is not foolproof and has its own limitation. Also, if you don’t use the software as programmed you may encounter errors. And I hope you would agree that error codes or description in most of the software are not that user friendly or they do not provide appropriate solution to resolve the error. Hence in this first section I will show some of the common areas where you face Power Query limitation and errors. Some of them are as follows:
Error encountered with adding / rename / deleting a particular column headings.
Handling null values during arithmetic calculation.
Identify error rows encountered while creating or on refresh of query.
Multiplying effect when you JOIN queries
Issues with filters and how to use advanced filters.
Then the next area is for advanced case studies. Similar to my starter course of Excel Power Query where I have shown you more than 20+ real life case studies of applying power query, here also I have taken some real life case studies which require some more in depth knowledge of Power Query and workaround. This section will be updated new case studies as and when I see some interesting datasets. The current video are related to :
Applying local setting when converting the dates fields
Leave dataset which needed leave details to be broken into separate rows from a single cell.
Unstack the dataset which has uneven details
Combine multiple rows data back to single cell.
Then next section is for advanced M concepts. Here I will give you more information related to M Language in Power Query. What syntax is to be used under advanced editor. How to create parameters and use it inside your power query. How to create new custom M function using PQ interface or through advanced editor. I will also show how you can troubleshoot the custom M function you have created using advanced editor. Then I will show you how you can organize your multiple queries in separate groups. Further I will also show how to use Query Dependency view which will give you visual presentation of all the queries inside your excel file. This will help you understand the flow of all the data from source till the final output, where it is loaded or which queries are referenced to each other. All precedents and dependents to your queries can be easily identified.
And now finally in last section I will be providing some ready made patterns for power query. I will provide all the power query code which you can copy paste into your file and start using it. You will not need to create any new query for these patterns. Since creating these patterns using power query requires lot of efforts and also very complex I am providing you these as ready to use.
So now before you enroll I would like to tell you that there are few requirements.
First one is that you should have latest version of Power Query installed if you are using Excel 2010 / 2013 or if you are using Excel 2016 then it should be updated.
Second and most important is that you should have prior knowledge of using Power Query.
So that is it. There are no further requirements other than these two. So what are you waiting for, enroll now into the course.
