Power Query: Blog List – Part 1
29 November 2023
Welcome to our Power Query blog. I would like to get a list of all the Power Query blogs I have posted. Today, I begin by extracting data from the first page.
I started writing this blog series way back in 2016:
There have been many developments since then, some of which I have already reported upon. Since I am going to revisit some more of the areas that have been improved, I am going to start with a reminder of what we have covered so far. In order to do this, I am going to use Power Query in Power BI, since there are some functions that will help me to access web data, which are not yet recognised in Power Query (Get & Transform) in Excel.
I open a new Power BI desktop session and access the ‘Get Data’ dialog. I then search for ‘web’:
The URL that I will need is from this page:
However, before I continue, I note that to get a full list, I am going to need several pages:
The first step, which I will cover this week, is to get one page. To do this, I access the ‘From Web’ dialog and input the URL:
When I click ‘OK’, I am taken to the Navigator dialog:
Table1 contains the data I need, so I select that and click ‘Transform Data’.
I will tidy up the data for this page. I start by using ‘Choose Columns’ from the Home tab.
I would like to keep everything apart from Column4. I would also like to sort the blogs in ascending date order:
I rename the columns to something more useful:
I choose to remove the beginning of the Description information. To achieve this, I use the Extract dropdown from the Transform tab:
I would like to keep everything after the first comma (,).
This removes the repetitive information.
Now I am happy with this page of data. Next time, I need to consider how to access the other pages.
Come back next time for more ways to use Power Query!
