Power Query: Steps to Take – Part 4
5 October 2022
Welcome to our Power Query blog. This week, I continue with my worked example by unpivoting and combining my data.
The tent business has a new administrative assistant, who used to work in the United States. George has provided some information, but it’s not yet in a format I can use:

In Part 1, I extracted the data and created a Base query, and took a Reference copy which I transformed to only hold the quantity rows: Quantities:

In Part 2, I created another query for the date information. This query is called Dates:

Last week, I transformed the data so that the dates are in the correct format for my region.

Now it’s time to put Quantities and Dates back together to get a list of dates and quantities. I need to get the dates and quantities in columns rather than rows first. To do this, I need to use the ‘Unpivot columns’ function. In Quantities, I select the Month column and right-click.

I choose to ‘Unpivot Other Columns’:

I need to perform the same unpivoting step in Dates:

I can now merge the data, using the Month and Attribute columns:

This brings my data back together:

I expand Dates to just give me the Value column:

Now I just need to tidy up. I only need the Value and Date.Value columns, which I rename Salespeople Available and Week Commencing. I also change the data type of Salespeople Available to Whole Number, and rename the query to Availability Q4.

The data is ready to load.
