Transposing a data set is ultimately rotating data from rows to columns, or from columns to rows. To understand this concept, an example with the picture is given below.

Transposing Data By Power Query

Let’s go through the steps in detail for transposing data.

Step 1: Open the data in Power Query

Open the data set in Power Query that you want to transpose. The picture below shows the data that we want to transpose. We will transpose this data to rotate it from rows to columns.

Step 2: Transpose the data table

 Select Transform > Transpose

It flips the data from rows to columns. Power BI Transpose option works on the entire Data table as shown in the below picture.

Note: When you transpose the data table, it eliminates the existing column headers and replaces it with the default                     Power Query column headers like Column1, Column2….and so on.

Step 3: Use first rows as headers

Go to Transform > Use First Row as Headers button > Use First Row as Headers option

This will show all the details of individuals column-wise.

Step 4: Close & Apply

Click Close & Apply from the Home tab and this will apply all the pending changes on your transposed data.
