Power Query lets you perform a series of steps to transform your Excel data.

There are times when we want to do things that are not built in the user interface. This is possible with Power Query’s programming language, which is M.

To start off, we will do a simple example of merging the first name and second name into a new column. This is possible with the CONCATENATE formula, however I want to use a simple example for you to get a feel of how to use M in Power Query.  Baby steps!

Let’s go through the steps in detail:

STEP 1: Select your data and turn it into an Excel Table by pressing the shortcut Ctrl + T or by going to Insert > Table

STEP 4: Let us create a simple M expression to combine the First Name and the Last Name.

In the New column name text box, type Full Name

In the Custom column formula, type in: [First Name]&” “&[Last Name] 

(You can alternatively double click in the Available columns names to use the column names in the formula)

The Ampersand (&) will combine the values together, then we added a space in the middle with the double quotes ” “

Click OK.
