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.
Unfortunately not all of Excel’s formulas can be used in M.
For example, if we want to use the RIGHT Excel Function, it is not supported in M.
But I will show you how we can replicate the RIGHT Function in M using Power Query and the Text.End formula!
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 2: Go to Data > Get & Transform > From Table (Excel 2016) or Power Query > Excel Data > From Table (Excel 2013 & 2010)
Excel 2013 & 2010:
STEP 3: This will open up the Power Query Editor.
Select the SALES QTR column.
Go to Add Column > Add Custom Column
STEP 4: We want to get the last character of the SALES QTR cell values. For example: 1, 2, 3 or 4
So, let us create a simple M expression to replicate the RIGHT function in Excel.
In the New column name text box, type SALES QTR (Shortened)
In the Custom column formula, type in: Text.End(
From the Available columns choose SALES QTR and Insert
Then finish off the formula by entering , 1)
We now have built the following formula:
Text.End([SALES QTR], 1)
So let us quickly break down what we just did:
- We are using the Text.End formula to get the last X characters of the SALES QTR column
- We place in 1, to specify that we want the last 1 character.
Click OK to confirm.
Now you will see your changes take place.
STEP 5: Click Close & Load from the Home tab and this will open up a brand new worksheet in your Excel workbook with the updated values.
Congratulations! You have used a M formula for replicating the RIGHT function!
