This page provides a basic overview, but, there is a key link if you scroll down a bit called Power Query formula categories as shown below.Ĭlick this link and you find the Power Query M function reference page, shown below. We click the Learn about Power Query formulas link in the Custom Column dialog and up pops the help page, as shown below. Now, at this point, we have no idea about which M function can help, or, if there even is one. ![]() This opens the Custom Dialog, as shown below. Second, we need to create a new custom column by clicking Add Column > Custom Column. ![]() To do this, we select the Zip column and then click Transform > Data Type > Text. Let’s give that option a try.įirst, we need to change the data type of the Zip column from a number to a text. And yet another possibility is to use a built-in M function that is designed exactly for this purpose. Another possibility is to send the results to Excel as they are, and then handle the formatting in Excel with a custom 00000 format. One option would be to do a Conditional Column, where we try to determine the length of the zip and concatenate a leading zero if the length is 4. As we click through them, searching the Format command, Fill, Replace Values, Data Type, Extract, Column from Examples, Standard, and more, we can’t seem to find anything that will work. If you are like me, your first instinct is to start exploring the command icons. As with just about anything, there are multiple ways to accomplish this task. For example, instead of 2914 we want 02914. Now, we’d like our Zip column to display a leading zero when needed. With our data in PQ, it is time for the next step.

Not all PQ functions are available in the ribbon. We search through the Query Editor ribbon, click all the icons, right-click everyplace we can think of, and nothing. We can’t seem to find a command that will format the zip codes with leading zeros. We are able to accomplish everything we need by clicking command icons, and we are almost done … except for one little thing. Let’s say we are using Power Query to import and clean some data. Objectiveīefore we get too far, let’s confirm our goal here. In this post, I’ll illustrate this by adding leading zeros to a zip code. So, the thing to keep in mind is that if you are trying to accomplish something, and don’t see a command icon, dig into the functions because there is a good chance you’ll find something helpful. M code has many more functions than are available in the ribbon. ![]() In the Power Query Editor, as you click the command icons, Excel is actually writing M code behind the scenes. Whenever you add something new to the source table, right-click on the output table and select Refresh to update it.Power Query is an amazing tool, and I love learning about it.
