There are some instances that we wish to add a number one zero to a digit, reminiscent of exhibiting 01 as a substitute of 1, 02 as a substitute of 2 and so forth. We now have two choices to do that in Energy BI, doing it in Energy Question or doing it with DAX.
Including a Main Zero in Energy Question
The primary methodology is doing it in Energy Question utilizing the
Textual content.PadStart() perform.
Right here is how the syntax of the perform:
Textual content.PadStart(textual content as nullable textual content, depend as quantity, optionally available character as nullable textual content)
And right here is how the perform works:
Textual content.PadStart(enter string, the size of the string, an optionally available character to be added to the start of the string util we attain to the string size)
Textual content.PadStart("12345", 10 , "a") returns
Textual content.PadStart("1", 2 , "0") returns
Let’s create a listing of integer values between 1 to twenty with the next expression:
Now we convert the record to a desk by clicking the To Desk button from the Remodel tab:
Now we add a brand new column by clicking the Customized Column from the Add Column tab from the ribbon bar:
Now we use the next expression within the Customized Column window to pad the numbers with a number one zero:
Textual content.PadStart(Textual content.From([Number]), 2, "0")
Listed here are the outcomes:
And the final step is to right the columns’ knowledge varieties by choosing all columns (press CTRL + A) then clicking the Detect Information Kind button from the Remodel tab from the ribbon.
Ultimately we click on Shut & Apply to load the information into the information mannequin.
Including a Main Zero with DAX
I’m a giant fan of taking good care of any kind of transformation actions in Energy Question. However, in some instances, we wish to add a number one zero to a quantity simply to format the quantity. I imply, including a number one zero to numbers just isn’t essentially a change exercise. Chances are you’ll wish to pad the outcomes of a measure with a number one zero if the quantity is between 0 and 10. The next methodology works regardless although. And… it is rather easy. Easier than you suppose. We simply want to make use of the
FORMAT() perform in DAX. The output of the perform is a string.
The syntax of the FORMAT features is:
And right here is how the perform works:
FORMAT(a single worth or an expression that returns a single worth, a format string)
The formatting template of the perform is the place all of the magic occurs. There’s a variety of formatting templates together with predefined ones and customized formatting.
Right here is how we pad a number one zero with DAX:
FORMAT(<a numeric worth>, "0#")
We simply want to make use of the above sample in our calculations both within the calculated columns or measures. In our instance, we add a calculated column, so right here is the DAX expression for the calculated column:
Quantity with Main Zero in DAX = FORMAT('Main Zero'[Number], "0#")
However wait, what if our record of numbers ranging from 0? Let’s change our pattern knowledge in Energy Question so the record begins from 0, and cargo the information into the mannequin once more. Here’s what we get:
Hmm! That doesn’t look good!
Right here is the answer in Energy Question:
if [Number] = 0 then "0" else Textual content.PadStart(Textual content.From([Number]), 2, "0")
Chances are you’ll suppose that we are able to use the identical logic in DAX utilizing
IF() perform, which we undoubtedly can, however wait; I wish to present you a greater trick. Right here is the DAX expression with out utilizing
Quantity with Main Zero in DAX = FORMAT('Main Zero'[Number], "0#;;0")
Every format string can have as much as 4 sections. We are able to separate every formatting part utilizing a semicolon (;). If the format string has one part then it applies to all values, in any other case:
- The primary part applies to optimistic values
- The second part applies to damaging values
- The third part applies to zeros
- The forth part applies to
So, the format string of the latter DAX expression (
"0#;;0") add a number one zero to every integer worth, but when the worth is zero, then it reveals zero.

There’s one other situation that won’t even require including a brand new calculated column with padded values. Suppose you’ve got a desk with an Index column, identical to what I’ve within the above instance and I simply wish to present the padded values. In that case, I don’t even want so as to add a calculated column. Certainly, I can format the Quantity column to indicate the padded integer values. Let’s see how it’s potential:
- Choose the Quantity column
- Use the next formatting string within the Format dropdown of the Formatting part from the Column instruments from the ribbon
That is very cool, once we format values, we’re not altering the information sort. So after formatting the values, they’re nonetheless numeric values, which in my instance it’s Complete Quantity.
This bonus is for individuals who learn this text by way of the top. Do you know that you could convert integer date values to Date utilizing the
FORMAT() perform reminiscent of changing 20210910 to 10/09/2021?
Right here it’s:
