COUNTBLANK

Counts the number of blank cells in a column.

What is the COUNTBLANK Function?

The COUNTBLANK function in DAX is like a meticulous inventory checker—it scans through a column and counts how many entries are blank or empty. This is especially useful for identifying gaps in your data that may need attention!

Example 1: Customer Feedback

Imagine you run a customer feedback survey and want to check how many customers did not leave feedback. Here’s how your feedback data might look:

To find out how many customers didn’t provide feedback, you’d use the COUNTBLANK function like this:

Blank Feedback Count = COUTNBLANK(Feedback[Feedback])

Total Blank Feedback Calculation:

• Emily: Good service! (not counted)
• Ace: (counted)
• Devin: Could improve. (not counted)
• Andrew: (counted)

So, how many customers didn’t leave feedback? That’s a total of 2 blanks! 📝

Example 2: Inventory Check

Now, let’s say you manage a warehouse and want to find out how many products don’t have a designated supplier. Here’s your inventory data:

To count how many products are missing supplier information, you would use COUNTBLANK:

Products Without Supplier = COUNTBLANK(Inventory [Supplier])

Total Blank Suppliers Calculation:

• Apples: Supplier A (not counted)
• Bananas: (counted)
• Oranges: Supplier B (not counted)
• Grapes: (counted)

So, how many products don’t have a designated supplier? That’s a total of 2 blanks! 📦
