What Does #SPILL Mean in Excel 📊

Hey! 😅 I was working on my Excel sheet the other day, and suddenly I saw #SPILL pop up in one of my cells.

At first, I had no idea what it meant, and honestly, I panicked a little. I kept thinking, Did I break something?

But then I realized it’s actually Excel’s way of telling me that my formula is trying to return multiple values, but something is blocking it.

I had to figure out which cells were in the way and adjust my formula. Let me tell you exactly how I handled it…

🧠 What Does #SPILL Mean in Excel?

#SPILL is an Excel error that appears when a formula that’s supposed to return multiple results (an array) can’t “spill” all its values into the necessary cells. Simply put, Excel is saying: “I have more results than the space you gave me.”

Example:
Typing =SEQUENCE(5) in cell A1 should fill A1:A5 with numbers 1 to 5. If there’s something blocking A2, A3, etc., Excel shows #SPILL! in A1 instead.

In short:
#SPILL = Formula cannot output full array = Need more space or remove obstacles.
