Is there an AI Excel formula checker?
Paste the broken formula into a chat AI, along with the error and what you wanted it to do. It finds the mistake, hands back a fixed formula, and tells you what was wrong.
Formula, error, what you expected.
Copy the whole formula
From the equals sign to the last bracket.
Include the error
#N/A, #VALUE! and #REF! mean different things.
Say what you expected
"It should be 450. It says 0."
Ask what went wrong
So you spot it next time.
