Debugging Formulas with AI
You pasted a formula, and now you're staring at #REF!, #VALUE!, or #N/A. Instead of Googling error codes, ask AI to diagnose the problem.
The Debugging Template
When a formula isn't working, give AI everything:
- The formula that's failing
- The error you're seeing
- What the formula should do
- A sample of your data
Common Errors and How to Describe Them
#REF! Error
"My formula was working, but after I deleted column B, it shows #REF!"
#VALUE! Error
"I'm trying to multiply Column A by Column B, but I get #VALUE! Some cells in Column A have text like 'N/A' instead of numbers."
#N/A Error
"My VLOOKUP returns #N/A even though I can see the value exists in my lookup table. The lookup value is 'ABC123' and it's definitely in column A of my lookup range."
Circular Reference
"Excel says I have a circular reference. My formula in C2 is =A2+B2+C2. What's wrong?"
Pro Tip: Include Sample Data
The more context you give, the better:
Key Takeaway
AI is excellent at debugging because it can spot common mistakes instantly. Always include: the formula, the error, expected behavior, and sample data.
