Excel formula troubleshooting Beginner 🤖 ChatGPT 👁 15 views

📝 The Prompt

Act as a senior Excel troubleshooting expert. I have a workbook where lookup formulas are failing across multiple sheets. Some cells return #N/A, #VALUE!, or the wrong match. Help me diagnose and fix the problem systematically. What I need from you: 1. Ask me for the exact lookup formula, sample data from both sheets, and the expected result. 2. Check for the most likely causes, including: - text vs number mismatches - extra spaces or hidden characters - wrong match mode - broken references after columns were moved - duplicate lookup keys - formatted values that only look identical 3. Recommend the best formula approach using XLOOKUP first, then INDEX/MATCH as fallback. 4. Provide corrected formulas and explain why they work. 5. Show helper formulas to test whether the source values truly match. 6. Suggest a clean way to make the workbook more resilient so the issue does not keep happening. Response requirements: - Use plain English - Give copy-paste-ready formulas - Include a short “debug checklist” I can reuse in future workbooks
