ChatGPT prompt for reconciling two Excel lists with duplicates and near matches

Excel data reconciliation Intermediate 🤖 ChatGPT 👁 4 views

📝 The Prompt

I need to reconcile two Excel lists that should overlap, but the data is messy. Act like an operations analyst who specializes in spreadsheet reconciliation. List A details: - Source: [CRM/export/system] - Key columns: [paste columns] List B details: - Source: [ERP/billing/export/system] - Key columns: [paste columns] Problems I am seeing: - Duplicates: [yes/no + examples] - Name variations: [yes/no + examples] - Missing IDs: [yes/no] - Date or amount differences: [yes/no] Please provide: 1. A practical reconciliation workflow in Excel from raw data to final exception list. 2. The best formulas to use first, including XLOOKUP, COUNTIFS, TEXT functions, and any helper columns. 3. A method for identifying exact matches, likely matches, and unmatched records. 4. A final review sheet layout I can share with a manager. 5. Advice on when to stop forcing Excel and switch to Power Query or another tool. Format the answer with sample formulas and clearly named helper columns. Optimize for speed and accuracy, not theory.

⚙️ Replace 5 placeholders: [CRM/export/system] [paste columns] [ERP/billing/export/system] [yes/no + examples] [yes/no]

  1. Copy the prompt using the 📋 button above.
  2. Open ChatGPT (or Claude, Gemini, Perplexity, or your preferred LLM).
  3. Paste the prompt into a new chat. Replace 5 bracketed placeholders ([CRM/export/system] [paste columns] [ERP/billing/export/system] ) with your own details.
  4. Run the prompt and review the AI's response. Most outputs are usable immediately.
  5. Iterate if needed — if the tone, length, or structure isn't quite right, reply with "make it shorter", "use bullet points", or "make it more formal" and the AI will refine it.

💡 Tips for better results

  • Replace the bracketed placeholders ([CRM/export/system], [paste columns], [ERP/billing/export/system], [yes/no + examples]) with your own specifics before sending.
  • If the first output isn't quite right, ask the AI to refine, rewrite, or add more detail — iteration is key.
  • For long outputs, ask for a section at a time (e.g. 'start with the introduction only') to keep quality high.
  • Combine this with other excel prompts to build an end-to-end workflow.
  • Save your favorite variations — small wording tweaks often produce noticeably different results.
