Analyze and document unfamiliar spreadsheets with Claude
This technique lets you audit complicated or inherited spreadsheets using Claude before modifying any data. The workflow identifies hidden formulas, unwritten assumptions, and potential calculation risks without altering the original workbook.
Try it yourself
- 1Create a backup copy of the original spreadsheet file to work on.
- 2Prompt the AI model to explain tab structures and identify unwritten logic without editing the document.
- 3Verify each flagged area manually or consult with the original file owner.
- 4Adjust a single test variable in your working copy to confirm calculations update across all tabs properly.
Copy this prompt
I inherited this spreadsheet and need to understand it before changing anything. Don't edit it. 1. Explain how the tabs connect and what each key formula does. 2. List anything undocumented, hidden, hardcoded where neighboring cells are formulas, or linked to outside files. 3. Give me an issue log: cell, what's wrong, which outputs it affects, and High, Medium, or Low risk.
