What is Preserved

Chat History Not Saved

Best Practices
To use Claude effectively and safely in financial workflows, follow these practices. Click each to expand details.
Always Review Changes Before Finalizing
Claude is highly capable but operates as an assistant, not a replacement for human judgment. Always review the changes Claude makes to formulas, data, and formatting before presenting outputs to stakeholders or using them in business decisions.
Validate Outputs Against Business Logic
Cross-check Claude's outputs against your understanding of the business. If a financial model produces numbers that seem unrealistic, investigate before accepting them. Claude provides analytical support — your domain knowledge provides the final validation.
Use Secure and Trusted Data Sources
Ensure that any data you work with in Claude for Excel comes from trusted, controlled sources. Avoid uploading files that contain personally identifiable information or highly sensitive financial data without appropriate controls in place.
Maintain Human Oversight for Critical Work
For any analysis that will inform major financial decisions — board presentations, investor reporting, M&A due diligence — treat Claude's outputs as a first draft that requires expert review, not a final deliverable.
