## What the models said for it

- "If you want to project a company's budget/revenue, use Excel for flexibility, or Cube to automate it." (Gemini 3.5 Flash, Financial modeling)
- "If your company already pays for Microsoft 365, use Excel instead rather than buying another tool." (GPT-6 Luna, Financial modeling)
- "the best choice is usually Microsoft Excel if you need maximum flexibility at the lowest cost" (Perplexity Sonar, Financial modeling)
- "If you're on a tight budget, start with free tools (Excel, Wave, Cash Flow Frog, or Lunos)." (GLM 4.7 FlashX, Cash flow forecasting)

## And against it

- "Excel-based financial reporting "opens a company to a wide range of risks from data integrity issues, security vulnerabilities and version-control problems."→avoid spreadsheets as a system of record" (Muse Glimmer 30B, Financial reporting)
- "Spreadsheets like Excel or Google Sheets: they are widely used, but they are prone to manual data-entry errors, formula mistakes, and stale data, which makes them risky" (Perplexity Sonar, Cash flow forecasting)
- "Avoid using shared Excel files where multiple users have "Edit" access simultaneously. This overwrites audit trails and allows unauthorized changes." (Qwen 3.7 Flash, Internal controls)
- "many experts recommend phasing it out of primary reconciliation workflows due to its complexity, lack of scalability, and high risk of errors" (Mistral Small, Account reconciliation)
