## What the models said for it

- "Microsoft Excel | General‑purpose financial modeling | Dominant in finance, powerful formulas, Python in Excel, AI Copilot, wide ecosystem" (GLM 4.7 FlashX, Financial modeling)
- "Microsoft Excel or Google Sheets remain the practical sweet spot, offering functionality, familiarity, and affordability." (Claude Haiku 4.5, Financial modeling)
- "For many small businesses, the absolute best tool is the one you likely already own." (Qwen 3.7 Flash, Financial modeling)
- "includes options like Google Sheets or Excel, which are free or low-cost" (Llama 4 Maverick, Financial modeling)

## And against it

- "Heavy reliance on spreadsheets for consolidation. | Manual entry, broken formulas, copy‑paste errors, version‑control chaos, no audit trail. | A finance team that still reconciles intercompany balances in Excel." (GLM 4.7 FlashX, Financial consolidation)
- "Spreadsheets / Excel: sources warn they create data integrity, version-control, security, and compliance risks, and they are poor for large or complex lease portfolios." (Perplexity Sonar, Lease accounting)
- "Excel/Spreadsheets: They lack built-in audit controls, version history, and data validation, making them prone to errors, missed payments, and compliance issues." (Llama 4 Maverick, Lease accounting)
- "Excel-first workflows are the clearest avoid-or-caution category because they are manual, prone to user error, and inefficient for cash management at scale." (Perplexity Sonar, Cash flow forecasting)
