Audit a worksheet to find cells that should contain formulas but have hardcoded values
AI agents call excel_audit_calculations to retrieve information from Excel Finance MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool reads and inspects worksheet contents to identify cells with hardcoded values versus formulas. It is a purely analytical/read operation with no side effects — it does not modify, delete, or create any data.
