GridCraft Gives Claude Spreadsheet Control

GridCraft’s compelling idea is not merely replacing Excel—it makes spreadsheet state programmable for AI agents. The demo is impressive, but production reliability still trails the automation vision.

• –MCP supports both headless workbook sessions and control of an open desktop window.
• –XLSX compatibility, dynamic arrays, LET, LAMBDA, charts, and PivotTables make it useful beyond toy demos.
• –Local execution, open-source licensing, and no telemetry reduce privacy and deployment concerns.
• –The project still flags large workbooks, complex file fidelity, circular references, and legacy `.xls` support as limitations.
• –Agent-driven spreadsheets will need strong review, undo, and audit workflows before teams trust them with financial models.
