What problem does it solve?

This Skill automates Microsoft Excel on macOS, helping you reliably generate, read, and update spreadsheets without slow, cell-by-cell manual work.

Core Features & Use Cases

• JXA-first Excel automation: Use JavaScript for Automation to drive Excel via Apple Events with Excel-specific defensive patterns.
• High-performance bulk range operations: Read and write ranges using correct 2D array (list-of-lists) shapes to avoid IPC latency and type mismatches.
• VBA escape hatch for coverage gaps: Invoke existing VBA macros when JXA support is brittle or incomplete (e.g., pivots, advanced charts).
• Use case: If you need to apply the same transformation (like updating prices, recalculating totals, or reshaping report data) across many workbooks, use this Skill to bulk-process ranges and keep data integrity across sessions.

Quick Start

Ask: “Using JXA Excel automation, open my workbook, read the used range from the first sheet as a 2D array, apply a transformation to a numeric column, and write the updated 2D array back in one bulk operation.”
