excel-vba-refactoring

What problem does it solve?

This Skill provides a comprehensive methodology for refactoring and modernizing legacy Excel VBA projects, turning brittle, monolithic code into modular, maintainable architectures.

Core Features & Use Cases

• Modular Architecture: Introduces centralized constants, clear module boundaries, and scalable patterns for large VBA projects.
• Standardized Practices: Provides standardized error handling, validation, and auditing patterns to improve reliability.
• Advanced Capabilities: Covers working mode systems, status migration strategies, and database-like patterns with referential data management across workbooks.
• Use Case: You have an aging Excel VBA workbook with multiple interdependent sheets; this Skill guides you to structure code, migrate statuses, and implement safe concurrent editing workflows.

Quick Start

Begin by reviewing the core patterns in references/ to understand constants, error handling, and working-mode implementations; then initialize a refactoring plan that creates mod_Constants, mod_Utilities, and a new status management approach across workbook modules.
