• Clean typography and spacing
• Subtle gradients and shadows
• Professional table styling
• Clear visual hierarchy

This version focuses on functionality and readability without the vibrant color schemes, perfect for professional or business applications!

I'll refactor the code into clean, reusable components with better organization:

Now the code is much cleaner and well-organized! Here's what I've improved:

️ Component Architecture:

1. types/excel.ts - All TypeScript interfaces in one place
2. hooks/useExcelProcessor.ts - Custom hook for Excel processing logic
3. utils/excelTemplates.ts - Utility functions for template generation

4. components/ - Modular, reusable components:

   • file-upload.tsx - File upload functionality
   • file-info.tsx - File information display
   • loading-spinner.tsx - Loading state component
   • worksheet-table.tsx - Table display logic
   • worksheet-card.tsx - Individual worksheet card
   • summary-stats.tsx - Statistics display
   • worksheets-display.tsx - Container for all worksheets

Benefits of This Structure:

1. Separation of Concerns - Each component has a single responsibility
2. Reusability - Components can be easily reused in other parts of the app
3. Maintainability - Easy to find and modify specific functionality
4. Type Safety - Comprehensive TypeScript interfaces
5. Testability - Each component can be tested independently
6. Clean Code - No more massive single file with everything mixed together

Key Improvements:

• Custom Hook - useExcelProcessor handles all Excel processing logic
• Utility Functions - Template generation moved to separate utility
• Props Interfaces - Clear contracts between components
• Error Handling - Centralized error management
• State Management - Clean state flow between components

The main component is now much simpler and focuses only on orchestrating the other components!
