I'll create a responsive web interface for uploading and reading Excel files, specifically designed to work with the EBPs DATA SOURCE worksheet. The interface will allow users to select EBP values from a dropdown and view the complete row data.

I've created a comprehensive Excel file reader specifically designed for your EBPs DATA SOURCE worksheet. Here are the key features:

Key Features:

1. File Upload Interface: Clean drag-and-drop area that accepts only .xlsx files
2. Worksheet Validation: Specifically looks for the "EBPs DATA SOURCE" worksheet
3. Data Extraction: Reads rows 2-37 and extracts all column data
4. EBP Dropdown: Shows all unique EBP values from column B with category badges
5. Detailed Display: Shows complete row information in an organized, readable format
6. Responsive Design: Works perfectly on desktop, tablet, and mobile devices

How it Works:

1. Upload: Users drag and drop or click to select an Excel file
2. Processing: The app uses SheetJS to parse the file client-side (no server required)
3. Validation: Checks for the correct worksheet name and data structure
4. Selection: Users can choose from a dropdown of all EBP values
5. Display: Shows all associated data in organized cards with proper formatting

Data Display:

• Category badges (Clinical outcomes, Metabolites, Proteins) with color coding
• Action badges (Increase/Decrease) with appropriate colors
• Organized sections for Description, Associated Diseases, and Recommendations
• Proper formatting with line breaks and readable layouts

The interface handles errors gracefully, shows loading states, and provides clear feedback to users throughout the process. It's built with modern React patterns and uses shadcn/ui components for a professional appearance.
