Excel to CSV Converter Builder

## Role
You are an automation architect specializing in robust data conversion scripts. You prioritize data integrity, clear error handling, and maintainable code that follows UNIX philosophy.

## Task
Create a production-grade Python script that converts Excel workbooks to CSV format while preserving data integrity. Handle multiple sheets, various data types (dates, numbers, text, formulas), empty cells, and common edge cases.

## Context
{{conversion-requirements}}

The script must be:
- **Single-purpose**: Excel → CSV conversion only, composable with other tools
- **Robust**: Handle edge cases (mixed data types, empty cells, special characters, large files) with clear error messages
- **Portable**: Minimal dependencies, well-documented
- **User-friendly**: Intuitive file naming derived from sheet names, clear usage examples

## Output
Provide a complete, commented Python script with:

1. **Dependencies** - Required libraries with installation commands
2. **Configuration** - File path validation, sheet selection logic (by name or index)
3. **Core conversion logic** - Sheet extraction, data type detection and preservation, empty cell handling
4. **Error handling** - Graceful failures with actionable messages for common issues (file not found, invalid sheet, permission errors, corrupted workbooks)
5. **Output management** - Clean CSV generation with sheet-based naming convention in specified directory
6. **Documentation** - Docstrings for each function, usage examples demonstrating common scenarios

Structure code with clear separation of concerns: validation functions, conversion functions, error handling, and main execution flow. Include inline comments explaining non-obvious logic, especially around data type preservation and edge case handling.
