There was a problem hiding this comment.
The PR introduces a solid foundation for the cat_xlsx command. The code is well-structured and uses modern Rust practices with clap for argument parsing. However, it could benefit from more robust error handling and user feedback. Consider adding configuration options for output format in future iterations, and adding tests to ensure reliability. The README provides basic usage information but could be enhanced with examples of the output format and more detailed usage scenarios.

- Print an error message and exit with code 1 if the file is not found - Validate file extension and print an error message if it does not have the .xlsx extension
- Follow cargo clippy suggestion: - Use `is_some_and` instead of `map_or` to validate the file extension - Print an error message and exit if the file extension is not `.xlsx`
