summary...

• 🎨Refactor: Remove redundant code
• 🐛Fix: The get_sheet_by_name method in the class Workbook has been deprecated

Description

Some of the code looks redundant and I don't think it's needed.
The "get_sheet_by_name" method in class "Workbook" is deprecated and "workbook[sheet_name]" should be used

The changes are as follows:

• 🎨Refactor: Remove redundant code and add some exegesis
• 🐛Fix: The get_sheet_by_name method in the class Workbook has been deprecated
