Excel Spreadsheet (.xlsx) Guide

This guide covers creating, editing, and analyzing Excel files with a focus on formula-based calculations and professional formatting.

Critical Requirements

Zero Formula Errors

All deliverables must have ZERO formula errors:

• #REF! - Invalid cell references
• #DIV/0! - Division by zero
• #VALUE! - Wrong data type
• #N/A - Value not available
• #NAME? - Unrecognized formula name

Use Formulas, Not Hardcoded Values

Always use Excel formulas instead of calculating values in Python.
