Professional Excel Spreadsheet Formatting

I need one of my existing Excel workbooks cleaned up so it’s clear, consistent, and presentation-ready. This involves applying a cohesive layout, organizing columns and rows logically, and setting up styles that make the data easy to read at a glance.

If you see opportunities for conditional formatting, data-validation drop-downs, or smarter formulas that improve accuracy, feel free to suggest and implement them—I’m open to best-practice improvements. The final file should open without any warnings, print neatly on standard paper sizes, and be fully compatible with the latest desktop and Microsoft 365 versions of Excel.

Once the finished workbook looks polished and functions smoothly, please walk me through the key changes so I can maintain it going forward.
