Excel Font & Color Formatting

I have an existing Excel workbook that only needs light cosmetic work—changing font sizes and applying a clean, black-and-white colour scheme. I’m still deciding whether every sheet should share one uniform size or if headers, sub-headers, and body text deserve their own, so I’ll need your quick advice before you start.

Once we agree on the sizing approach, you’ll:
• Apply the chosen font sizes exactly where they belong.
• Keep all text strictly in standard black or white.
• Leave every formula, layout element, and piece of data untouched.

Return the same workbook with the visual polish complete and I’ll confirm everything matches the agreed-upon hierarchy. Straightforward task for anyone fluent in Excel’s formatting tools.
