Excel Formula & Function Assistance -- 2

I’m streamlining a series of files that live mostly as documents, yet the heavy lifting happens inside Microsoft Excel. I need an expert who can dive straight into my existing workbooks and build, refine, or replace formulas and functions so the sheets calculate everything accurately and automatically.

What this involves
• Reviewing the current layout and any sample data I provide
• Designing clear, maintainable formulas—think look-ups, nested IFs, conditional sums, date math, or whatever logic the job calls for
• Testing to be sure every cell returns the right result and scales as the data grows
• Adding brief in-sheet comments so I (and anyone else who opens the file) can understand the logic at a glance

I’ll send over the Excel files as soon as we start; you return a polished workbook with the new formulas in place plus a short note summarising the key changes. If additional tweaks pop up after initial delivery, I’m happy to handle those as a quick follow-up.
