Excel Macro Automation Developer

I already keep all of our operational data in a single Excel workbook, yet every update still forces me to run lengthy formulas by hand. I now want that entire data-processing chain—especially the complex calculations—wrapped into clean, reliable VBA macros.

Here is what I need the finished workbook to do:

• One click (or a keyboard shortcut) should trigger the macro, pull the latest raw data, run every nested lookup, conditional formula, and aggregation step, then write the results back to the summary sheet.
• Calculations must replicate our current results exactly while finishing noticeably faster.
• Code has to be fully commented, logically structured, and easy for me to tweak later.

Deliverables
1. Locked-in VBA module(s) containing the automated procedures.
2. Workbook updated with buttons or ribbon shortcuts that launch each macro.
3. A brief hand-over note or screen-share call walking me through the logic so I can maintain it.

Once the macro passes a quick accuracy check on a 20 000-row test file, the job is done. In your proposal, please mention one comparable project you have completed and how soon you could get started; I’m ready to move forward immediately.
