Excel Macro Development

I want to replace a string of repetitive, error-prone steps in my workbook with a clean, well-documented VBA macro. The end result should run at the click of a button or a keyboard shortcut, carry out every step automatically, and leave the sheet ready for review without any manual fixes.

Deliverables
• The Excel file containing your fully commented VBA code
• A short note (or Loom/video) explaining how to install, edit, and trigger the macro in Excel 2016, 2019, and Office 365
• Clear documentation of any external references or libraries you use

Acceptance criteria
• Macro executes from a single action with no run-time errors
• Code is logically structured and easy for me to tweak later
• Operation remains consistent across all three Excel versions mentioned

Please outline your proposed approach, any questions you need answered first, and a rough timeline to completion.
