Simple Excel Calculation Macro

I need a lightweight VBA macro that opens with a single shortcut and runs automated calculations across my worksheet. The emphasis is on speed and reliability—no bulky dashboards or multi-sheet reports—just the calculations I specify and a quick finish.

Alongside the calculations, the macro should tidy things up by applying basic cell formatting. I am not looking for duplicate removal or gap-filling routines; the only data-cleaning touch I need is that formatting step. My note for the exact formatting reads “Cerate calculations,” which simply means the formatting must work hand-in-hand with the calculation logic you write so results are clear and easy to read.

Deliverable: one ready-to-import .bas (or .xlsm) file with well-commented code plus a brief usage note so I can adapt ranges or formulas later. Once I drop it into my workbook and hit the shortcut, the macro should perform the calculations and formatting in a single pass without errors.
