I have attached a snipet (the spreadsheets will range from 300 rows to 3500 rows) from a spreadsheet that I need to have vba code in a macro that will perform the formulas in the highlighted cells. It will need to insert the three blank columns, run the formulas, highlight the columns and also total at the bottom of those columns. I am going to have to do this on 125 spreadsheets so it would be very helpful if I have a Macro to run as I pull each one up. Any help will be appreciated. Thank you.
