In order to enter formulas in Excels with a macro, you will need to open your spreadsheet. Formulas are used to do calculations. Go to the field, where you want to enter a formula. Type in the formula. Then, highlight the formula. Press Control + C to copy the formula. Next, delete the contents of the cell. Press Alt + F11. The shortcuts that you will be using are Alt + F11 for VBA window and Alt + F8 to view macros. Select the workbook, insert, and module. Enter this macro: Sub Enter_Formulas() range("D4").Formula = "[insert the formula that you copied earlier]" End Sub. Go back to your spreadsheet. Press F8. You can also extend the range beyond that cell, if you like.
