Is there a way to make an entire column have a formula? I'm exporting data into an excel sheet, and I need one column (J) to have a formula in it from cell 1-65536. I know that you can go for example: (=$H2-$I2) and drag that all the way down. But this fills all the blank columns with 0's and when I go to print it, it prints like 2500 sheets of 0's. Any idea how to set a formula for an entire column?
