# Formula to subtract one column from another

Hi,

I need to put a formula into a blank column that subtracts the date in another column from Today and returns the number of workdays. This is a line in a VBA macro.

The catch is that it need to do it for every row where column A is not "blank/null".

To restate, every row where column A is not blank, subtract the date from column G and insert the number of workdays into column H.

I think it might start something like this?

Sheets("Sheet1").Range("H2:H" & Range("A2").End(xlDown).Row).FormulaR1C1 = "=?"

I'm just not sure what should be where the =? is. I couldn't say "=Today()-G" without specifying a row# right?

Any help would be appreciated.

The NETWORKDAYS function can also include holidays if you have them in a list in your worksheet, do you want to do that?

Sheets("Sheet1").Range("H2:H" & Range("A2").End(xlDown).Row).FormulaR1C1 = "=today()-rc[-1]"

By the way did you want workdays ie number of days excluding weekends? Or just the total number of days

Needed number of days excluding weekends.

Looks like some good possibilities posted but i'll have to wait till the morning to try them.

Thanks very much,

To exclude networkdays you can use networkdays as suggested by terencino.

The modified statement would be

Sheets("Sheet1").Range("H2:H" & Range("A2").End(xlDown).Row).FormulaR1C1 = "=networkdays(rc[-1],today())"

The modified statement would be

Sheets("Sheet1").Range("H2

Note that this formula

Sheets("Sheet1").Range("H2:H" & Range("A2").End(xlDown).Row).FormulaR1C1

will put a formula in

The code I sent you will only put a formula where there is a value in column A

Sheets("Sheet1").Range("H2

will put a formula in

__every__cell.

The code I sent you will only put a formula where there is a value in column A

You can also use this one-liner if the entries in column A are values and the blanks are blanks cells (Not "" entries)

Sheets("Sheet1").Range("A2:A" & Range("A" & Rows.Count).End(xlUp).Row).SpecialCells(xlCellTypeConstants).Offset(, 7).FormulaR1C1 = "=networkdays(rc[-1],today())"

Sheets("Sheet1").Range("A2

Maybe not but for such a case I personally would prefer the two-liner which I have already proposed. But the key constraint here is that the blanks cells MUST be really blank and not blank by formula.

So you would need three lines then if column A included formulas? And if blanks in column A were not genuine blanks then you would need to loop through as I originally proposed to test column A cells against various criteria?

And if blanks in column A were not genuine blanks then you would need to loop through as I originally proposed to test column A cells against various criteria?True

Both solutions awarded worked. The report I'm working with comes off a server so blanks are really blank but nice to have the answer if/when they're not!

Thanks for your help. I sincerely appreciate it.
