Formula to subtract one column from another

Posted on 2013-01-07

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.

Hi try
Sub add_workdays_formula()
    Dim c As Range
    For Each c In ActiveSheet.UsedRange.Columns(1).Cells
        If c <> 0 Then c.Offset(0, 7).Formula = "=networkdays(g" & c.Row & ",TODAY())"
    Next c
End Sub

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

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

Hi,

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())"

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

Sorry missed the "blanks" part. You can still do it without looping

Sheets("Sheet1").Range("H2:H" & Range("A" & Rows.Count).End(xlUp).Row).FormulaR1C1 = "=networkdays(rc[-1],today())"
Sheets("Sheet1").Range("A2:A" & Range("A" & Rows.Count).End(xlUp).Row).SpecialCells(xlCellTypeBlanks).Offset(, 7).ClearContents

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())"

Ok ssaqibh, no looping, one line, allows for formulas too, with same criteria for blank cells:

Union(ActiveSheet.UsedRange.Columns(1).SpecialCells(xlCellTypeFormulas), ActiveSheet.UsedRange.Columns(1).SpecialCells(xlCellTypeConstants)).Offset(0, 7).Formula = "=networkdays(rc[-1] ,TODAY())"

Any ideas to shorten?

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?

No, just the two lines posted in ID: 38753729

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.
