Excel/How to sum known columns with unknown rows using VBA
Would you be able to help me with this? I am using Excel 2007.
I have a workbook that contains multiple worksheets. Data in each worksheet has the same format, but the data range is different. The data always starts in cell N12 through cell O12, but the last row varies, e.g. the last row in sheet 1 is row 15, the last row in sheet 2 is row 20. I want to write VBA to accomplish the followings:
1. One row below the last row of the data, populate "TOTAL" in cell M?. ? represents the row number that is 1 + last row. For example, the last row in sheet 1 is 15. The "TOTAL" needs to be populated in cell M16.
2. Then sum column N staring from N12 to the last row of the data.
3. Then sum column O staring from O12 to the last row of the data.
4. Format the three cells montioned above with all boarders, arial font, and font size 8.
Thanks in advance for your help.
the following worked for me. It works on the sheets in the workbook that contains the code.
Dim sh As Worksheet, lastrow As Long, i As Long
For Each sh In ThisWorkbook.Worksheets
lastrow = sh.Cells(sh.Rows.Count, "N").End(xlUp).Row + 1
sh.Cells(lastrow, "M").Value = "TOTAL"
sh.Cells(lastrow, "N").Formula = "=Sum(N12:N" & lastrow - 1 & ")"
sh.Cells(lastrow, "O").Formula = "=Sum(O12:O" & lastrow - 1 & ")"
For i = 13 To 15
With sh.Cells(lastrow, i)
.Font.Name = "Arial"
.Font.Size = 8
