Question

Ive written a macro that takes some source data and writes it onto several sheets, which id like to remain hidden before and after the macro has run. Having written the Macro, when I run it it only updates a few records on each sheet (for instance on the first hidden sheet it updates 21 rows out of over 1000. What is the reason for this happening? Surely it should update them all or none of them? Im not getting any errors either. Ive tried

Application.ScreenUpdating = False
Worksheets("FT Raw").Visible = True
Worksheets("L1").Visible = True
Worksheets("L2").Visible = True
Worksheets("L3").Visible = True
Worksheets("L4").Visible = True

But still only 21 rows get updated.

Update: This is the code that is running on each sheet

endval = Cells(Rows.Count, 1).End(xlUp).Row

For i = 1 To endval
    If Not Sheets("FT Raw").Cells(i, "A") = "" Then
        splitted = Split(Sheets("FT Raw").Cells(i, "A"), ",")
        Sheets("FT Raw").Cells(i, "B") = splitted(0)
        Sheets("FT Raw").Cells(i, "C") = splitted(1)
        Sheets("FT Raw").Cells(i, "D") = splitted(2)
        If Sheets("FT Raw").Cells(i, "D") = "1" Then
            Sheets("L1").Cells(j, "A") = Trim(splitted(0))
            Sheets("L1").Cells(j, "B") = Trim(splitted(3))
            j = j + 1
        End If
    End If
Next i

Ok Edit. You need to specify the Sheet(“FT Raw”) in your endval calc.

Try this set endval = Sheets("FT Raw").Cells(Sheets("FT Raw").Rows.Count, 1).End(xlUp).Row and proceed with the remainder of your code.

(You could also use endval = Sheets("FT Raw").UsedRange.Rows.Count only if you don’t have blank cells at the top of the column)

Lucky last, you don’t have to unhide these sheets at all to run the code. By all means do so to debug but when running in anger it’s not necessary.
