I have about 5000 rows of data
I must insert nine blank rows between each two rows
this is the easy part till now....
then i want to fill these nine blank rows with series (linear-trend)

the problem that I want to fill each nine blank rows
seprately...because when i fill all the blank rows... they change the
values in the original rows !!!

so plz i want a macro to fill nine blanks rows then the next nine
blanks rows ! and so on ..

After you have inserted you 9 blank rows, then

Dim rng as Range, ar as Range
set rng = columns(1).SpecialCells(xlblanks)
for each ar in rng.Areas
' now ar should hold a reference to a set of 9 blank cells in column A
' you can use that to do your fill. It will then loop to the next set
of
' 9 blank cells
Next ar

sorry i can't get your point ...
here is the macro i use ,,,, plz clarify


Option Explicit
Sub InsertBlankRows()
Application.ScreenUpdating = False
Dim numRows As Integer
Dim r As Long
Dim Rng As Range
Dim lastrw As Long
numRows = InputBox("How many Rows")
lastrw = Cells(Rows.Count, "A").End(xlUp).Row
Set Rng = Range(Cells(1, "A"), Cells(lastrw, "A"))
For r = Rng.Rows.Count To 1 Step -1
Rng.Rows(r + 1).Resize(numRows).EntireRow.Insert
Next r
Application.ScreenUpdating = True
End Sub


thanks for your help

Rng.Rows(r + 1).Resize(numRows).EntireRow.Insert

Not much more I can tell you. Just saying serialize doesn't explain what
you are trying to do.

Didn't you already post about this and get a formula solution which you were
happy with. Use that. Just incorporate it in your code.
