Dear All,

I need to select only 500 rows covering any range of the input sheet  (sampling) as attached here. The rows should be selected equally to cover the data range.

I need the first row and the last row and the rows between should be equally selected and moved the output sheet.

It is definitely possible to use some VBA macro to achieve this, but if you need only this I guess the fastest way will be manual work instead of looking for code and make .xlsb
Just press F5 in your Input sheet and type A1:B500 to select first 500 rows and copy-paste it into Output sheet.

I need to select 500 rows to cover the range. For example if I have 1000 rows then I should read the first row and skip the second and read the third and skip the fourth. So at the end I will be able to get 500 rows starting from the first row to the last row.

pls try

Sub Macro1()
' Macro1 Macro

LinesToBeSelected = 500
cnt = Range(Range("A1"), Range("A" & Rows.Count).End(xlUp)).Count
diff = cnt / LinesToBeSelected
For Idx = 1 + diff To (LinesToBeSelected - 1) * diff Step diff
    rw = Int(Idx)
    Union(Selection, Range(rw & ":" & rw)).Select
Selection.Copy Destination:=Sheets("Output").Range("A1")
End Sub

What do you want to happen if you have 1353 rows, such as in your data?
