You're trying to create a macro that will insert a set of blank rows into an existing spreadsheet after each entry. The amount of needed rows will be the same for each entry of the spreadsheet, but will need to be changed each time it is used.
Here is a sample...
After using Macro:
The amount of blank row can go from 20 - 40.
A1 is having headings.
Then try this macro
keep your original file safely somewhere
first do the testing of macro in the experimental data you have sent
Dim j As Long, r As Range
j = InputBox("type the number of rows to be insered")
Set r = Range("A2")
Range(r.Offset(1, 0), r.Offset(j, 0)).EntireRow.Insert
Set r = Cells(r.Row + j + 1, 1)
If r.Offset(1, 0) = "" Then Exit Do
