Insert numbered cells + row based on cell value - excel

Question

I have managed to insert rows based on cell value for instance if A1 cell is 20, I run the macro, 20 rows appear under A1, those rows are blank right, I need the 20 new cells below A1 to be number 1 to 20 ( the number in A1) let me know if possible.
Cheers Adrien

Answer 1

Try this:
Sub counter()
Dim i as integer
for i = 2 to cells(1, 1) + 1
cells(i, 1) = i - 1
next i
End Sub

Answer 2

Insert an Integer Sequence Below a Cell
A Basic Example For the Active Sheet
Note that this doesn't insert rows, it just writes the integer sequence to the cells below A1.
Sub IntegersBelow()
With Range("A1")
.Resize(.Value).Offset(1).Value _
= .Worksheet.Evaluate("ROW(1:" & CStr(.Value) & ")")
End With
End Sub
Applied to Your Actual Use Case
Adjust the values in the constants section.
Sub InsertIntegersBelow()
' Use constants to change their values in one place instead
' of searching for them in the code (each may be used multiple times).
Const wsName As String = "Sheet1"
Const fRow As Long = 3
Const Col As String = "E"
' Reference the workbook ('wb').
Dim wb As Workbook: Set wb = ThisWorkbook ' workbook containing the code
' Reference the worksheet ('ws').
Dim ws As Worksheet: Set ws = wb.Worksheets(wsName)
' Calculate the last row ('lRow'),
' the row of the last non-empty cell in the column.
Dim lRow As Long: lRow = ws.Cells(ws.Rows.Count, Col).End(xlUp).Row
' Validate the last row.
If lRow < fRow Then
MsgBox "No data in column range.", vbInformation
Exit Sub
End If
Dim cCell As Range ' Current Cell
Dim cValue As Variant ' Current Cell Value
Dim r As Long ' Current Row
For r = lRow To fRow Step -1 ' loop backwards
Set cCell = ws.Cells(r, Col) ' reference the current cell...
cValue = cCell.Value ' ... and write its value to a variable
If VarType(cValue) = vbDouble Then ' is a number
cValue = CLng(cValue) ' ensure whole number
If cValue > 0 Then ' greater than 0
' Insert the rows.
cCell.Offset(1).Resize(cValue) _
.EntireRow.Insert xlShiftDown, xlFormatFromLeftOrAbove
With cCell.Offset(1).Resize(cValue)
' Write the values.
.Value = ws.Evaluate("ROW(1:" & cValue & ")")
' Apply formatting.
.ClearFormats
.Font.Bold = True
End With
'Else ' less than or equal to zero; do nothing
End If
'Else ' is not a number
End If
Next r
MsgBox "Rows inserted.", vbInformation
End Sub
