What do I need to do to this VBA code so when I start it it applies to the
entire workbook rather than the worksheet?

Thank you.





Option Explicit

Sub KillRows()

Dim MyRange As Range, DelRange As Range, C As Range
Dim MatchString As String, SearchColumn As String, ActiveColumn As String
Dim FirstAddress As String, NullCheck As String
Dim AC

'Extract active column as text
AC = Split(ActiveCell.EntireColumn.Address(, False), ":")
ActiveColumn = AC(0)

SearchColumn = InputBox("Enter Search Column - press Cancel to exit
sub", "Row Delete Code", ActiveColumn)

On Error Resume Next
Set MyRange = Columns(SearchColumn)
On Error Goto 0

'If an invalid range is entered then exit
If MyRange Is Nothing Then Exit Sub

MatchString = InputBox("Enter Search string", "Row Delete Code",
ActiveCell.Value)
If MatchString = "" Then
NullCheck = InputBox("Do you really want to delete rows with empty
cells?" & vbNewLine & vbNewLine & _
"Type Yes to do so, else code will exit", "Caution", "No")
If NullCheck < "Yes" Then Exit Sub
End If

Application.ScreenUpdating = False

'to match the WHOLE text string
Set C = MyRange.Find(What:=MatchString, After:=MyRange.Cells(1),

If Not C Is Nothing Then
