Tom,

You have to use a loop to delete the names.

Dim Nm As Name
For Each Nm In ThisWorkbook.Names
If Nm.Name Like "Mark_??" Then
Nm.Delete
End If
Next Nm

Hi

I'd like to delete all name-objects that contain the caption "Mark_XX".
This
takes a very long time when more than 10'000 names of that kind are
available. Is there a faster way than doing it with a loop command?
