Increase Speed

[SIGE_GOEVAERTS]

Hi There,

Normally underneath macro runs quite smoothly.
But sometimes this macro takes ages to complete...not that it bugs but
the calculation speed is like litterally 100 times slower. (for the
same range-sizes!)
All I can do is Close Excel and restart the marco ... to let it run at
normal speed.
Any Ideas? -For Improvement?

Option Explicit

Sub BlanksToNumbers()
Dim r As Range
Dim w As Worksheet
On Error GoTo err
Application.ScreenUpdating = False
For Each w In ActiveWorkbook.Worksheets
For Each r In w.UsedRange.Cells
r.Cells.Font.Name = "Arial"
If r.Text = "" And r.Formula = "" Then r.Value = ""
Next r
Next w
Application.ScreenUpdating = True
err:
End Sub

Cheers, Sige

this should change the font for the entire workbook which should be better
than changing part of each worksheet.

Sub changefontinworkbook()
Sheets.Select
Sheets(1).Activate
Cells.Select
With Selection.Font
.Name = "arial"
End With
Range("A1").Select
Sheets(1).Select
End Sub

or
Sub chgfontname()
Sheets.Select
Cells.Select
Selection.Font.Name = "arial"
Range("a1").Select
Sheets(1).Select
End Sub

or for speed, skip the selecting:

sub chgfontname()
sheets(1).font.name="arial"
end sub

and for the rest of the sheets?
