thanks!
thanks!
What is the 'special' character?
ASKER
any character not a-z or 0-9
Sub DeleteRows()
Dim lngLastRow As Long
Dim lngRow As Long
Application.ScreenUpdating = False
lngLastRow = Range("A1048576").End(xlUp).Row
For lngRow = lngLastRow To 1 Step -1
Select Case Asc(Left(Cells(lngRow, "A"), 1))
Case 48 To 57, 65 To 90, 97 To 122
' OK
' 0 to 9, A to Z, a to z
Case Else
Cells(lngRow, "A").EntireRow.Delete
End Select
Next
Application.ScreenUpdating = True
End Sub
If you only have single characters in column A then perhaps you could use this.
Dim I As Long
For I = Range("A" & Rows.Count).End(xlUp).Row To 2 Step -1
If Range("A" & I).Value Like "[!0-9A-Za-z]" Then
Rows(I).Delete
End If
Next I
340k rows of data for comparison? I would write a .qry (Microsoft query) to generate the output instead.
that could be faster than VBA codes to check row by row.

hi Martin, how long do you think it would take for that to run? still running 15 minutes later..
ASKER
looks like it eliminated 40k rows, but still many rows left to eliminate . see attached

Do you actually want to delete entire rows or do you just want to clear column A of special characters?
