This will work for blanks in column C:
[VBA]Option Explicit
Sub DeleteBlankColC()
Dim test As Boolean, x As Long, lastrow As Long, col As Long
Range("C1").Select
col = ActiveCell.Column
lastrow = Cells(65536, col).End(xlUp).Row
For x = lastrow To 1 Step -1
test = Cells(x, col).Text Like "[]"
If test = True Then Cells(x, col).EntireRow.Delete
Next
End Sub[/VBA]
