We have a spreadsheet into which we dump a large amount of data (averaging
around 55,000+ rows). We then use formulas to detect error in the data so
that we can go back into the original program and correct those errors. What
the code below does (my thanks to Rick Rothstein, MVP -VB) is hides all rows
which do not have errors leaving only the rows with errors (saves one from
having to scroll through more than 55,000 rows in search of errors).

My problem is that it takes to long to hide the rows (in excess of 5
minutes). Does anyone have any thoughts on how to speed up the process?

Sub HideRowIfZeroInG()
'
'
Application.ScreenUpdating = False

Dim R As Range
Dim LastRow As Long
With Worksheets("Negative Miles and Missing Perf")
LastRow = .Cells(Rows.Count, "J").End(xlUp).Row
If LastRow 65536 Then LastRow = 65536
For Each R In .Range("J3:J" & CStr(LastRow))
If R.Value = 0 And R.Value < "" Then R.EntireRow.Hidden = True
Next
End With

Application.ScreenUpdating = True

End Sub
