I have a sheet of almost 100000 rows & column A to Q I have a code that delete entire rows if column Q has blank cells.
I have tried this code on 4000 rows it is running in 3 minutes but when I take 100000 rows it just processing for hours.
I will be very great full if some help/guide me in speeding up this code.
The code is :
Sub DeleteBlank()
Application.ScreenUpdating = False
Application.Calculation = xlCalculationManual
Dim lo As ListObject
set lo = sheets("BOM 6061").ListObjects(1)
Sheets("BOM 6061").Activate
lo.AutoFilter.ShowAllData
lo.range.AutoFilter Field:=17, Criteria1:=""
Application.DisplayAlerts = False
Application.Calculation = xlCalculationAutomatic
lo.DataBodyRange.SpecialCells(xlCellsTypeVisible).Delete
Application.DisplayAlerts = True
lo.AutoFilter.ShowAllData
End Sub
Option Explicit
Sub DeleteBlankRows()
Const wsName As String = "BOM 6061"
Const tblIndex As Variant = 1
Const CriteriaColumnNumber As Long = 17
Const Criteria As String = ""
' Reference the table.
Dim wb As Workbook: Set wb = ThisWorkbook ' workbook containing this code
Dim ws As Worksheet: Set ws = wb.Worksheets(wsName)
Dim tbl As ListObject: Set tbl = ws.ListObjects(tblIndex)
Application.ScreenUpdating = False
Application.Calculation = xlCalculationManual
' Remove any filters.
If tbl.ShowAutoFilter Then
If tbl.AutoFilter.FilterMode Then tbl.AutoFilter.ShowAllData
Else
tbl.ShowAutoFilter = True
End If
' Add a helper column and write an ascending integer sequence to it.
Dim lc As ListColumn: Set lc = tbl.ListColumns.Add
lc.DataBodyRange.Value = _
ws.Evaluate("ROW(1:" & lc.DataBodyRange.Rows.Count & ")")
' Sort the criteria column ascending.
With tbl.Sort
.SortFields.Clear
.SortFields.Add2 tbl.ListColumns(CriteriaColumnNumber).Range, _
Order:=xlAscending
.Header = xlYes
.Apply
End With
' AutoFilter.
tbl.Range.AutoFilter Field:=CriteriaColumnNumber, Criteria1:=Criteria
' Reference the filtered (visible) range.
Dim svrg As Range
On Error Resume Next
Set svrg = tbl.DataBodyRange.SpecialCells(xlCellTypeVisible)
On Error GoTo 0
' Remove the filter.
tbl.AutoFilter.ShowAllData
' Delete the referenced filtered (visible) range.
If Not svrg Is Nothing Then svrg.Delete
' Sort the helper column ascending.
With tbl.Sort
.SortFields.Clear
.SortFields.Add2 lc.Range, Order:=xlAscending
.Header = xlYes
.Apply
.SortFields.Clear
End With
' Delete the helper column.
lc.Delete
Application.Calculation = xlCalculationAutomatic
Application.ScreenUpdating = True
' Inform.
MsgBox "Blanks deleted.", vbInformation
End Sub
