I have a worksheet filled with rows of data. My problem is that I wish to delete only those rows that are completely blank, say for esample I have a worksheet having data from A1:Z1 to A16636:Z16636, i.e. there are 16636 rows of data. It is possible that the first column in some of the rows may be blank, but I want only those rows to be deleted where all the cells in columns A to Z are completely blank. I found a code snippet (attached below) which deletes all rows not having data in column "A" but it does not solve m problem.

Please help!!
Sub DeleteBlankRows()

' Procedure : BlankRows

' Purpose   :

    Dim lRange As Long

    Dim lLoop As Long

   On Error GoTo DeleteBlankRows_Error
 

    lRange = InputBox("How many rows?", "Row Count", ActiveCell.SpecialCells(xlLastCell).Row)

    If lRange <> 0 Then

        ActiveCell.Offset(0, 0).Select

        Application.ScreenUpdating = False

        For lLoop = 1 To lRange

            If Trim(ActiveCell.Value) = "" Then

                Selection.EntireRow.Delete

                Else: ActiveCell.Offset(1, 0).Select

            End If

            Application.StatusBar = "Checking Row: " & lLoop & " of " & lRange

        Next lLoop

    End If

    Application.StatusBar = False

    Application.ScreenUpdating = True
 

   On Error GoTo 0
 

DeleteBlankRows_Exit:

   Exit Sub
 

DeleteBlankRows_Error:
 

    MsgBox "Error " & Err.Number & " (" & Err.Description & ") in procedure DeleteBlankRows of Module basDeleteBlankRows"

    Resume DeleteBlankRows_Exit
 

End Sub

Hello,

Perhaps you could insert a  column at the begining of the sheet, (i.e a new A column) and fill that column with this formula:

Formula in cell A1:
= B1 & C1 & D1 & E1 & ... & Z1

so this cell will have the concatenation of all values in a row, and then run your same code snippet, so if this first cell is blank, it will be because all the row is empty.

Hope it helps.
Regards

Dear MikeTob,

I am looking for VBA Code to handle the solution to this problem, as many a times, this needs to be handled from within code, as there is very little human intervention involved in the aforesaid spreadsheet. It could have worked as a perfectly valid solution in the scenario if the entire spreadsheet  was being managed in the human intervention mode, unfortunately, it is not, so it has to be a coded intervetion that is the solution I am looking for.

Ok, in that case you can use the following function to determine if a range is empty.

the range that you could pass as a parameter can be Range("A1:Z1"), for example, you could modify your code as this:

       For lLoop = 1 To lRange
            Selection.EntireRow.Select
            If RangeIsEmpty(Selection) Then
                Selection.EntireRow.Delete
            Else
                ActiveCell.Offset(1, 0).Select
            End If
            Application.StatusBar = "Checking Row: " & lLoop & " of " & lRange
        Next lLoop
 

Hope it helps
Function RangeIsEmpty(pRange As Range) As Boolean

  Dim lCell As Range

  Dim lEmpty As Boolean

    'Start

    lEmpty = True

  

    'scan all cells in the Range

    For Each lCell In pRange.Cells

       'Is not empty?

       If lCell.Value <> "" Then

          lEmpty = False

          Exit For

       End If

    Next

    

    'Return

    RangeIsEmpty = lEmpty

End Function
