Delete empty rows using VBA - MS Excel - vba

Question

I am looking to see if there is a more efficient way to achieve the result below, so it can be extended if needed.
I'm using this to clean up large spreadsheets that have the rows C-Z blank. I imagine there should be a way to clean it up so that it doesn't have to double in size if I need to clean up a spreadsheet with data from C to AZ.
It's been a while since I used VBA, I found the code below online. (counting ROW B as the spreadsheet in question had an empty ROW A)
Sub delem()
Dim lr As Long, r As Long
lr = Cells(Rows.Count, "B").End(xlUp).Row
For r = lr To 1 Step -1
If Range("C" & r).Value = "" And Range("D" & r).Value = "" And Range("E" & r).Value = "" And Range("F" & r).Value = "" And Range("G" & r).Value = "" And Range("H" & r).Value = "" And Range("I" & r).Value = "" And Range("J" & r).Value = "" And Range("K" & r).Value = "" And Range("L" & r).Value = "" And Range("M" & r).Value = "" And Range("N" & r).Value = "" And Range("O" & r).Value = "" And Range("P" & r).Value = "" And Range("Q" & r).Value = "" And Range("R" & r).Value = "" And Range("S" & r).Value = "" And Range("T" & r).Value = "" And Range("U" & r).Value = "" And Range("V" & r).Value = "" And Range("W" & r).Value = "" And Range("X" & r).Value = "" And Range("Y" & r).Value = "" And Range("Z" & r).Value = "" Then Rows(r).Delete
Next r
End Sub
Thanks!

Answer 1

Just add an inner loop to go through the columns you care about. This will actually run much faster, as VBA doesn't short-circuit the If statement (all of the conditionals are evaluated). But with the loop, you can exit early if you find a value anywhere:
Sub delem()
Dim last As Long
Dim current As Long
Dim col As Long
Dim retain As Boolean
last = Cells(Rows.Count, "B").End(xlUp).Row
For current = last To 1 Step -1
retain = False
For col = 3 To 26
If Cells(current, col).Value <> vbNullString Then
retain = True
Exit For
End If
Next col
If Not retain Then Rows(current).Delete
Next current
End Sub

The Excel worksheet function COUNTA is a clean way to test if a range is empty.
Sub delem()
Dim lr As Long, r As Long
lr = Cells(Rows.Count, "B").End(xlUp).Row
For r = lr To 1 Step -1
'This function Counts the number of cells that are not empty
If WorksheetFunction.CountA(Range(Cells(r, 3), Cells(r, 26)) = 0 Then
Rows(r).Delete
End If
Next r
End Sub
