I need VBA to delete lines related to date

I receive a daily excel table which has a variable number of lines.n be anything from 5 to 10000 lines.
Lines 1 to 11 are statis (always contain the same headers etc).
Line 12 onwards contain the data.
There are a list of dates in column U
I would like VBA to delete any lines from line 5 onwards whose date in col U is not tomorrow.

Bing search "Excel VBA delete rows".
Review https://analysistabs.com/vba/delete-...-example-code/

maybe try this version

Code:

---

Sub sbDelete_Rows _Date()
Dim lRow As Long
Dim iCntr As Long
lRow = 10000
For iCntr = lRow To 12 Step -1
    If Cells(iCntr, 21) = Today() Then
        Rows(iCntr).Delete
    End If
Next
End Sub

If you have a lot of rows, a more complicated approach would offer performance improvements

Code:

---

Option Explicit


Sub DeleteSomeRows()
    Dim r1 As Range, r2 As Range, r As Range, r12 As Range
    Dim tomm As Date
   
    Application.ScreenUpdating = False
   
    With ActiveSheet
        Set r1 = .Cells(5, 21)
        Set r2 = .Cells(.Rows.Count, 21).End(xlUp)
        Set r12 = Range(r1, r2)
    End With
   
    tomm = Date + 1
   
    For Each r In r12.Cells
        With r
            If IsDate(.Value) Then
                If Int(.Value) <> tomm Then .Value = True
            End If
        End With
    Next
   
    On Error Resume Next
    r12.SpecialCells(xlCellTypeConstants, xlLogical).EntireRow.Delete
    On Error GoTo 0


    Application.ScreenUpdating = True


End Sub
