Hmm my code seems to be playing up, any ideas...

So basically the code below is to help me automate a repetitive task.

However for some reason the only part not working as it should is the function where it changes K column from TRUE/FALSE to 1/0 accordingly...any ideas.. Thanks

Sub AutomateReporting()
    Dim ws As Worksheet
    Dim LastRowA As Long, LastRowK As Long, LastRowF As Long
    Dim rng As Range, cell As Range
    Dim destSheet As Worksheet
    Dim sheetOrder() As String
    Dim i As Long, j As Long
    
    ' Define the worksheet to work with
    Set ws = ThisWorkbook.Sheets("sheet1") ' Change "sheet1" to your sheet's name
    
    ' Turn off screen updating to improve performance
    Application.ScreenUpdating = False
    
    ' Clear any existing filters
    ws.AutoFilterMode = False
    
    ' Find the last row with data in column A, K, and F
    LastRowA = ws.Cells(ws.Rows.Count, 1).End(xlUp).Row
    LastRowK = ws.Cells(ws.Rows.Count, 11).End(xlUp).Row
    LastRowF = ws.Cells(ws.Rows.Count, 6).End(xlUp).Row
    
    ' Filter column A to find entries starting with 'AA'
    ws.Range("A2:A" & LastRowA).AutoFilter Field:=1, Criteria1:="AA*", Operator:=xlFilterValues
    
    ' Store the range of visible rows with data excluding the header
    On Error Resume Next ' In case no visible cells to delete
    Set rng = ws.Range("A2:A" & LastRowA).SpecialCells(xlCellTypeVisible)
    On Error GoTo 0
    
    ' Delete visible rows containing 'AA' in column A
    If Not rng Is Nothing Then
        rng.EntireRow.Delete
    End If
    
    ' Find the new last row with data in column A after deleting filtered rows
    LastRowA = ws.Cells(ws.Rows.Count, 1).End(xlUp).Row
    
    ' Filter column K to find 'New'
    ws.AutoFilterMode = False
    ws.Range("K1:K" & LastRowK).AutoFilter Field:=1, Criteria1:="New"
    
    ' Find the last row with data in column K after filtering for 'New'
    LastRowK = ws.Cells(ws.Rows.Count, 11).End(xlUp).Row
    
    ' Convert TRUE to 1 and FALSE to 0 in column K
    For Each cell In ws.Range("K2:K" & LastRowK)
        If cell.Value = "TRUE" Then
            cell.Value = "1"
        ElseIf cell.Value = "FALSE" Then
            cell.Value = "0"
        End If
    Next cell
    
    ' Filter column F to find the unique values
    Dim uniqueValues() As Variant
    uniqueValues = GetUniqueValues(ws.Range("F2:F" & LastRowF))
    
    ' Define the order of sheets
    ReDim sheetOrder(1 To 8) As String
    sheetOrder(1) = "New"

One in quotes (i.e., "1") is a character, not a number. "TRUE" in quotes is a character string typed in manually, not the Boolean result of a formula. I don't know which you are dealing with since there is no sample file

   For Each cell In ws.Range("K2:K" & LastRowK)
             .Value = IIF(.Value=TRUE,1,0)
   Next cell
