I have 2 workbooks total.

Workbook A, which has around 16000 rows + of data. Then Workbook B, which is the one I'm working in has an active directory list.

I have 3 rows of data. Column A, B, C, which should or is listed within both workbooks. I'm using an input box to find the date (where the forth condition comes into play).
Example:
Workbook A & B
Column A: DIS
Column B: ERT
Column C: 1100
Column D: 5/1/2023 / Inputbox answer (dimmed as Ans)

The information is in the same location for both workbooks and I made this macro, so it'll tell me if it can find it within Workbook A. If its unable to, then it'll post a note in column E saying "Unable to locate", so I know to go in and add it before I export my data to workbook A.

The main issue with this code is it is increditly slow. Does anyone here have any suggestions on how to improve its speed? I have 500 rows on Workbook B to check, so it'll take around 20-30 minutes to process.

VBA Code:
Private Sub Lot_Blocks_Click()
    Dim lastRow As Long                                     
    Dim aws As Workbook                                         
    Dim ws As Worksheet                                       
    Dim i As Integer
    Dim Ans As String
    Dim msBldr As String
    Dim msTract As String
    Dim msLot As String
    Dim msDate As String
    Dim asBldr As String
    Dim asTract As String
    Dim asLot As String
    Dim asDate As String
    Dim c As Range
    Dim FoundLotBlock As Long
    
    Ans = InputBox("Please input the date." & vbCrLf & _
        "Example: 12/1/2017")
    If Ans = "" Then
        Exit Sub
    Else
        lastRow = Dirr.Range("A:A").Cells.SpecialCells(xlCellTypeConstants).Count
        Set ws = ThisWorkbook.Sheets("Directory")
        Set aws = Workbooks.Open(PathSetup.Range("C2"))

        For i = 1 To lastRow
            FoundLotBlock = 0
            For Each c In Columns("A").Cells
                msBldr = ws.Cells(i, 1).Value                              
                msTract = ws.Cells(i, 2).Value                              
                msLot = ws.Cells(i, 3).Value                               
                msDate = Ans                                            
                asBldr = aws.Sheets("CA Wip Master").Cells(c.Row, 1).Value  
                asTract = aws.Sheets("CA Wip Master").Cells(c.Row, 2).Value 
                asLot = aws.Sheets("CA Wip Master").Cells(c.Row, 3).Value  
                asDate = aws.Sheets("CA Wip Master").Cells(c.Row, 7).Value  
                If asBldr = msBldr And _
                    asTract = msTract And _
                    asLot = msLot And _
                    asDate = msDate Then
                        FoundLotBlock = 1
                End If
                If FoundBlock = 1 Then

                End If
            Next c

            Else

What is the shortcut key for Format Selection?
Ctrl+1 (the number one) will open the Format dialog for whatever is selected.
One of the main reasons that Vba is slow is the time taken to access the worksheet from VBa is a relatively long time.
To speed up vba the easiest way is to minimise the number of accesses to the worksheet. What is interesting is that the time taken to access a single cell on the worksheet in vba is almost identical as the time taken to access a large range if it is done in one action.

So instead of writing a loop which loops down a range copying one row at a time which will take along time if you have got 50000 rows it is much quicker to load the 50000 lines into a variant array ( one worksheet access), then copy the lines to a variant array and then write the array back to the worksheet, ( one worksheet access for each search that you are doing),

I have a simple rule for fast VBA: NEVER ACCESS THE WORKSHEET IN A LOOP.
In your code you have a DOUBLE loop so it is going to be very very slow. I have modified your code to load the data inot two varaint arrrays at the start and then do the loops without accessing the worksheets this should be over 1000 times faster, .
Anotehr thing to be wary of when writing loops is to avoid putting statement into the loop that doesn't need to be in the loop You can see that I have moved a number of your statements out of the loops because the variable doesn't change inside the innermost loop or in the case of ANS both loops.

you have got two commas which is probably the problem, sorry my mistake( I said it was untested0
ditto on this line:
VBA Code:
.Range(.Cells(1, 1).Cells(wslr, , 5)) = wsarr         ' write array back to workshseet
check them all, I did a bit of copy and paste

asDate = awsarr(j, 7) '...where does the 7 come into play?
the 7 comes into play because this line is exactly equivalent to this line in your orginal code:
VBA Code:
 asDate = aws.Sheets("CA Wip Master").Cells(c.Row, 7).Value
I actually did the change by using a global change of "aws.Sheets("CA Wip Master").Cells(c.Row" to"awsarr(j"
very easy to do,
and then ".Value" to ""
as you can see using variant arrays can be faster to write as well as being faster to run!!

Another modification which you should consider. is the GOTO statement is generally frowned on as being likely to end up making code very difficult to maintain. you are using it just to exit a loop:
VBA Code:
                       FoundLotBlock = 1
                End If
                If FoundBlock = 1 Then
                    GoTo ProceedForward
                End If
there is a very useful bit code you can use instead of this;
VBA Code:
  Exit For
 End  If
this is exactly equivalent to the code I posted above

May not be of any help but you may also be able to do this with a IF/COUNTIFS formula:
Excel Formula:
=IF(COUNTIFS([Book2]Sheet1!$A2:$A8,A2:A20,[Book2]Sheet1!$B2:$B8,B2:B20,[Book2]Sheet1!$C2:$C8,C2:C20)<1,"ADD","")

Solution
May not be of any help but you may also be able to do this with a IF/COUNTIFS formula:
Excel Formula:
=IF(COUNTIFS([Book2]Sheet1!$A2:$A8,A2:A20,[Book2]Sheet1!$B2:$B8,B2:B20,[Book2]Sheet1!$C2:$C8,C2:C20)<1,"ADD","")
surprisingly, i used this idea to make the macro run a lot smoother. I could not figure out the directory for the life of me. Its tacky, but works a lot faster.
VBA Code:
Private Sub Lot_Blocks_Click()
    Dim i As Long
    Dim aws As Workbook
    Dim AccRow As Long
    Dim lastRow As Long
    Dim FileName As String
    Dim cFormula As String
    
    Set aws = Workbooks.Open(PathSetup.Range("C2"))
    AccRow = aws.Sheets("CA Wip Master").Range("A:A").Cells(Rows.Count, 1).End(xlUp).Row
    lastRow = Dirr.Range("A:A").Cells.SpecialCells(xlCellTypeConstants).Count
    FileName = PathSetup.Range("C3").Value
    
    If Labor_From.Value > 0 Then
        '...format column for inputs
        Dirr.Columns("E:E").ColumnWidth = 27.86
        '...input date
        Dirr.Range("D1" & ":" & "D" & lastRow).Value = Labor_From.Value
        '...insert checklist
        For i = 1 To lastRow
            cFormula = "=IF(COUNTIFS('[" + FileName & "]CA Wip Master'!$A$1:$A$" & AccRow & ",A" & i & _
                ",'[" + FileName & "]CA Wip Master'!$B$1:$B$" & AccRow & ",B" & i & _
                ",'[" + FileName & "]CA Wip Master'!$C$1:$C$" & AccRow & ",C" & i & _
                ",'[" + FileName & "]CA Wip Master'!$G$1:$G$" & AccRow & ",D" & i & _
                ")<1,""Action Required."","""")"
            If Dirr.Cells(i, 5).Value = "" Then
                Dirr.Cells(i, 5).Value = cFormula
            End If
        Next i
        
        '...Clear out Formulas
        Dirr.Columns("E:E").Copy
        Dirr.Columns("E:E").PasteSpecial Paste:=xlPasteValues
        Dirr.Activate
            Range("E1").Select
        Application.CutCopyMode = False
        MsgBox "Check Complete!", vbOKOnly
    Else
        MsgBox "Enter a date first into the Labor"
    End If
End Sub

asDate = awsarr(j, 7) '...where does the 7 come into play?

the 7 comes into play because this line is exactly equivalent to this line in your orginal code:
VBA Code:
 asDate = aws.Sheets("CA Wip Master").Cells(c.Row, 7).Value
I actually did the change by using a global change of "aws.Sheets("CA Wip Master").Cells(c.Row" to"awsarr(j"
very easy to do,
and then ".Value" to ""
as you can see using variant arrays can be faster to write as well as being faster to run!!
Appreciate all the information, but I couldn't figure out how to get the directory to work. I had to use another method, but thank you for everything!
