Hi there,

I have a weird request. I have a Destination File named Scheduler with the following columns A and B:
1635164686654.png

Then I have a Source File called MOSTATUS, with the following columns A and B:
1635164743329.png

Both MOSTATUS and Scheduler are different workbooks.

What I would like to achieve is, when the user hits the "Import data" button, the VBA script would compare Columns A and Columns B of the Destination and the Source File, delete the duplicate rows in the Source File, delete all the data in the Destination File, and import the remaining data in the Source File into the Destination File.

I found these links, but I'm not sure how any of them could be of use to me:

Any help would be greatly appreciated. Thank you for your assistance and time.

What is the fastest way to copy a formula?
If A2:A50000 contain data. Enter a formula in B2. Select B2. Double-click the Fill Handle and Excel will shoot the formula down to B50000.

To clarify for example MO00003831-AL in the Destination File should be compared to possible matches of MO00003831-AL in the Source File. If found in the Source File for the same match, that entire row should be deleted.

To help anyone who may need it in the future, this is what I ended up doing:

VBA Code:
Private Sub CommandButton1_Click()
  Dim sh1 As Worksheet, sh2 As Worksheet, dic As Object
  Dim r1 As Range, r2 As Range, a As Variant, b As Variant
  Dim i As Long, lr1 As Long, lr2 As Long
  Dim wb As Workbook
  Dim fPath
  
  fPath = Application.GetOpenFilename(FileFilter:="Excel Files (*.XLSX), *.XLSX", Title:="Select File To Be Opened")
  Set wb = Workbooks.Open(fPath)
  
  Set sh1 = Workbooks("p1.xlsm").Worksheets("Sheet1")
  Set sh2 = wb.Worksheets("Sheet1")
  Set dic = CreateObject("Scripting.Dictionary")
  
  dic.CompareMode = vbTextCompare
  lr1 = sh1.Range("A" & Rows.Count).End(xlUp).Row
  lr2 = sh2.Range("A" & Rows.Count).End(xlUp).Row
  a = sh1.Range("A1:B" & lr1).Value2
  b = sh2.Range("A1:B" & lr2).Value2
  Set r1 = sh1.Range("A" & lr1 + 1)
  Set r2 = sh2.Range("A" & lr2 + 1)
  
  For i = 1 To UBound(a, 1)
    dic(a(i, 1) & a(i, 2)) = i
  Next
  For i = 1 To UBound(b, 1)
    If dic.exists(b(i, 1) & b(i, 2)) Then
      Set r2 = Union(r2, sh2.Range("A" & i))
    End If
  Next
  r2.EntireRow.Delete
  
  
End Sub
