How to transfer data between worksheets in VBA by copying and pasting only the values that correspond to matching ID's?

edit

To transfer data between worksheets in VBA by copying and pasting only the values that correspond to matching ID's, you can follow these steps:

1. Identify the columns that contain the matching ID's in both the source and destination worksheets. For example, if you have a source worksheet named "Data" with columns A, B, and C, and a destination worksheet named "Results" with columns D, E, and F, and the ID's are in column A of both worksheets, then you can use column A as the matching ID.

2. Loop through each row of the source worksheet and compare the ID of the current row with the ID's in the destination worksheet to find a match.

3. If a match is found, copy the values from the columns that you want to transfer (e.g., columns B and C in the source worksheet) and paste them as values in the corresponding columns of the destination worksheet (e.g., columns E and F).

Here is a sample code:

Sub TransferData()
    Dim srcRow As Long, dstRow As Long, lastSrcRow As Long, lastDstRow As Long
    Dim srcID As Variant, dstID As Variant

    ' Set the starting row numbers and last row numbers for the source and destination worksheets
    srcRow = 2 ' start copying from row 2 (assuming row 1 contains header)
    dstRow = 2 ' start pasting to row 2 (assuming row 1 contains header)
    lastSrcRow = Worksheets("Data").Cells(Rows.Count, 1).End(xlUp).Row ' find the last row in column A of the source worksheet
    lastDstRow = Worksheets("Results").Cells(Rows.Count, 4).End(xlUp).Row ' find the last row in column D of the destination worksheet

    ' Loop through each row of the source worksheet
    For srcRow = 2 To lastSrcRow ' change 2 to the starting row number of your data
        srcID = Worksheets("Data").Cells(srcRow, 1).Value ' get the ID from column A of the source worksheet

        ' Loop through each row of the destination worksheet to find a match for the ID
        For dstRow = 2 To lastDstRow ' change 2 to the starting row number of your data
            dstID = Worksheets("Results").Cells(dstRow, 4).Value ' get the ID from column D of the destination worksheet

            ' If a match is found, copy the values from columns B and C of the source worksheet and paste as values in columns E and F of the destination worksheet
            If srcID = dstID Then
                Worksheets("Results").Cells(dstRow, 5).Value = Worksheets("Data").Cells(srcRow, 2).Value ' copy column B values from source and paste as values in column E of destination
                Worksheets("Results").Cells(dstRow, 6).Value = Worksheets("Data").Cells(srcRow, 3).Value ' copy column C values from source and paste as values in column F of destination
                Exit For ' exit the loop to avoid unnecessary comparisons
            End If
        Next dstRow
    Next srcRow
End Sub

In this example, the code assumes that:

• The source worksheet is named "Data", and the destination worksheet is named "Results".
• The ID's are in column A of both worksheets.
• The values to be transferred are in columns B and C of the source worksheet and columns E and F of the destination worksheet.
• Both worksheets ...
