how to automatically transfer data from one excel worksheet to another with vba and macros

Question

Accepted Answer

Transferring data between Excel worksheets with VBA involves writing a macro that reads values from a source sheet and writes them to a destination sheet, either as a one-time run or automatically when something changes. Here's a practical rundown of the common approaches.

**Basic manual-trigger macro**

```vba
Sub TransferData()
    Dim wsSource As Worksheet, wsDest As Worksheet
    Dim lastRow As Long

Set wsSource = ThisWorkbook.Sheets("Sheet1")
    Set wsDest = ThisWorkbook.Sheets("Sheet2")

lastRow = wsSource.Cells(wsSource.Rows.Count, "A").End(xlUp).Row

wsSource.Range("A1:D" & lastRow).Copy _
        Destination:=wsDest.Range("A" & wsDest.Cells(wsDest.Rows.Count, "A").End(xlUp).Row + 1)
End Sub
```
This copies a range dynamically (based on the last used row) and pastes it into the next empty row on the destination sheet, avoiding overwritten data.

**Copying only specific cells or with conditions**

Instead of `.Copy`, loop through rows and use an `If` statement to filter which rows qualify (e.g., only rows where a status column equals "Complete"), assigning values cell-by-cell with `wsDest.Cells(r, c).Value = wsSource.Cells(r, c).Value`. This avoids clipboard issues and formatting problems.

**Making it automatic**

To trigger the transfer without manually running the macro:
- **Worksheet_Change event**: Place code in the source sheet's code module using `Private Sub Worksheet_Change(ByVal Target As Range)` so it fires whenever a cell is edited.
- **Workb
