Import data from a closed workbook (ADO)
Если вы хотите импортировать много данных из закрытой рабочей книги, вы можете сделать это с помощью ADO и макроса ниже. Если вы хотите извлечь данные из другой рабочей таблицы, отличной от первой рабочей таблицы в закрытой рабочей книге, вам нужно обратиться к определенному пользователем диапазону имен. Макрос ниже может использоваться следующим образом (в Excel 2000 или более поздней версии):
GetDataFromClosedWorkbook "C: \ FolderName \ WorkbookName.xls", "A1: B21", ActiveCell, False
GetDataFromClosedWorkbook "C: \ FolderName \ WorkbookName.xls", "MyDataRange", Range ("B3"), True
Sub GetDataFromClosedWorkbook(SourceFile As String, SourceRange As String, _
TargetRange As Range, IncludeFieldNames As Boolean)
' requires a reference to the Microsoft ActiveX Data Objects library
' if SourceRange is a range reference:
' this will return data from the first worksheet in SourceFile
' if SourceRange is a defined name reference:
' this will return data from any worksheet in SourceFile
' SourceRange must include the range headers
'
Dim dbConnection As ADODB.Connection, rs As ADODB.Recordset
Dim dbConnectionString As String
Dim TargetCell As Range, i As Integer
dbConnectionString = "DRIVER={Microsoft Excel Driver (*.xls)};" & _
"ReadOnly=1;DBQ=" & SourceFile
Set dbConnection = New ADODB.Connection
On Error GoTo InvalidInput
dbConnection.Open dbConnectionString ' open the database connection
Set rs = dbConnection.Execute("[" & SourceRange & "]")
Set TargetCell = TargetRange.Cells(1, 1)
If IncludeFieldNames Then
For i = 0 To rs.Fields.Count - 1
TargetCell.Offset(0, i).Formula = rs.Fields(i).Name
Next i
Set TargetCell = TargetCell.Offset(1, 0)
End If
TargetCell.CopyFromRecordset rs
rs.Close
dbConnection.Close ' close the database connection
Set TargetCell = Nothing
Set rs = Nothing
Set dbConnection = Nothing
On Error GoTo 0
Exit Sub
InvalidInput:
MsgBox "The source file or source range is invalid!", _
vbExclamation, "Get data from closed workbook"
End Sub
Другой метод, который не использует метод CopyFromRecordSet
С помощью макроса ниже вы можете выполнить импорт и лучше контролировать результаты, возвращаемые из RecordSet.
Sub TestReadDataFromWorkbook()
' fills data from a closed workbook in at the active cell
Dim tArray As Variant, r As Long, c As Long
tArray = ReadDataFromWorkbook("C:\FolderName\SourceWbName.xls", "A1:B21")
' without using the transpose function
For r = LBound(tArray, 2) To UBound(tArray, 2)
For c = LBound(tArray, 1) To UBound(tArray, 1)
ActiveCell.Offset(r, c).Formula = tArray(c, r)
Next c
Next r
' using the transpose function (has limitations)
' tArray = Application.WorksheetFunction.Transpose(tArray)
' For r = LBound(tArray, 1) To UBound(tArray, 1)
' For c = LBound(tArray, 2) To UBound(tArray, 2)
' ActiveCell.Offset(r - 1, c - 1).Formula = tArray(r, c)
' Next c
' Next r
End Sub
Private Function ReadDataFromWorkbook(SourceFile As String, SourceRange As String) As Variant
' requires a reference to the Microsoft ActiveX Data Objects library
' if SourceRange is a range reference:
' this function can only return data from the first worksheet in SourceFile
' if SourceRange is a defined name reference:
' this function can return data from any worksheet in SourceFile

' examples:
' varRecordSetData = ReadDataFromWorkbook("C:\FolderName\SourceWbName.xls", "A1:A21")
