我想听听专家提供的有关如何将访问数据库导出到csv的选项，而无需打开数据库并逐个选择表。我有148个表，我想将数据转换为csv。这样做的最佳方式是什么？

我不认为你可以做到这一点，至少不打开Access，这样你就可以与之互动。无论如何，只需在From上创建一个按钮，或者以其他方式触发Macro，然后运行下面的脚本。
Option Compare Database
Private Sub Command0_Click()
Dim db As DAO.Database
Dim tdf As DAO.TableDef
Dim rst As DAO.Recordset
Dim oXL As Object
Dim oWrkBk As Object
Set db = CurrentDb
'Create instance of Excel.
Set oXL = CreateXL
For Each tdf In db.TableDefs
If Left(tdf.Name, 4) <> "MSys" Then
'Create workbook with single sheet.
Set oWrkBk = oXL.Workbooks.Add(-4167) 'xlWBATWorksheet
'Open the table recordset.
Set rst = tdf.OpenRecordset
'In the immediate window display table name and TRUE/FALSE if exported successfully.
Debug.Print tdf.Name & " - " & QueryExportToXL(oWrkBk.Worksheets(1), , rst, tdf.Name)
'Save and close the workbook.
oWrkBk.SaveAs "C:\your_path\" & tdf.Name & ".xlsx"
oWrkBk.Close
End If
Next tdf
End Sub
