如何将visio外部数据导出为ex​​cel

Question

我有一个带有外部数据的旧VISIO文件。数据的源文件不再存在。 我试图从visio复制和粘贴数据，以取得成功。

然后我试图通过VBA访问数据，我不明白，结果我得到： （行的量是当期的，但该数据是时好时不）

Sub test() 
    Dim i, j As Integer 
    Dim r As Variant 
    Dim a() As Variant 
    Dim rowSTR As String 
    Dim vsoDataRecordset As Visio.DataRecordset 
    For i = 1 To Visio.ActiveDocument.DataRecordsets.Count 
     rowSTR = "" 
     a = Visio.ActiveDocument.DataRecordsets(i).GetRowData(1) 
     For j = 0 To UBound(a) - 1 
      rowSTR = rowSTR & vbTab & a(j) 
     Next j 
     Debug.Print i & ")" & rowSTR 
    Next i 
End Sub 

你知道如何从visio获取这些数据以达到excel吗？

这个职位是旧的，但我遇到了同样的问题，并有一个解决方案。在您的发布代码中，您引用了每个DataRecordSet并抓取第一行，而不是找到正确的并抓取所有行。

我们还必须避免使用i来计数从0到ExternalData.Count;行ID可以跳过数字，因此您必须使用正确的DataRecordset中的实际ID。

下面的代码不完全漂亮，但它的工作原理。请注意，linked布尔值不是真正的数据集的一部分;但它等同于外部数据窗口中的“链”图标。

这是为Visio 2013编写的，但我相信它也适用于其他版本。运行后，您可以使用%作为分隔符将文件导入Excel。
