我有一个旧的 VISIO 文件，上面有外部数据。数据的源文件不再存在。我试图将数据从 visio 复制并粘贴到 excel 中，但没有成功。

然后我尝试通过VBA访问数据，但我不明白我得到的结果：（行数是正确的，但数据有时好有时不好）

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

您知道如何将这些数据从 visio 获取到 excel 吗？

谢谢阿萨夫

更新：添加了源代码和输出：我重新检查并不知道数据来自哪里...... 在此处输入图像描述

这篇文章很旧，但我遇到了同样的问题并有解决方案。在您发布的代码中，您引用每个DataRecordSet并抓取第一行，而不是找到正确的代码并抓取所有行。

我们还必须避免使用i从 0 计数到ExternalData.Count; 行 ID 可以跳过数字，因此您必须使用正确的真实 ID DataRecordset。

以下代码并不完全漂亮，但它可以工作。请注意，linked布尔值并不是数据集的真正一部分；但是，它相当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，您可以使用分隔符将文件导入 Excel 。
