我在看How do I call an Excel macro from Python using xlwings?,我知道它并不完全支持,但我想知道是否有办法做到这一点。

有些人喜欢:

from xlwings import Workbook, Application
wb = Workbook(...)
Application(wb).xl_app.Run("your_macro("%Args%")")

这可以通过做你的建议来完成。但请记住,此解决方案不是跨平台的(Win / Mac)。我在Windows上,所以下面必须调整到Mac上的appscript。 http://docs.xlwings.org/en/stable/missing_features.html

可以通过以下方式调用VBA脚本:

linked_wb.xl_workbook.Application.Run("vba_script", variable_to_pass)

实施例: 假设您有一个应在Excel中的数据验证列表中使用的字符串列表

的Python:

from xlwings import Workbook

linked_wb = Workbook.caller()

animals = ['cat', 'dog', 'snake', 'bird']
animal_list = ""
for animal in animals:
    animal_list += animal + "|"

linked_wb.xl_workbook.Application.Run("create_validation", animal_list)

Excel VBA:

Public Sub create_validation(validation_list)
    Dim validation_split() As String

    validation_split = Split(validation_list, "|")

    'The drop-down validation can only be created with 1-dimension array.
    'We get 1-D from the Split above
    With Sheet1.Range("A1").Validation
        .Delete
        .Add Type:=xlValidateList, AlertStyle:=xlValidAlertStop, _
        Operator:=xlBetween, Formula1:=Join(validation_split, ",")
    End With
End Sub
