class App(visible=None, spec=None, add_book=True, impl=None)

An app corresponds to an Excel instance and should normally be used as context manager to make sure that everything is properly cleaned up again and to prevent zombie processes. New Excel instances can be fired up like so:

import xlwings as xw

with xw.App() as app:

appオブジェクトは apps コレクションのメンバーです:

>>> xw.apps
Apps([<Excel App 1668>, <Excel App 1644>])
>>> xw.apps[1668]  # get the available PIDs via xw.apps.keys()
<Excel App 1668>
<Excel App 1668>


visiblebool, default None


specstr, default None

Macのみ、Excelアプリケーションへのフルパスを指定します。例えば、/Applications/Microsoft Office 2011/Microsoft Excel/Applications/Microsoft Excel

Windowsでは、xlwingsと連携するExcelのバージョンを変更したい場合、コントロールパネル > プログラムと機能 からデフォルトで使いたいオフィスのバージョンに 変更 します。


Macでは、xlwingsを使えば複数のExcelインスタンスを実行できますが、複数のExcelインスタンスの実行はMac版Excelでは公式にはサポートされていません: Windowsとは異なり、既に他のインスタンスで開かれているファイルをを開こうとする時に、Excelは読み取り専用で開くかどうかを聞きません。したがって、同じファイルが異なるインスタンスから上書きされていないかどうかを気を付ける必要があります。


Exel appをアクティブにします。


steal_focusbool, default False


Added in version 0.9.0.

alert(prompt, title=None, buttons='ok', mode=None, callback=None)

This corresponds to MsgBox in VBA, shows an alert/message box and returns the value of the pressed button. For xlwings Server, instead of returning a value, the function accepts the name of a callback to which it will supply the value of the pressed button.


promptstr, default None

The message to be displayed.

titlestr, default None

The title of the alert.

buttonsstr, default "ok"

Can be either "ok", "ok_cancel", "yes_no", or "yes_no_cancel".

modestr, default None

Can be "info" or "critical". Not supported by Google Sheets.

callbackstr, default None

Only used by xlwings Server: you can provide the name of a function that will be called with the value of the pressed button as argument. The function has to exist on the client side, i.e., in VBA or JavaScript.


button_value: str or None

Returns None when used with xlwings Server, otherwise the value of the pressed button in lowercase: "ok", "cancel", "yes", "no".

特定のワークブックではない、アドイン等に含まれるExcel VBAのSubやFunctionを実行します。


nameName of Sub or Function with or without module name,

e.g., 'Module1.MyMacro' or 'MyMacro'


Function MySum(x, y)
    MySum = x + y
End Function


>>> import xlwings as xw
>>> app = xw.App()
>>> my_sum = app.macro('MySum')
>>> my_sum(1, 2)

Types are supported too:

Function MySum(x as integer, y as integer)
    MySum = x + y
End Function
>>> import xlwings as xw
>>> app = xw.App()
>>> my_sum = app.macro('MySum')
>>> my_sum(1, 2)

However typed arrays are not supported. So the following won't work

Function MySum(arr() as integer)
    ' code here
End Function

property path

Context manager that allows you to easily change the app's properties temporarily. Once the code leaves the with block, the properties are changed back to their previous state. Note: Must be used as context manager or else will have no effect. Also, you can only use app properties that you can both read and write.

import xlwings as xw
app = App()

# Sets app.display_alerts = False
    # do stuff

# Sets app.calculation = 'manual' and app.enable_events = True
with'manual', enable_events=True):
    # do stuff

# Makes sure the status bar is reset even if an error happens in the with block
    # do stuff
