Book¶
- class Book(fullname=None, update_links=None, read_only=None, format=None, password=None, write_res_password=None, ignore_read_only_recommended=None, origin=None, delimiter=None, editable=None, notify=None, converter=None, add_to_mru=None, local=None, corrupt_load=None, impl=None, json=None, mode=None, engine=None, **kwargs)¶
A book object is a member of the
bookscollection:>>> import xlwings as xw >>> xw.books[0] <Book [Book1]>
The easiest way to connect to a book is offered by
xw.Book: it looks for the book in all app instances and returns an error, should the same book be open in multiple instances. To connect to a book in the active app instance, usexw.booksand to refer to a specific app, use:>>> app = xw.App() # or xw.apps[10559] (get the PIDs via xw.apps.keys()) >>> app.books['Book1']
xw.Book
xw.books
New book
xw.Book()xw.books.add()Unsaved book
xw.Book('Book1')xw.books['Book1']Book by (full)name
xw.Book(r'C:/path/to/file.xlsx')xw.books.open(r'C:/path/to/file.xlsx')- パラメータ:

update_links (bool | None) -- 引数が省略された場合、リンクのアップデートについてのプロンプトが現れます。
read_only (bool | None) -- Trueにすればワークブックを読み取り専用で開きます

RunPython. Pack it into the function being called from Excel, e.g.:import xlwings as xw def my_macro(): wb = xw.Book.caller() wb.sheets[0].range('A1').value = 1
To be able to easily invoke such code from Python for debugging, use
xw.Book.set_mock_caller().Added in version 0.3.0.

- save(path=None, password=None)¶
Saves the Workbook. If a path is provided, this works like SaveAs() in Excel. If no path is specified and if the file hasn't been saved previously, it's saved in the current working directory with the current filename. Existing files are overwritten without prompting.
