python xlwings 复制工作表

其实xlwings在早期并没有提供复制工作表的相应函数,要实现复制工作表功能,需要调用excel的vba里面的相应方法worksheet.Copy。

在xlwings0.22版本以后,xlwings开始原生支持copy方法进行工作表复制,先说版本在0.22以下的旧办法:

首先看excel vba的帮助文档:

应用于 ChartChartsSheetsWorksheetWorksheets 对象的 Copy 方法。

将指定工作表复制到工作簿的另一位置。

expression.Copy(Before, After)

expression      必需。该表达式返回上面的对象之一。

Before      Variant 类型,可选。指定某工作表,复制的工作表将置于此工作表之前。如果已经指定了 After,则不能指定 Before

After      Variant 类型,可选。指定某工作表,复制的工作表将置于此工作表之后。如果已经指定了 Before,则不能指定 After

说明

如果既未指定 Before 参数也未指定 After 参数,则 Microsoft Excel 将新建一个工作簿,其中将包含复制的工作表。

本示例复制工作表 Sheet1,并将其放置在工作表 Sheet3 之后。

Worksheets("Sheet1").Copy After:=Worksheets("Sheet3")

那么在清楚了原理后,就可以在python里面码代码了

import xlwings as xw

wb = xw.Book('test.xls')
sheet = wb.sheets['Sheet1']

#将sheet1工作表复制到该工作簿的同一工作表的前面
sheet.api.Copy(Before=sheet.api)

#将sheet1工作表复制到新建工作簿中
sheet.api.Copy()

#将sheet1工作表复制到该工作簿的最后一个工作表后面
sheet2 = wb.sheets[-1]
sheet.api.Copy(After=sheet2.api)

#将sheet1工作表复制到另外一个工作簿dst.xls中最后个工作表之后
wb_dst=xw.Book("dst.xls")
ws_dst=wb_dst.sheets[-1]
sheet.api.Copy(After=ws_dst.api)

记住最后一个案例:

import xlwings as xw

wb = xw.Book(‘test.xls’)
sheet = wb.sheets[‘Sheet1’]

#将sheet1工作表复制到另外一个工作簿dst.xls中最后个工作表之后
wb_dst=xw.Book(“dst.xls”)
ws_dst=wb_dst.sheets[-1]
sheet.api.Copy(After=ws_dst.api)

最后说第二个方法:xlwings0.22以上版本的原生copy方法,贴上官方链接

v0.22.0 (Jan 29, 2021)

  • [Feature] While it’s always been possible to somehow create your own xlwings-based add-ins, this release adds a toolchain to make it a lot easier to create your own white-labeled add-in, see Custom Add-ins (GH1488).
  • [Enhancement] xw.view now formats the pandas DataFrames as Excel table and with the new xw.load function, you can easily load a DataFrame from your active workbook into a Jupyter notebook. See Jupyter Notebooks: Interact with Excel for a full tutorial (GH1487).
  • [Feature] New method mysheet.copy() (GH123).
  • PRO [Feature]: in addition to xw.create_report(), you can now also work within a workbook by using the new mysheet.render_template() method, see also xlwings Reports (GH1478).

Examples

# Create two books and add a value to the first sheet of the first book
first_book = xw.Book()
second_book = xw.Book()
first_book.sheets[0]['A1'].value = 'some value'

# Copy to same Book with the default location and name
first_book.sheets[0].copy()

# Copy to same Book with custom sheet name
