Python 3.x openpyxl-覆盖数据表并保留数据透视表
我已经看到了这个问题的一些答案,但没有一个是有效的。 例如: 医生们似乎什么都不说: 我尝试用Python 3.x openpyxl-覆盖数据表并保留数据透视表,python-3.x,openpyxl,Python 3.x,Openpyxl,我已经看到了这个问题的一些答案,但没有一个是有效的。 例如: 医生们似乎什么都不说: 我尝试用xls.reader.excel.load\u工作簿替换xls.load\u工作簿,但没有任何改变 我的当前代码覆盖了数据表中的数据,但终止了另一个数据表中的透视表功能(该数据表仍然存在,但仅包含值)。你知道如何保持数据透视表吗 import pandas as pd import openpyxl as xls from shutil import copyfile template_file =
xls.reader.excel.load\u工作簿
替换xls.load\u工作簿
,但没有任何改变
我的当前代码覆盖了数据表中的数据,但终止了另一个数据表中的透视表功能(该数据表仍然存在,但仅包含值)。你知道如何保持数据透视表吗
import pandas as pd
import openpyxl as xls
from shutil import copyfile
template_file = 'openpy_test.xlsx'
output_file = 'openpy_output.xlsx'
copyfile(template_file, output_file)
book = xls.load_workbook(output_file,guess_types=False,data_only=False)
writer = pd.ExcelWriter(output_file,engine='openpyxl')
writer.book = book
writer.sheets = dict((ws.title, ws) for ws in book.worksheets)
df.to_excel(writer,sheet_name='data',index=False,encoding='utf8')
writer.save()
我还尝试了book.save('dummycopy.xlsx')
,它也使用非功能透视表进行保存。因此,我确信问题与load_工作簿函数有关
软件包版本:
openpyxl 2.4.10 py36_0
熊猫0.20.3 py36hce827b7_2我认为openpyxl目前不支持excel数据透视表。我不得不改用win32com库 下面是我编写的包装器模块,用于处理透视表的特定内容;它基本上是将VBA翻译成python(记录宏并读取VBA,这很有意义)。希望能有帮助。这仍然是一项正在进行的工作,但应该足以让您与之合作

您需要openpyxl 2.5。感谢您提供的大量函数集。我相信它会派上用场的
