保存工作簿时出现 OpenPyXL 错误：已存在具有相同名称和范围的 DefinedName

Question

我想在 Python 中使用 OpenPyXL 编辑 Excel-XLSX 文件中的一个单元格，然后将此更改后的文件保存到具有其他名称的 xlsx 中。但我收到以下错误：回溯（最近调用最后）：

 File "E:\ExcelPythonTest\workspace\ExcelTest\ExcelTest.py", line 14, in <module>
    book.save(path2)
  File "C:\Python27\lib\site-packages\openpyxl-2.4.0b1-py2.7.egg\openpyxl\workbook\workbook.py", line 294, in save
    save_workbook(self, filename)
  File "C:\Python27\lib\site-packages\openpyxl-2.4.0b1-py2.7.egg\openpyxl\writer\excel.py", line 270, in save_workbook
    writer.save(filename)
  File "C:\Python27\lib\site-packages\openpyxl-2.4.0b1-py2.7.egg\openpyxl\writer\excel.py", line 251, in save
    self.write_data()
  File "C:\Python27\lib\site-packages\openpyxl-2.4.0b1-py2.7.egg\openpyxl\writer\excel.py", line 94, in write_data
    archive.writestr(ARC_WORKBOOK, write_workbook(self.workbook))
  File "C:\Python27\lib\site-packages\openpyxl-2.4.0b1-py2.7.egg\openpyxl\writer\workbook.py", line 121, in write_workbook
    defined_names.append(name)
  File "C:\Python27\lib\site-packages\openpyxl-2.4.0b1-py2.7.egg\openpyxl\workbook\defined_name.py", line 191, in append
    raise ValueError("""DefinedName with the same name and scope already exists""")
ValueError: DefinedName with the same name and scope already exists

我的代码：

import os
import openpyxl

# Change this to suit
path = r'E:\ExcelPythonTest\example.xlsx'
path2 = r'E:\ExcelPythonTest\examle_UHAHAHAHAHHA.xlsx'

book = openpyxl.load_workbook( path )
sheet = book.get_sheet_by_name('Dictionary')
print sheet['G8'].value
sheet['G8'] =  3.18
print sheet['G8'].value

book.save(path2)

谁能帮帮我？

P.S：我试图用 C 和 c-library libxl 中的代码编辑相同的 .xlsx。所以我认为 xlsx 文件没有问题。

我在没有对 xlsx 进行任何编辑的情况下尝试了以下代码：

import os
import openpyxl

# Change this to suit
path = r'E:\ExcelPythonTest\Dt_RECORD_SHPS_RM_ROStruct.xlsx'
path2 = r'E:\ExcelPythonTest\Dt_RECORD_SHPS_RM_ROStruct_UHAHAHAHAHHA.xlsx'

book = openpyxl.load_workbook( path )

book.save(path2)

但是还是出现了同样的错误

Answer 1

我在工作中遇到了同样的问题，直到找到解决方案。您只需要在现有代码中添加一行。我不完全知道 definedName 对象有什么用，但生成的文件没有损坏（与没有该行不同）并且似乎没有因清除 definedNames 列表而导致的任何视觉差异。

import os
import openpyxl

# Change this to suit
path = r'E:\ExcelPythonTest\example.xlsx'
path2 = r'E:\ExcelPythonTest\examle_UHAHAHAHAHHA.xlsx'

book = openpyxl.load_workbook( path )
sheet = book.get_sheet_by_name('Dictionary')
print sheet['G8'].value
sheet['G8'] =  3.18
print sheet['G8'].value

# This fixes it   
book.defined_names.definedName = []

book.save(path2)
