开放式PYXL工作簿.保存函数可创建损坏且无法读取的Excel（.xlsx）fi

Question

我已经尝试过使用August William's solution来解决这个问题，但是也没用。我没有切换工作簿类型，即.xlsm到.xlsx，这似乎是一个单独的问题。我浏览了Openpyxl's Manual试图找到一个错误报告或错误修复，但没有结果。下面是我非常简单的代码。下面是python错误消息，它导致正在创建工作簿，但它已损坏并无法加载。感谢任何帮助。 -谢谢！！在

from openpyxl import Workbook


dashbrd = Workbook()
fp = dashbrd.active
fp.title = 'Sheet Name Goes Here'

fp['A1'] = 'Header'
fp['B1'] = '2nd Header'
fp['C1'] = '3rd Header'
fp['D1'] = '4th Header'
fp['E1'] = '5th Header'
fp['F1'] = 'You get the idea'
fp['G1'] = 'Another Header'
fp['H1'] = 'Blah blah blah'
fp['I1'] = 'Yadda yadda yadda'

dashbrd.save("S:\\folder1\\folder2\\folder3\\MyBook.xlsx")

Answer 1

我找不到一个好的参考，但我记得我偶然发现了相同的，解决方案是使用旧的格式（.xls，这是完全不同的格式）。似乎是openpyxl的一个普通问题，目前还没有解决。在

附加到.xlsx的工作方式（对我有用）：

from openpyxl import load_workbook
writer = pd.ExcelWriter(filename, engine='openpyxl')

try:
    # try to open an existing workbook
    writer.book = load_workbook(filename)

    # get the last row in the existing Excel sheet
    # if it was not specified explicitly
    if startrow is None and sheet_name in writer.book.sheetnames:
        startrow = writer.book[sheet_name].max_row

    # truncate sheet
    if truncate_sheet and sheet_name in writer.book.sheetnames:
        # index of [sheet_name] sheet
        idx = writer.book.sheetnames.index(sheet_name)
        # remove [sheet_name]
        writer.book.remove(writer.book.worksheets[idx])
        # create an empty sheet [sheet_name] using old index
        writer.book.create_sheet(sheet_name, idx)

    # copy existing sheets
    writer.sheets = {ws.title: ws for ws in writer.book.worksheets}
except FileNotFoundError:
    # file does not exist yet, we will create it
    pass

if startrow is None:
    startrow = 0

# write out the new sheet
df.to_excel(writer, sheet_name, startrow=startrow, **to_excel_kwargs)

# save the workbook
writer.save()

就像我上面说的，昨天我也遇到了同样的问题……我在这个环节找到了解决办法：

https://python-forum.io/Thread-Need-help-in-understanding-this-particular-Traceback-TypeError

关于这个错误： TypeError:获取了无效的类型输入值，应为字符串或元素

总之，解决方案是将openpyxl安装到另一个版本：

pip uninstall openpyxl
pip install openpyxl==3.0.1
