Question

我试图使用openpyxl模块打开XLSX文件。以下是我的剧本： -

from openpyxl import load_workbook

print "Going to execute the script"
workbook = load_workbook("FileName.xlsx")
worksheet = workbook.get_sheet_by_name("Sheet01")
worksheet['B8'] = "Customer07"
workbook.save("FileName.xlsx")
print "End of script execution"

当我执行此脚本时，我收到以下错误： -

/usr/lib/python2.6/site-packages/openpyxl-2.2.0-py2.6.egg/openpyxl/xml/__init__.py:15: UserWarning: The installed version of lxml is too old to be used with openpyxl
  warnings.warn("The installed version of lxml is too old to be used with openpyxl")

    t.append('&%d' % self.font_size)
TypeError: %d format: a number is required, not str

此后，当我打开＆＃34; FileName.xlsx＆＃34;时，弹出框中显示消息＆＃34; Excel在＆＃39; FileName.xlsx＆＃39;中找到了不可读的评论。你想要恢复这个工作簿的内容吗？如果您信任此工作簿的来源，请单击是＆＃34; 。无论我点击什么按钮，工作簿都是空的。

如果我在脚本中评论以下行，

workbook.save("FileName.xlsx")

脚本运行时没有任何错误，但修改不保存在工作簿中。请帮帮我。

我昨晚遇到了同样的问题，我认为我的Excel文件没有标题，但实际上它确实有一个页眉和页脚（当你按“打印预览”时可能会看到）< / p>

无论如何，这是我的hacky修复：

我注释掉了这行代码并添加了pass行

"<path-to-library>/openpyxl/worksheet/header_footer.py", line 90, in get
Line 89-91 below

if self.font_size:
    # t.append('&%d' % self.font_size) # commented out this line
    pass # added this line "pass"

此“修复”只会影响页眉和页脚的font_size（如果你问我，这不是特别大的交易）。但是您可能会发现您希望将这些页眉和页脚存储到变量中，以便您可以在程序的未来以其他方式使用它们。

如果是这种情况，我在下面提供了一些代码，将这些页眉和页脚提取到相应的词典中（如果存在的话）。

注意：这可能也有助于确定您的文档是否有页眉和页脚。

wb.save(<path/to/file>)之后：

header_dict = {}
if ws.header_footer.hasHeader():
    header_dict['center'] = ws.header_footer.center_header.text
    header_dict['left'] = ws.header_footer.left_header.text
    header_dict['right'] = ws.header_footer.right_header.text

footer_dict = {}
if ws.header_footer.hasFooter():
    footer_dict['center'] = ws.header_footer.center_footer.text
    footer_dict['left'] = ws.header_footer.left_footer.text
    footer_dict['right'] = ws.header_footer.right_footer.text

return header_dict, footer_dict

此header_footer模块可能提供了一种从Excel文件中删除这些文件的方法，但可以在文档中找到更多帮助OpenPyXL - Headers and Footers

尝试推杆工作表['B8']。value =“Customer07” 代替工作表['B8'] =“Customer07”

python的openpyxl模块的workbook.save（）无法正常工作
