无法加载工作簿（ <typeerror: expected <class 'openpyxl.chart.axis.numericaxis'> )</typeerror:>

Question

import openpyxl

wb = openpyxl.load_workbook('test.xlsm', data_only=True)
sheets = wb.sheetnames
x = wb[sheets[0]]

But I got this error:

TypeError: expected <class 'openpyxl.chart.axis.NumericAxis'>

What I understood is that openpyxl cannot open sheet with graph, not anymore at least.

But I only need on sheet, and there is no graph inside.

Is there a way to directly tell openpyxl to open only one sheet and not waiting after wb = openpyxl.load_workbook('test.xlsx', data_only=True)

Or if you have other ideas?

Apparently it's based on the source code so I'm kind of stuck with that. Source:

Answer 1

如果该包有一个错误导致您无法在完整文件上使用它，并且您找不到另一个包来代替，您可以尝试通过查找另一个允许您打开 Excel 工作簿的包来解决该问题，然后从中提取一张工作表到一个临时工作簿文件中，然后使用该临时文件进行 openpyxl 调用。

As Charlie Clark said, read-only mode helps (solved the issue for me when opening a XLSM file). This should work just fine, and possibly faster:

import openpyxl

wb = openpyxl.load_workbook('test.xlsm', data_only=True, read_only=True)
sheets = wb.sheetnames
x = wb[sheets[0]]

Be sure to read the openpyxl documentation on Optimised Modes because there are some caveats in read-only / write-only modes.
