从 Dropbox 链接解析 .xls 文件

Question

我正在尝试从 Dropbox 链接 (https://www.dropbox.com/s/i77mern7joxc9ur/TestResultCodelistVoC.xlsx) 解析表格。这是一个.xlsx 表，到目前为止我已经尝试了两种方法

方法一

codeID_url = 'https://www.dropbox.com/s/i77mern7joxc9ur/TestResultCodelistVoC.xlsx'

tables = pd.read_html(codeID_url)
df_codeID = tables[0]

给予

ValueError: No tables found

这是有道理的，因为最后，我不是从 html 页面解析表格。上面的命令非常适合本页中的表格 (https://www.ecdc.europa.eu/en/covid-19/variants-concern)

方法 2

codeID_url = 'https://www.dropbox.com/s/i77mern7joxc9ur/TestResultCodelistVoC.xlsx'
data = pd.read_excel(codeID_url,'TestResultCodelistVoC')

给予：

XLRDError: Unsupported format, or corrupt file: Expected BOF record; found b'<!DOCTYP'

我确实找到了关于同一错误 here 的主题，尽管所有答案都在处理 local .xls 文件，而在我的情况下，我正在尝试解析网页/链接，最后是一个.xls 文件。

我也遇到了一个使用 dropbox token 的解决方案，但我首先想尝试在没有 Dropbox 帐户的情况下下载上述表格。

将?dl=1 添加到您的网址末尾。

>>> import pandas as pd
>>>
>>> url = 'https://www.dropbox.com/s/i77mern7joxc9ur/TestResultCodelistVoC.xlsx?dl=1'
>>> df = pd.read_excel(url)
>>> print(df)
