使用 pandas read_excel() 將.xls 文件格式導入 python 時出現 CompDocError

Question

我正在嘗試導入 IMF 的 GDP 數據。 它是一個 excel 文件，擴展名為 .xls。 當我嘗試使用以下代碼導入它時：

imf_data = pd.read_excel('C:\\Users\\amir\\Downloads\\imf_data.xls', sheet_name=None)

我收到以下錯誤：

_locate_stream(Workbook): seen
    0  5 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4

為什么會發生這樣的事情以及如何解決？

Answer 1

在我的例子中，它是一個帶有 a.xls 擴展名的復合文檔格式。

我們可以使用OleFileIO_PL package 在 Python 中打開這些文件。 我的真實例子：

import pandas as pd
import requests
import OleFileIO_PL

url = "https://www.cepea.esalq.usp.br/br/indicador/series/milho.aspx?id=77"
resp = requests.get(url)
ole = OleFileIO_PL.OleFileIO(resp.content)
df = pd.read_excel(ole.openstream('Workbook'), skiprows=3)
