Pandas 和 glob：將文件夾中的所有 xlsx 文件轉換為 csv – TypeError：__init__() 得到了一個意外的關鍵字參數“xfid”

Question

我有一個包含許多 xlsx 文件的文件夾，我想將這些文件轉換為 csv 文件。

在我的研究過程中，如果發現有關此主題的多個線程，例如這個或那個。 基於此，我使用glob和pandas制定了以下代碼：

import glob
import pandas as pd

path = r'/Users/.../xlsx files'
excel_files = glob.glob(path + '/*.xlsx')

for excel in excel_files:
    out = excel.split('.')[0]+'.csv'
    df = pd.read_excel(excel)         # error occurs here 
    df.to_csv(out)

但不幸的是，我收到以下錯誤消息，在這種情況下我無法解釋，我無法弄清楚如何解決這個問題：

有誰知道如何解決這一問題？ 非常感謝你的幫助！

我在這里遇到了同樣的問題。 經過幾個小時的思考和搜索，我意識到問題實際上是文件。 我用 MS Excel 打開它，然后保存。 阿拉卡山，問題解決了。

該文件已下載，所以我認為這是一個“安全”錯誤，或者只是文件創建方式的錯誤。 xD

編輯：這不是安全問題，而實際上是生成文件的錯誤。 正確的有 kb 的兩倍是錯誤的文件。 一個解決辦法是：如果使用xlrd==1.2.0可以打開文件，你可以在這樣做之后調用read_excel到Book（由xlrd打開的文件）。

import xlrd

# df = pd.read_excel('TabelaPrecos.xlsx')
# The line above is the same result

a = xlrd.open_workbook('TabelaPrecos.xlsx')
b = pd.read_excel(a)
