python - 使用 xlrd 读取 excel 文件

Question

我在读取由我无法控制的 Perl 脚本编写的 .xls 文件时遇到问题。这些文件在单元格中包含一些格式和换行符。

filename = '/home/shared/testfile.xls'
book = xlrd.open_workbook(filename)
sheet = book.sheet_by_index(0)
for rowIndex in xrange(1, sheet.nrows):
    row = sheet.row(rowIndex)

这是抛出以下错误:

_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
   20  4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4
172480= 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4
172500  4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 3 2
172520  2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2
173840= 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2
173860  2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 1 1
173880  1 1 1 1 1 1 1 1

xlrd.compdoc.CompDocError: Workbook corruption: seen[2] == 4

我找不到任何关于 CompDocError 或 Workbook 损坏的信息，更不用说 seen[2] == 4 部分了。

来自 pkm 评论(link)，问题出在复合文件二进制上

#pip install OleFileIO-PL
import OleFileIO_PL
import pandas as pd

path = 'file.xls'
with open(path,'rb') as file:
    ole = OleFileIO_PL.OleFileIO(file)
    if ole.exists('Workbook'):
        d = ole.openstream('Workbook')
        x=pd.read_excel(d,engine='xlrd')
        print(x.head())
