Question

这是代码：

xls = open_workbook('data.xls')

作为回报：

File "/home/woles/P2/fin/fin/apps/data_container/importer.py", line 16, in import_data
  xls = open_workbook('data.xlsx')
File "/home/woles/P2/fin/local/lib/python2.7/site-packages/xlrd/__init__.py", line 435,     in open_workbook
ragged_rows=ragged_rows,
File "/home/woles/P2/fin/local/lib/python2.7/site-packages/xlrd/book.py", line 91, in open_workbook_xls
biff_version = bk.getbof(XL_WORKBOOK_GLOBALS)
File "/home/woles/P2/fin/local/lib/python2.7/site-packages/xlrd/book.py", line 1230, in getbof
bof_error('Expected BOF record; found %r' % self.mem[savpos:savpos+8])
File "/home/woles/P2/fin/local/lib/python2.7/site-packages/xlrd/book.py", line 1224, in bof_error
raise XLRDError('Unsupported format, or corrupt file: ' + msg)
XLRDError: Unsupported format, or corrupt file: Expected BOF record; found '\r\n<html>'

文件没有损坏，我可以用Excel，LibreOffice打开它。

Answer 1

对于.xls文件，您可以使用read_excel()：

df1= pd.read_excel("filename.xls")

参数header和sep可以帮助您摆脱一些错误（here you can find more info on the parameters）。用法示例

df2= pd.read_excel("filename.xls",  header = None, sep='delimiter')

请注意，如果文件为.csv，则会收到错误消息

XLRDError：不支持的格式或文件损坏：预期的BOF记录；

要阅读.csv，需要像这样使用read_csv()

df3= pd.read_csv("filename.csv")

我现在已经解决了同样的错误，第一步是进行ID检查，将文件更改为文本并注意到html内容，然后进行了一些修改，以确保一旦将其另存为HTML并在浏览器中打开，表格就应该可见。比美丽的汤和熊猫帮助我获得了出色的输出....

检查下面几行是否有帮助。

import pandas as pd
import os
import shutil
import html5lib
import requests
from bs4 import BeautifulSoup
import re
import time

shutil.copy('donloaded.xls','changed.html')
shutil.copy('changed.html','txt_output.txt')
time.sleep(2)

txt = open('txt_output.txt','r').read()

# Modify the text to ensure the data display in html page

txt = str(txt).replace('<style> .text { mso-number-format:\@; } </script>','')

# Add head and body if it is not there in HTML text

txt_with_head = '<html><head></head><body>'+txt+'</body></html>'

# Save the file as HTML

html_file = open('output.html','w')
html_file.write(txt_with_head)

# Use beautiful soup to read

url = r"C:\Users\hitesh kumar\PycharmProjects\OEM ML\output.html"
page = open(url)
soup = BeautifulSoup(page.read(), features="lxml")
my_table = soup.find("table",attrs={'border': '1'})

frame = pd.read_html(str(my_table))[0]
print(frame.head())
frame.to_excel('testoutput.xlsx',sheet_name='sheet1', index=False)

Answer 3

尝试用pandas打开它：

import pandas as pd
data=pd.read_html(filename.xls)

或尝试任何其他html python解析器。

这不是一个合适的excel文件，而是一个可以用excel读取的HTML。
