Pandas 0.22.0: IndexError: list index out of range when reading xls

问题

I'm trying to load a 282Mb (65536 rows x 138 columns) .xls file into a pandas dataframe

import pandas as pd
import os

filename = r'invoicing.xls'
dir = os.path.dirname(os.path.abspath(filename))
excelFile = os.path.join(dir, filename)
invoicing_info = pd.read_excel(excelFile)

But I'm getting this

Traceback (most recent call last):
  File "/Users/juanda/conda_envs/Hyperion_contracts_env/lib/python3.6/site-packages/xlrd/sheet.py", line 698, in put_cell_unragged
    self._cell_types[rowx][colx] = ctype
IndexError: list index out of range

During handling of the above exception, another exception occurred:

    invoicing_info = pd.read_excel(excelFile, sheet_name=0)

AssertionError

I think this is a problem with the .xls extension but I can't modify the file before uploading it. How can I upload this .xls file in a reliable manner?

回答1:

I was having the same issue. After i copied and pasted "values only" into a new sheet, move the sheet around (order of the sheet), it is working now. This is annoying.
