使用熊猫，如何只从 Excel 工作簿中读取一张工作表而不加载任何其他工作表？

Question

This is a little different from similar questions to this. I am using the FactSet plugin for Excel, if anyone's familiar. I have a workbook with multiple tabs that use the FactSet plugin to pull in data. No issues with this.

The problem is FactSet generates a hidden cache sheet for every Excel workbook that when read in causes loading any sheet of the Excel file by python to return an empty DataFrame.

I've tried two methods to get the data from the sheet, but both methods load the entire workbook causing the FactSet cache file to be read in.

import pandas as pd

fname = 'facset_excel_file.xlsm'

# method 1
wb = pd.ExcelFile(fname)
symbols = pd.read_excel(wb, sheet_name='Symbols')  # returns empty DataFrame

# method 2
pd.read_excel(fname, sheet_name='Symbols')  # returns empty DataFrame

So my questions are how can I read in a single sheet without loading the entire workbook? Or is it possible to exclude a worksheet by name when loading a workbook?

Answer 1

You can use something like, the file can be read using the file name as string or an open file object:

df = pd.read_excel(open('facset_excel_file.xlsm', 'rb'), sheet_name='123')

Try it.
