excel - Writing and modifying an existing workbook using Python

Question

I am new to Python and working on a project that I could use some help on. So I am trying to modify an existing excel workbook in order to compare stock data. Luckily, there was a program online that retrieved all the data I need and I have successful been able to pull the data and write the data into a new excel file. However, the goal is to pull the data and put it into an existing excel file. Furthermore, I need to overwrite the cell values in the existing file. I believe xlwings is able to do this and I think my code is on the right track, but I ran into an unexpected error. The error I get is:

com_error: (-2147023174, 'The RPC server is unavailable.', None, None)  

I was wondering if anyone knew why this error came up? Also, does anyone know how to fix it? Is it fixable? Is my code wrong? Any help or guidance is appreciated. Thank you.

import good_morning as gm
import pandas as pd
import xlwings as xw

#import income statement, balance sheet, and cash flow of AAPL
fd = gm.FinancialsDownloader()
fd_frames = fd.download('AAPL')

#Creates a DataFrame for only the balance sheet
df1 = pd.DataFrame(list(fd_frames.values())[0])

#connects to workbook I want to modify
wb = xw.Book  (r'C:/Users/vince/OneDrive/Documents/Python/Project/spreadsheet.xlsm')

#sheet I would like to modify
sht = wb.sheets[1]

#modifies & overwrites values in my spreadsheet (this is where I get the commerror)
sht.range('M6').value = df1

Your issue is the OneDrive referenced in your directory is not reachable by the program. This can be caused by many things. Improper credentials, OneDrive is off, or simpler the OneDrive does not allow access from a program rather then a user. Try downloading the file you wish to read and write and save it to a directory stored on your computer and point the program to the new directory and see what happens then.
