Does that help for Schollii, I was able to get on the right track. The following is what worked for me, I hope it helps you:
code :
for sheet in xlwb.Worksheets:
     xlApp = win32com.client.Dispatch("Excel.Application")
     nwb = xlApp.WorkbookAdd()
     sheet.Copy(Before=nwb.Sheet(1))
     nwb.SaveAs("C:\Users\user\AppData\Local\Temp\\" +sheet.Name+ ".xlsx")
     nwb.Close(True)

this one helps. I am trying to open excel file through win32com. But when I run a code with foreign(Korean) language then it gives an error which wans't happened with a english filename. , It was an encoding problem.
code :
#-*- coding: utf-8 -*-
import os
import win32com.client

xl=win32com.client.Dispatch("Excel.Application")
xl.Visible = True

xl.Workbooks.Open("C:\\Users\\Jongho\\dev_jhk\\VNI Automation Pilot Test\\Nikkei225_10\xbf\xf9.xlsm")

xl.Application.Quit() # Comment this out if your excel script closes
del xl

this will help I believe that the reason that is crashed is since when you are in the else section, you have the line book=xlwt.Workbook(fname2) which means the book type is Workbook which has no attribute called sheet_names().
When you are using book = open_workbook(fname2) inside the if, book type is Book which does have sheet_names() attribute.
code :
import pandas as pd
import xlsxwriter
from xlrd import open_workbook
import xlwt
import os.path

fname=r'testmonthlyz.xlsm'
fname2=r'testmonthlyoutput2.xlsx'
workbook = xlsxwriter.Workbook(fname2)    
if os.path.isfile(fname2):
    print('old file')
    book=open_workbook(fname2)
else:
    print('new file')
    workbook2=xlwt.Workbook(fname2)
    ws = workbook2.add_sheet('Tested')
    workbook2.save(fname2)
    book = open_workbook(fname2)

sheet_names=book.sheet_names()

wish help you to fix your issue I am trying to make a program to open existing excel files, in order to read and write their contents. I am already having trouble opening files. , I think your problem comes from:
code :
wb = excel.Workbooks(r'C:\Users\<username>\Documents\<more file path>\test.xls').Open()
wb = excel.Workbooks.Open(r'C:\Users\<username>\Documents\<more file path>\test.xls')
