如何将多个 XLSX 文件合并到一个工作簿中，同时保持它们的工作表分开？

Question

I'm trying to merge all.xlsx files within a folder into one workbook while keeping their worksheets separated. My code below is grabbing specified files, merging them into one workbook but only copying the first worksheet from each file instead of all their worksheets.

My output file is currently one workbook containing the first worksheet of each merged file but some files have multiple worksheets. Would anyone know how I can grab all worksheets from multiple files and combine them into one workbook?

Thanks for your time!

import win32com.client as win32
import os

excel = win32.gencache.EnsureDispatch('Excel.Application')
wb = excel.Workbooks.Add()

path = r'C:\Users\Desktop\merge'
files = os.listdir(path)

for f in [os.path.join(os.getcwd(), "Daily Pipeline"), os.path.join(os.getcwd(), "Loans")]: 
    w = excel.Workbooks.Open(f) 
    w.Sheets(1).Copy(wb.Sheets(1))


wb.SaveAs(os.path.join(os.getcwd(), "Final.xlsx"))
excel.Application.Quit()

Why dont you try reading the excel files using python pandas? You could use glob to read the files from your directory and then merge them into a dataframe.

import glob

all_data = pd.DataFrame()
path = 'd:/projects/chassis/data/*.xlsx'
for f in glob.glob(path):
    df = pd.read_excel(f, sheet_name=None, ignore_index=True, skiprows=6, usecols=8)
    cdf = pd.concat(df.values())
    all_data = all_data.append(cdf,ignore_index=True)
print(all_data)

This might do the work!
